Frequently Asked Questions
Will this buffer work with my pistol-length or rifle-length buffer tube?
No — the LBE Carbine Length Recoil Buffer is designed specifically for use with a carbine-length buffer tube only. It will not fit or function correctly in a rifle-length (A2-style) buffer tube or a pistol buffer tube. If you have a standard M4-style collapsible stock setup, you almost certainly have a carbine tube and this buffer will be compatible.
Is a standard carbine buffer the right choice for my AR-15 build?
A standard carbine buffer (approximately 3 oz) is the most versatile and widely used buffer weight for AR-15 carbine builds. It works well with mid-length and carbine-length gas systems across a variety of barrel lengths. If your rifle is over-gassed or you're running a suppressor, you may benefit from a heavier buffer. For most standard builds, this LBE buffer is an excellent all-around choice.
Does this buffer require any special tools or modifications to install?
No special tools or gunsmithing are needed. Simply depress the buffer retaining pin in your lower receiver, slide out your old buffer, and drop in the new LBE Carbine Buffer. The entire swap takes less than a minute and requires no permanent modifications to your firearm.
