AR-15 Buffer weights

[technetium-99m]

Andrei, your carrier is moving a bit faster now. Whether or not it is a problem is up to you to determine. Removing too much weight can cause feeding and extraction problems, if you're not seeing issues you're likely fine.

It is a 16" carbine, brass ejects at 3:30 o'clock (no deflector) - I don't feel like it's recoiling any different than my A2 rifle clone.
It's my deer/skunk gun - so it doesn't get fired a lot or rapid.

I moved to a H2 buffer on my suppressed SBR and I think it helped with blowback.

A standard full auto bolt carrier weighs around 8.5oz to a little over 9oz. A JP low mass carrier weighs 6.25oz, as stated on their website. Therefore you take away 2.25oz+ from the system. The 3 steel weights in a standard carbine buffer weigh approximately 1.9oz, which is less mass than the low mass carrier removes. Considering the entire assembly acts as a system (it is all reciprocating mass)...I wonder what those same people spouting falsehoods would say about simply switching to a low mass carrier?

They are probably also running the JP low mass buffer.
