I sighted one in for my neighbor and put maybe 200 rounds through it. Pretty accurate but it was acting funny when I put my Mystic can on there and shot the 147 gr subsonic federals. Wouldn’t cycle. The magazine release is in an odd spot too; easy to accidentally drop the clip. Agree with the other post that it’s a bit heavy too.
Not saying that you shouldn’t buy one, but I’d think more about the 5.56... cheaper ammo, longer range, more options. You can get a 300 BLK upper if you wanted a subsonic thumper too.
Since moving back to NY I've been using one for the HD gun since I can't have my pistols or ARs here. Shoots really well and is very accurate. There are some modifications I'd like to make, such as adding a light and red dot. Definitely worth a look.
I have the Mlock version. I like it, built very well, reliable but as mentioned, it’s a bit heavy. Still glad I bought it. I have a Vortex Venom 3moa on it.
