Not a stainless barrel, but this is my experience with a PSA 12" CARBINE-LENGTH 6.5 GRENDEL 1/8 NITRIDE 10" LIGHTWEIGHT M-LOK UPPER - WITH BCG & CH.
I put a LaRue TranQuilo muzzel device on it and built a lower to go with it.
I bought this upper a few years back and there is no way I would pay the price they are asking for it now. Just my opinion.
Here are some 3 shot groups from today with it, using Hornady Black 123gr eld-m ammo. Last two pics have a 5 shot group fired by me with a tape for scale.
