Great quality hands down will be a return customer.

I have only fired 30 rounds through it so far but it has performed flawlessly. I tightened the screws on the gas block and the handguard and I used a PSA bolt. Not a single issue. I am impressed with how light this upper is.

Built a 300 blk pistol, but even with reloading it's expensive to shoot often. Recognizing its a cheap barrel and .223 loses a lot of velocity out of a short barrel. But I've found I carry this setup the most often in a vehicle. It's not a hunting gun or even great self defense, but certainly better than a .22 and more maneuverable than a rifle. Primarily for training, but has become my most available option. Kids really like it, but make sure you have good hearing protection as it has muzzle blast. Has shot 50-75 grain ammo out to 200 yds fine. There will always be ammo available. Quick shipping.
