Standard Carbine Buffer Weight for AR15

This one-piece carbine buffer weight with rubber head weighs in at 3.0 oz, standard weight for AR15 buffers.  This is typically the ideal weight for AR gas systems with 16 to 20 inch barrels.    This buffer can only be used in AR rifles with carbine-length buffer tubes – it should not be used in rifle-length buffer tubes.

If your firearm is using too much gas and producing too much recoil, consider using AT3’s 4.2 Oz H2 Buffer Weight to improve feeding and reduce recoil.

Works Perfect

I had an odd situation where I bought an AR that had been a display on the wall for 12 years, and the first round of firing the original buffer came apart in the tube. This was a great, economical replacement that popped right in and functions perfectly.

Thanks for the review. We're glad to hear that the AT3 carbine buffer worked perfectly for you!
