    M4 Buffer

    Good morning, I’m looking for recommendations for a Buffer weight for a M4 with a 12inch barrel. It currently has a 2.9 oz and I read I my see improvements with a heavier one. Any thoughts? Ammunition is standard 55 grain.223

    It will depend on a combination of factors; how is your barrel gassed, the .223 you refer to- will it be the ONLY ammo you're shooting(?).
    It would be advisable to set your Carbine/Pistol up to function with milspec ammo (m193 as example) in addition to the .223 you mention.
    You never know what may be available down the road.

    What barrel are you using, manufacturer?

    I'd consider a BRT gas tube if your barrel is overgassed (which it probably is), in combination with an H1 buffer. I run an H2 with Clints BRT gas tube on an 11.5" BCM. It is exceptionally soft shooting with m193 and mk 262.
    I would get an H2 and try it. You can always remove one og the Tungsten weights and replace with a Steel weight from your Carbine/current buffer- which will be an H1 buffer.

    A true "Gun Guy" (or gal) should have familiarity and a modicum of proficiency with most all firearms platforms.

    What kind of improvements are you anticipating?

    Who made the gun/barrel? Tell us a little more about it.

    By the way, welcome and M4s have 14.5" barrels.

    What’s wrong with the gun in its current state?

    H2 buffer for sure. I don't mess with non-Colt/spec buffer springs.

    The H2 is a good starting point before you even look at gas issues.

    In that case, I’d suggest buying a a few tungsten weights and subbing them in and see what happens. Or if you don’t have/don’t want to buy a roll pin punch, do what Markm said and buy a H2 buffer. Or, leave it alone.
