What buffer weight is best for 300 Blackout?
Carbine Buffer Weight | ~3 ounces Your AR-15 might feel “over-gassed” and a little more violent. If your rifle build is chambered in 300 Blackout, the carbine buffer weight should be used with subsonic ammo and a pistol-length gas system. This combination will achieve the best possible operation.
Does a heavier buffer reduce recoil?
If it’s over-gassed, and you don’t have an adjustable gas block, adding a heavier buffer can noticeably reduce felt recoil. If you do have an adjustable gas system, reducing buffer weight can do wonderful things.
Is a heavier or lighter buffer better?
With a heavier buffer weight, the BCG encounters more resistance rearwards. The entire action becomes smoother, especially the felt recoil. But an overly heavy buffer isn’t good for a rifle, either. It will prevent the AR-15 from cycling, leading to improper extraction and ejection.
