Expert Review 5.56, eats everything well, became range invitee favorite - TRYBE Defense AR-15 16in 5.56x45mm NATO M-LOK Semi-Complete Upper Receiver

This upper is labeled #4 in a series of TRYBE builds. It's a basic 5.56 heavy barrel with with black nitride finish and A2 flash hider. I completed it with a TRYBE black chrome mil-spec BCG and TRYBE Magnite Charging handle. Those reviews are elsewhere. The whole package became a favorite of my range invitees because of the 1-8 TRYBE SLED scope on it and a TRYBE Enhancer on it. If you think this is kind of a TRYBE commercial, you're right. I like the stuff.
The #4 gun became a range favorite for new and newer shooters because the scope attracted them to it, not necessarily the gun. BUT, that's a pretty good thing, because the gun did what it was supposed to do: go bang when you pull the trigger, shoot a bullet consistently, and not burp in class.
I cleaned it out of the box and it needed it. I did not break it in or try to break it, but had 5 or 6 extended range sessions with it with a decent cleaning between rounds. I always use a bore guide and good equipment, never overlooking chamber cleaning and wet lubrication rather than not. The barrel has cleaned easily and may has a couple thousand rounds through it by now by a variety of people.
This #4 has eaten everything I've given it and I've been feeding it partial boxes of fodder to make room in the shop, but mostly bulk green tip and XM193. Not accuracy loads for sure, but this does shoot everything I've put in it well.
No issues, good basic upper.
