Top 3 Buffers for 7.5 AR Pistol
1. Spikes Tactical T2 Tungsten Buffer
The Spikes Tactical T2 Tungsten Buffer is one of the softest shooting, smoothest, and quietest buffers on the market today. This buffer is carefully made of aluminum with a crushed tungsten Mil-Spec bumper.
This model has a black anodized finish that offers excellent performance at a reasonable price. Another great thing about this buffer is it is also maintenance-free.
PROS
- Maintenance-free
- Tough Anodized finish
- Tactical Lifetime Warranty
- Budget solution for recoil reduction
CONS
- Sloppy movement in commercial buffer tubes
2. Colt - Carbine H2 Heavy Buffer
The Colt – Carbine H2 Heavy Buffer’s increased weight allows more reliable rifle functions with shorter gas systems, reduces bolt bounce in a full-auto fire, and softens recoil. This buffer replaces two steel weights with a pair of tungsten weights and nearly two ounces to a buffer stock. An H2 buffer is likely too heavy for many mid-length systems. For most 7.5 AR-Pistols, shooters need heavier buffers to compensate for their terrible recoil. Unfortunately, a standard carbine buffer is far too light and will likely result in the action’s violent cycling
PROS
- Reliable function
- Reduces bolt bounce in full auto fire
- Softens recoil
- Allows for a longer dwell time
CONS
- Only works best with hot ammo
- Not designed for civilian spec
3. PSA AR-15 H2 Buffer
The PSA AR-15 H2 Buffer is a high-quality heavy buffer that will make your 7.5 AR pistol perform better with less recoil and noise. This buffer is machined with billet aluminum with a hard black coat and anodized finish, making this one of the best H2 buffers on the market. It gives 7.5 AR pistols a very buttery cycle, so it barely moves off-target.
The H2 buffer dramatically reduces recoil and allows your 7.5 AR pistol to cycle on Full Auto much better than standard buffer with any gas length. This buffer will lower your recoil, slow your bolt speed, and have smoother timing, unlock, and ejection.
PROS
- Reliable
- Lowers recoil
- Slows bolt speed
- Smooth unlock, timing, and ejection
CONS
- Over gassed
Buying Guide
Buffer Material
If you plan to buy buffers for your 7.5 AR pistols, make sure you pick the right material. Most 7.5 AR pistols have heavy recoils and most often than not over-gassed. Don’t settle for anything cheap like a plastic buffer. Find buffer tubes that are made from high-quality materials like aluminum, Mil-Spec steel, and Stainless Steel.

Length
Since 7.5 AR pistols are shorter than AR 15 rifles, you have to consider the buffer tube’s length that you plan on putting on your pistol. Although most buffers are compatible with almost every AR rifle, you can’t just put longer buffers to your generally shorter pistols without considering its consequences. Consider carbine buffers for mid-length rifles for better results.
Spring Quality
Buffers would never function well without a high-quality buffer spring. So, if you want to invest in a good buffer for your 7.5 AR pistol, you have to invest in a quality buffer spring, too.
Buffer springs must be made with high-quality materials to ensure the stability and reliability of your pistol’s performance. Usually, standard carbine springs measure about 10.5 inches and have 37 to 39 coils.
Buffer Weight
Most 7.5 AR pistols have terrible recoils, and you need heavier buffers to lower that. But be careful in using buffers because having too much weight in the buffer can cause the 7.5 AR pistol to short stroke. In looking for the best buffer for 7.5 AR pistol, remember that the pistol’s gas system may not have the necessary power to cycle the heavier buffer, causing inconsistent extraction ejection. Anyway, the H2 buffer is usually the best buffer for a carbine gas system and a pistol gas system, so it should not be much of a problem.
Installation
It should not worry you to install buffer tubes because most buffers are easy to install, given the right tool and enough time to do so. Most buffers come with installation guides, too. Some of which could be found mostly on their official websites and YouTube channels.

Buffer Pricing
If there’s one thing that you must always remember, it should never compromise quality over cheaper value. You wouldn’t want to compromise your 7.5 AR pistol’s performance with cheap buffers.
Ineffective cheap buffers would not only ruin your firearm but could even make it worthless. Here’s a tip for you, too. If your pistol’s buffer isn’t faulty yet, you don’t need to change it.
Remember, if your existing buffer is not giving you intolerable recoil, stick with the same buffer weight.
Compatibility
In most cases, buffers are often compatible with most AR rifles and pistols. It should only depend on the buffer’s length and weight to optimize your pistol’s capability and performance fully. Compatibility, size, weight, and performance should all be considered in finding the best buffer for your 7.5 AR pistol.
