Stock/Buffer Combo
« on: September 06, 2018, 04:34:33 AM »
Curious to what everyone is running for a stock/buffer/spring Combo.  I'm hoping to run my standard carbine but after my first few test firings, my brass was ejecting at about 1:30-2:00. I may need to go rifle length buffer tube or try to run a heavier buffer on my carbine setup.  Thanks guys.

Using standard carbine stuff.  Non adjusting gas block and haven't had a single issue.  I have around 400 rounds down range so far.

On my PSA 20" with adjustable gas block, I have a Magpul rifle length stock and buffer and the gas block "tuned" to the load. Eject at 3 - 3:30 about 5' away. On the other hand, when I use the Fed 75 grain TMJ for zeroing or to foul the barrel, it ejects at 1:30 - 2:00 with the same setup.

Just thinking out loud but if your Valkyrie I assume has a rifle length gas system and  you're running it on a carbine lower it's going to be undergassed.

Interesting.  At the time I was using the Federal 75 grain TMJ rounds.  Maybe I'll try adjusting the gas block that came on my PSA upper.  Just not sure which screw adjusts the gas flow.  Either the side or the front.  Maybe someone here who has a PSA upper may know.

Rifle length system, Adams Arms piston system, Magpul PRS rifle tube with an Armaspec carbine spring spacer and Spikes tungsten 4 oz buffer. Works great.

24” BSF barrel, Ergo 8 position stock with JP tuned spring and Spike’s 4 oz Tungsten buffer. Has rifle +2 gas system. Had to use slower burn powder, like H380, or CFE 223 to get it to eject at 4:00.

I'm using a JP-Rifle Silent Buffer carbine H2, and a Superflative Arms adjustable gas block.

One range trip to tailor it to my handloads and not a single malfunction since.  Tested it with the cheap 70gr FMJ Federal stuff and no malfunctions with that either.  Runs suppressed and unsuppressed equally reliably.

If you don't want to spend the money on the JP Silent Buffer (yeah, it's expensive), I'd say a milspec carbine H2 is probably going to perform the exact same.  But it sure is nice not getting the AR "SPROING" in your ear when you're firing suppressed.....
