Any success with rifle length buffer

[GJGary]

Any success using rifle length buffer tube,  spring, buffer weight ect in 9mm ar instead of a carbine length tube.

Have a rifle length I would like to use if possible.

I think jp makes a spacer for pcc that works in a rifle length tube using a carbine buffer/Spring.

Hello: I think it would work just fine. Remember you need the buffer in the 9mm range of weight. I would use a 223 spring and a buffer weight of 5.6ozs or so to start if you are using reloads in the 130-140PF. Heavier weight if using factory ammo. That should be close with a 16" barrel. Thanks, Eric

CJ... I use a rifle length buffer and tube... if you want to play around with DIY weights in a rifle buffer

 

filled with 7 1/2 shot... 6.0

1/2 brass plug....6.2

5/8 brass plug... 7.0

filled with poured lead...9.0

 

after trying the heavier buffers I switched back to the stock 5.2oz rifle buffer and tube
