When purchasing Aero Precision or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

Perfect for your new build or as a direct replacement for worn-out parts, mil-spec carbine buffer is tailored for use in AR15 carbines with a collapsible buttstock. The buffer weighs 3 oz.

The H Buffer, on the other hand, is a heavy buffer that is made to reduce felt recoil as well as lessen the cycling rate on full-auto rifles. It is designed to mil-spec standards and is suitable for use in AR15 carbines with a collapsible buttstock.

Also, the H2 Buffer is designed with the same intentions as the H Buffer. The only difference is that it is a bit more massive, with a weight of 4.65. Similarly, the H3 Buffer remains streamlined towards reducing felt recoil and the cycling rate on full-auto rifles. Designed to mil-spec standards, the H3 Buffer is for use in AR15 carbines with a collapsible buttstock.

For AR15 rifles with a fixed buttstock like the A2 or A4 style, you can efficiently use the Mil-spec. rifle buffer. However, it will not work with AR15 carbines that have a collapsible buttstock. Made in the USA, it is ideal for your new build or as a direct replacement for your worn-out parts.

Note that you should exercise caution when adding a heavy buffer to your rifle build, as it can prevent reliable function.
