Great So Far
So far the upper has worked well, I've only ran a little over 100 rounds through it with no issues. Only time will tell. So far well worth the money.

Fun and punchy
Loving this little "toy". I had to use a lighter buffer spring in my PSA pistol lower to get it to cycle the Hornady Black ss. Sig ss worked beautifully without modifications.
