What buffer to use

Posted: 8/20/2017 8:23:18 AM EDT

I'm building a lower for the BCM-URG-SS410-20SAMR-KMR-A-15 upper and don't have a buffer. What would be a good buffer to start with?
Thank you
Billy

H2 or a Vltor A5 system.

H2 in any carbine length gun.

Per the BCM website, this is a 20" barreled URG.

I believe with this upper having a 20" barrel there's not much point in using a carbine stock. So I may just go with a rifle stock, A1 or A2 tube with rifle spring and buffer. Things may run better this way.
Thanks for the replies

The point of a "carbine" stock is the wide choice of stocks. In any case, the rifle should run great with a rifle stock spring and buffer.

It'll run with any buffer you put behind it.

If you go with a carbine tube, an H2, H3, or H6 would work fine. I'd lean toward H6.
