Great fun
I ordered the upper on Wednesday and received it on Monday. Took it out to the range and had a great time with it. First three rounds the BCG was very tight and I had to use the charging handle to eject and chamber the next round. After the third round it worked on it own and I when through three 25 round magazines without any problems. This upper is an exact match to the 5.56 and 7.62 uppers I got from PSA and I have not had a problem with any of them.
The .22lr upper will allow me more range time as it is about 1/10 the cost of 5.56 and 7.62.

Nicely made upper
Purchased this upper to go with my 80% lower build and a PSA lower parts kit, ran flawless with minimal cleaning using quality ammo.
