I have a PWS MK212 308 with 12.75” barrel. It is suppressed using a Sandman S.
I love this rifle. Handles any ammo I throw at it, suppressed or not. The adjustable gas system is on point and very easy to dial in for suppression, ammo power, etc.
Only issue I had when I first got it was at the range for this first time. during zeroing and subsequent shooting, I noticed the 3-prong flash hider was missing. Looked for it but was unable to find it. I reached out to their customer service and they send me another one for free. I installed that one and the same exact thing happened, but this time I found the FH about 25 yards away. Remounted and used rock set and haven’t had an issue since.
During the FH issue, I inquired about the ratchet buffer system that the MK212 didn’t have. They send one for free and called it “warranty work”, and they also sent me a couple of different weight buffers and a spring. This was done because they don’t make the MK212 anymore and Adam wanted to give me some spare parts.
That being said, as far as the rife goes, it is a bit heavy due to the piston system, but the long stroke AK-like piston is amazing. Runs clean and very fun to shoot.
