Bought this in 2021. Out the box, would not chamber or fire. Sent upper back twice. Still jammed. Have put about a thousand rounds through it so far. Runs better now. Still wont unload a full 30 round clip without at least 2 or more jams. Would love for them to take it back to see if they could tweak it a little more. But over all, high quality upper, just not sure why it wont run as fast and smooth as it should.

Dear James. Happy to look at it again. But perhaps before all, try to enhance your BCG with enhanced 7.62 firing pin and your lower with Wolff heavy spring. That shall address most of your concerns. Thank you!

Not happy with the muzzle brake! I’m currently trying find someone who can tack Weld it to the barrel. Other then that it works great.

Only ran about 50 rounds thru it but I’ve had zero issues and just love it. Highly recommend!!

What else is required to complete this besides a fully assembled AR-15 lower

____

BCG and CH

All in all I like the feel and the look . Works great with brass ammo just like Moriarti suggested, hates steel. Lol
