OUR #2 RATED

Aero Precision - AR-15 Carbine Buffer Kits

OUR #3 RATED

Brownells – AR-15 Heavy Carbine Buffers

1. Primary Weapons – AR-15 Enhanced Buffers Carbine Black

Why We Picked It:

Primary Weapons always have exceptional products ever since they set foot in the market,

The PWS Mod 2 Steel Body Buffer line is designed with a fluted contact surface with minimum contact points, allowing debris to clear quickly. 

This line of buffers is practically an upgraded version of what first came out from PWS. 

As expected from this manufacturer, the make of this buffer is just exceptional. 

They used FNC LIFE HD surface treatment that chemically bonds in lubrication for smoother cycling for the body of the buffer. This comes in three sizes, H2 being 4.4 ounces, H3 5.1 ounces, and H4 weighing in at 6.8 ounces. 

If you are using ammo that is more powerful than the usual, this can be the buffer tube you can pick. Also, if you have a shorter barrel length, then this can also be your choice.

Who Should Use It: 

This works best for those who shoot at the range. This rifle buffer is guaranteed to slow down the rate of fire and reduce the felt recoil, even the lighter buffers.

Summary: 

It’s on top of our list because of its impressive features. It uses FNC LIFE HD surface treatment that chemically bonds in lubrication for smoother cycling for the body of the buffer, making it ideal for any ammo.

2. Aero Precision - AR-15 Carbine Buffer Kits

Because of over-gassing, short barrel rifles became popular, and Aero Precision took advantage of the chance. 

They released the AR-15 Carbine Buffer Kits to improve the resilience of SBRs and carbines against wear and tear.

It also comes in kits with buffer tubes and springs included. SIzes are the usual H (Heavy), H2, and H3 kits available that weigh in at 3, 4, 4.6, and 5 ounces.

It also includes a Mil-spec buffer tube made from 7075-T6 aluminum that is for six-position buttstock.

EDITOR’S CHOICE

We are sure that it can enhance the usual performance of your rifle whether you use it for recreation or competitive reasons.

Who should use it: 

These are good for guys who go out for recreational hunting or use it for competitive shooting.

Summary: 

If you want durability and performance all rolled into one, this is the suitable buffer for you. It can lower felt recoil, and you won’t have a hard time searching for the weight that fits your gun/ There is a lot of it available.

PROS

CONS

3. Brownells – AR-15 Heavy Carbine Buffers

Why We Picked It:

This is one of the most reasonably priced buffers in the market. 

These are the heavy buffer weights that come in aluminum casing and have a regular plastic cap. 

This is a heavier buffer that goes in a standard buffer tube, meant to be used for rifles that have short barrels.

This also goes with guns with carbine-length systems since the weight fits the AR 15 very well to control it when fired.

If you shoot more powerful ammo than the standard 5.56 or .223, you better check this out. Note that H1 buffers are the lightest standard carbine buffer weight inside a buffer tube. 

This is still heavier than the regular sold ones. You may need a stable carbine spring for this. Despite the difference, this still helps smooth out the action and delivers slightly less recoil. The kit includes a buffer spring that will fit any standard AR-15 lower receiver and a rifle-length buttstock.

Who Should Use It:

These are best for home defense use or competitive shooting. 

Summary:

Out of the average, the heavier weight on all sizes is what this product from Brownell offers. Made of standard aluminum construction, it has enough power to control recoil. 

It also helps protect your buffer tube in the unlikely event where your buffer bottoms out, especially with the buffer spring included. The buffer does not have problems in pushing the bolt carrier forward, ensuring the rounds cycles.

PROS

CONS

4. Brownells – AR-15 Carbine Buffer

Why We Picked It:

Brownells have many offerings in the carbine department, and this one is also making a name. 

Compared to the other buffer we talked about, which is heavier, this one has the standard weight. 

You still get regular weights, separated by rubber washers. The finish is very satisfactory, with no burrs or scratch marks. You won’t have any problems fitting it inside any standard weight buffer tubes.

This is for carbine-length gas systems, but this is also compatible with ARs that use mid-length gas systems.

The reason why we said it would work with mid-length gas systems, even better, because the amount of gas entering the upper receiver is lower, causing the impact of the bolt carrier group on the buffer to be reduced.

Who Should Use It:

It fits all types of shooters. However, this is best for beginners who are new to using AR carbines buffers. 

Summary: 

As we mentioned, this is a regular type of AR 15 buffer that does its job pretty well. It is compatible with both carbine and mid-length systems, and it is very affordable.

PROS

CONS

5. Kyntec Corporation – AR15/M16/308 Ar Recoil Buffer

Why We Picked It 

This is one of the hydraulic recoil buffers from Kyntec. 

Not a veteran manufacturer in the industry, but could build a name because of their highly durable carbine length buffer.

This one is for the AR-15 to fire 9mm rounds.

Unfortunately, these buffers from Kyntec are not that compatible with all types of rifles.

The brand is known for the hydraulically dampened piston, used to soften the impact of the bolt carrier group, which results in stable firing.

Compared to other commercial buffer tubes, this one assures a smoother operating system, regardless of weather conditions. Oil leakage is not a big problem here, even if you are shooting fast.

Also, the bolt stops behind the catch, resulting in a soft recoil impulse allowing the shooter to do faster follow-up shots. Regardless of the rifle length, buffer tubes from Kyntec will work the same superb way.

Who Should Use It: 

Competition shooters are the most that will benefit from these types of AR-15 buffers as it allows them to make easy successive shots.

Summary:

If you are looking for a durable buffer for your 9mm AR-15, this is the best fit. Durability is not the only feature it brings to the table but also its control; on recoil impulse.

PROS

CONS

6. Kyntec Corporation – AR-15 9mm Hydraulic Recoil Buffer

We were not expecting much since Kyntec is new to the industry, but they truly impressed us with the shock absorbers and rate control devices they produced. 

They assured the public that the Kyntec AR15/M16/308 Recoil Buffer has a ten-year and one million round guarantee.

The Kyntec AR15/M16/308 Recoil Buffer is a hydraulic buffer in a stainless steel case with a high-impact striker cap, fully sealed and filled with high-grade hydraulic oil. 

All these descriptions only talk about one thing, and that is durability, built to last.

When it comes to performance, this is also bound to work best in lessening felt recoil. The recoil management system built on these rifle buffers is very well thought of.

Who Should Use It:

There is no limit on who can use these pieces of steel buffers. Members of the military, law enforcement, or a competitive shooter will have fun using it.

Summary:

Durability at its finest. This is what the manufacturer focused on. Take note that the hydraulic piston of this buffer tube is made of solid steel. It has the right buffer tube that helps with felt recoil.

PROS

CONS

7. Liberty Suppressors AR-15 Buffer 4oz Stainless Steel

Why We Picked It

The very first thing that you will notice with this buffer is the make. Instead of the usual aluminum, the most heavier or lighter buffer, this is out of stainless steel.

Now, this is talking about durability made to last types of a rifle length buffer tube.

Another thing that got our attention with this rifle buffer is its ability to work and enhance the performance of any carbine gas tube length when it is supposed to be for suppressed rifles.

Now we are talking about compatibility and flexibility in a buffer tube.

These are heavier buffers compared to the regular ones in the market, but it serves well. 

Last but not least, it boasts a five-faceted cut to improve gas flow around the buffer which works to minimize gas blowback and reduce the chances of your shearing off your retaining pin.

Who Should Use It: 

This is best used for an action-packed adventure in the shooting range. Felt recoil, although successive shots are not going to be a problem with this buffer tube.

Summary

If you’re searching for a proper buffer that works with the most common buffer springs and buffers that prevent bolt catch breakage, this is a good choice. It’s also a very durable buffer tube.

PROS

CONS

8. TRYBE Defense AR-15 Buffer Tube

Why We Picked It

One of the rare features of buffer kits is an enhancement of the materials made. Some are using quality steel or aluminum, but Trybe took it an extra mile.

They designed their AR 15 carbine buffer tube with protective oxide layer coating called anodes(1) to make it durable along with the right buffer weight.

That is mainly why most AR15 owners choose to use this carbine buffer with their short barrel gun.

A typical comment from users is the simple installation of the carbine buffer regardless of carbine length or buffer weight.

This needs the carbine standard buffer assembly for a short-barrelled gas system. This AR 15 buffer also has a clean and smooth finish which is very pleasant to the eyes. The threads and cut out for the detent line up perfectly.

Who Should Use It: 

Home protection owners can benefit from this or regular hunting enthusiasts as well.

Summary

As mentioned, what sets it apart is the anodized make. The quality of this product is admirable despite the lesser than the regular brands’ price. The rifle spring comes with the kit, and it works with the regular short barrel tube.

PROS

CONS

9. Fm Products - AR-15 FM-9 Heavy Buffer

Why We Picked It

We can say that this product is for a 9mm caliber carbine because of its unique needs.

It works perfectly with .223/5.56mm standard buffer tubes rifles, assuring that it will work well. 

If your rifle has a strong recoil kick, then this one would fit just right. IT has a slight weight difference to make it cycle properly,

Another noticeable thing about the Foxtrot Mike Products AR-15 FM-9 Heavy Buffer is that it is slightly longer than the standard AR-15 buffer tubes.

Let us not forget that the buffer is finished with a salt bath nitride melonite/QPQ coating to help reduce friction and improve corrosion and wear resistance. 

 Who Should Use It: 

Law enforcers are regular users of this carbine buffer. It will also work very well for competitive shooters in the shooting range.

Summary: 

Cut out for 9mm calibers because it fits and works well because of its buffer weights. It is also durable because of the salt bath nitride melonite/QPQ coating. It even works to slow the bolt down to prevent and minimize unnecessary wear and tear on your upper receiver.

PROS

CONS

10. Rock River Arms

 Why We Picked It

This is something special since this is compatible with any rifle length or mid-length gas system. 

This works practically in almost any rifle-length buffer tube, rifle and carbine springs, carbine action springs, or any gas port size.

This type of AR 15 buffer tube reduces the impact of the bolt carrier group.

As long as it is a standard carbine buffer weight and size, the Rock River Arms AR-15 Carbine Buffer fits into any carbine buffer tube designed for a collapsible buttstock.

It features a standard polyurethane cap to help soften the blow and is made with coated aluminum and steel weights.

Who Should Use It: 

Law enforcers. Military, regular hunters, and competitive and occasional shooters will enjoy using this AR 15 carbine buffer.

Summary: 

This is probably the choice of many, mainly because of its compatibility. It does not have too many issues whether the gas system used is the standard one or not. The buffer spring lengths are also not a problem, and the carbine action spring of any AR 15 buffers.

Your Guide to Buying

Lunde Studio Buyers Guide_v2

Buffer Material

  • Tungsten – If you want heavy carbine buffers, then this is your choice. Fact is, tungsten is naturally heavy. Therefore the AR 15 buffer that is made of it will have that added tungsten weights at around 1.5 oz. on average.
  • Steel – Durability is what a steel buffer tube offers, and it weighs 0.62 oz
  • Aluminum – A single aluminum buffer weight is 0.22 oz on a regular length buffer, making it the lightest among the three.

Length

You need to get your rifle’s stock before you decide on your choice of AR 15 buffer. Initially, when Eugene Stoner designed the AR 15, he used the 6 inches long variant. 

The buffer tube it was in was longer than the existing buffer these days, at 7.625 inches compared to its 9.625 inches. 

The reason for that carbine length buffer tube length is because it was meant to be used within a fixed A2 buttstock.

Buffer Weight

  • Rifle – A regular buffer tube comes in five steel weights and a steel spacer, adding up to 5 oz.
  • Carbine – Buffers come with three steel weights and usually come up with a total of 3.0 oz. in weight.
  • H – A heavy buffer has a combination of tungsten and two steel weights to make a total of approximately 3.8 oz.
  • H2 – They have the same design as the H buffer but weigh more at around 4.6 oz. on average.
  • H3 – The design is almost the same as the H and H2 buffer, but the H3 comes with three tungsten weights and often weighs around 5.4 oz. This is also one of the heaviest types of buffer available.

Spring Quality

Some shooters disregard the importance of the buffer spring.  However, its importance is the same as the other parts of an AR-15 rifle to have a reliable function. Rifles and springs, in general, have the same sizes and diameters. 

Therefore, you do not have to worry about this part. 

They may have the same buffer weight, but you have to look at the length cause this is where they vary.  Choose a spring with a lubricated finish and smooth to lessen the “ping” sound whenever you fire your rifle.

Durability

When it comes to durability, you can always do background information about the materials used. Some anodized the steel. Others coat it with other special chemicals to ensure that it lasts for as long as you use it.

Resistance to Corrosion

We have the same logic here when it comes to corrosion. The materials are usually enhanced with coats and covering to withstand the change of weather.

Recoil Reduction

The main reason you are searching for a buffer is to lessen and feel recoil if not eliminated. The rifle’s blowback against the shoulders whenever fired is too much to endure, especially if you regularly do the activity.

Buffer Price

The buffer price should always depend on the quality of materials it uses. If the materials go through many processes, then the rifle buffer is built to last or a focused strength of that specific buffer.

Mil-Spec vs Commercial Buffer

Comparing the two would always be a matter of pricing. The concept will be behind the processes it passes through and the materials used. Commercial buffer tubes are to provide the functionality it is for. However, the durability and the extra performance are not guaranteed since these are just for regular use.

Mil-Spec buffer tubes, on the other hand, are designed to provide a particular function, but the downside is, there will be added cost to that because it went through rigorous testing, design foolproofing, and a lot more.

Our Team's Selection Process

Overall Performance

Considering that all products in the market almost have the same functionalities, we checked on its overall performance. Will it work on a specific gas system only? How long will it last? Does it require a specific weight?

Our team checked all these questions that the AR 15 buffers we present are not just a single performance type. 

Weapon Compatibility

There are gas systems and length that needs to be considered that is where the problem begins. Most of the buffers are built for a specific system only and do not function well. 

Product Quality

The most important basis of our choice is the voice of the customers who either are content or are in disdain. All manufacturers will always claim that they have the best products there are, which are with the highest grade materials. But based on the customer’s review, we were able to see whether the claims are accurate compared to what they got.

FAQs

You need to use a heavy buffer with AR 15 to ensure that your rifle cycles extract entirely and eject the spent casing and load a new round in the chamber without any problem.

Sometimes, the heavier buffer you use, the better.

We would say it depends on how you use your gun and its stock.

If you use this constantly and the performance is not smooth or even stable, you may want to check if it is compatible with an upgrade.

In answer to the question, we say yes. 

This can be the best buffer weight you can get.

After a shot, the bolt carrier group (BCG) contacts the buffer as it goes backward within the tube, and the weight of the buffer and tension in the spring resists the backward travel of the BCG.

So, What's The #1 Buffer Tube For AR 15?

Our number 1 choice is Primary Weapons AR-15 Enhanced Buffers Carbine Black. There is no question with quality as they have always delivered what they are claiming with their products: durability and functionality.

What made us say “wow” is the capability of the product to function with more powerful ammo. Another aspect that made us decide on PWS is the quality of materials used. 

As we always point out, regardless of the price, will it last? You can be sure that these are not using low-grade, low-density tungsten powder like the tungsten buffer shooters are complaining about.
