What buffer should I buy for my SPR build? 18" barrel, rifle length gas system. It'll probably have a can on it half of the time.

I am using a standard rifle buffer and it works fine.

This if you can stand not having a collapsible stock. If you need a collapsible stock, the Vltor A5 system is pretty much the dynamics of a fixed stock in a collapsible package.

I learned to get away from carbine springs and buffers, life has been much more pleasant since.

Magpul PRS stock with a standard rifle buffer.

I love my Vltor A5 system, it runs great with or without a can.

I run H2 buffers in a 10.5 223 and 8.0 300BO. No issues suppressed or not.

I run an H2 buffer in my 14.5", 16" and 11.5" 223s with a full-weight bolt-carrier and they run fine suppressed or unsuppressed. Of course, my current can for these is a 762 YHM phantom (read: big diameter bore).

(Edit) As additional info: On my 14.5" (which I shoot most often suppressed), I get perfect 3 O'Clock ejection about 3' from the rifle.

i have shot a lot of suppressed DI .223 ar's and haven't had a hickup yet on a standard buffer...I know however that this isn't always the case.

I'm running the Magpul UBR collapsible - with a Spikes Tactical ST-T2 tungsten filled buffer.
