Complete Guide to Buying
Prices aside, every part of your AR-15 build is considered an added weight. Hence, you must also consider buying an AR-15 lightweight butt stock. Generally, weight is a critical factor in your AR-15 rifle’s performance, as it plays a vital role in keeping the balance of your weapon. Buyers usually consider the materials used, the design and construction of the buttstock to determine its weight factor.
This AR fixed stock has no room for any adjustment. One example of a fixed stock is the classic M16 stock. Furthermore, this stock is generally every shooter’s basic option. Fixed AR-15 stocks feature small compartments for small tools such as small containers for lubricants and extra batteries. However, a fixed stock is also durable enough to withstand any harsh weather conditions.
The collapsible AR-10 stock is adjustable but only to add to the stock’s length of pull. Generally, these AR-15 stocks are collapsible and expandable. These AR-15 stocks provide more comfort in every shooter’s stance when used in shooting or firing because of your arm length or when you have any additional gear.
However, our team suggests that you always do your research when using or buying collapsible stocks. Some states do not allow folding stock/collapsible stocks, as they declare these buttstocks illegal.
Adjustable stocks can be adjusted in ways other than how collapsible buttstocks extend the length of pull. These precision stocks are like fixed stocks but may have an adjustable butt padding or a cheek riser. These precision stocks may also provide a small compartment to hold small tools or necessary items.
Folding stocks make it easier to carry or pack your AR-15 rifles. However, these buttstocks may or may not be allowed to be used in your state, so our team suggests that you verify the existing laws in your state. In some states, rifles that fold under 26 inches are already considered short barrel rifles (SBR).
The minimalist type is an extremely lightweight AR-10 stock. Thus, it is the gold standard for carrying for long-distance hunting escapades or in tactical situations. If you like to hunt long distances or opt to hunt for a longer time, this type is perfect for you. This could be a fixed stock/ collapsible stock, but it provides a low profile.
The last stock product is an extremely compact AR for CQB or any other tactical situation. It comes with its own AR-15 buffer system and accommodates a shorter buffer tube. However, some PDW stocks are mountable to a standard mil-spec buffer tube. This stock is more durable and more compact than any standard polymer stock.
Most first-time builders consider the installation process one of the most crucial factors before buying an AR stock. Based on our research, AR-15 stocks may become a little tricky to install for first-time builders like pistol braces. Therefore, we always suggest finding a buttstock that is easy to install and easy to remove, like the MOE SL. See our comparison between Magpul SL and SLK here.
Generally, the materials used in an AR stock determine its durability. Based on our team’s research, the most popular choice for an AR stock material is a polymer.
Synthetic polymer materials have many attractive properties, such as monodispersity, biocompatibility, controlled composition and chain length, and tunable chemical properties. 
Therefore, the polymer is extremely durable and lightweight compared to aluminum materials or any nylon rifle stock.
The design options are also an essential consideration that buyers should always take note of. We suggest that you look for stocks with a sleek design but fit perfectly, as it drastically improves the overall performance of your AR-15 rifle. Like pistol braces, it is also best to look for design options that provide comfort and balance, matching your shooting preferences at affordable prices. Check out the best SKS stocks here.
Although prices can climb higher when there are more special features, it is still essential to look for special features when buying an AR stock. Additional storage is commonly found on stocks, which is very handy when storing small tools such as optics, extra batteries, and lasers. You can also look for stocks with a built-in 10-round magazine carrier or similar storage compartments, which could benefit your shooting activities.
You can go to any local stores near you to check the products one by one for more options. You can also go to the official website of each company to learn more about the special features and prices of these stocks.
And the #1 AR-15 Stock is...
Our team chose the #1 AR-15 stock to be the Magpul Industries STR Mil-Spec based on extensive research and testing. This collapsible stock comes with two water-resistant battery tubes, giving you extra storage located at a more accessible place. It also provides a supplemental friction lock, minimizing the wobble and maximizing the accuracy of your every shot.
This buttstock is also constructed from a premium chrome-silicon lock spring, which ultimately gives it a more extended service life. You can also find more comfort when using its sloping cheek weld, as it provides a wide contact surface. And lastly, it comes with a shielded release stock latch and a rubber buttpad that adds protection against shoulder impact and any accidental operation.
