Question Re: PWS Piston AR Pistol Acqquired in Trade

[georgeib]

Is PMC any better? That's the other stuff I have.

Is it PMC Bronze or X-Tac? The Bronze will be no better, and is some of the softest loaded brass ammo available. The X-Tac on the other hand is good to go.

Either way reaming the 2nd port on the gas plug a hair bigger will solve your problem in a few seconds. You will need to know how big the port is on your gas plug, and just order a full carbide bit that is 1 size larger. It really is simple, and not easy to screw up, besides PWS will send you another gas plug if you ask them nicely.

Sell it and get a good DI carbine, period

Maybe he should get an AR instead

I have a Mk114 that's very consistent between cheap fmj's and 77 gr stuff and another load I can't think of, extremely similar poi at 50, still able to get hits with same hold at 300. I suspect it's because of the piston tube stiffening the barrel or doing something to the harmonics, because the heavy barrel DI rifle I shot the next day while more accurate than me was all over the place with different loads.
