The good and the less good... - TRYBE Defense AR-15 10.5in .300 Blackout M-LOK Complete Upper Receiver

Okay, for a rock bottom budget priced complete upper receiver inclusive of a bolt carrier group and charging handle, this is one solid deal! A close shooting buddy and I purchased this Trybe upper and we both discovered that, at the ranges most suitable for using a 10-1/2" barreled pistol in 300 Blk-Out this is a very accurate shooting system! We saw group sizes out to 50 yards that were less than one MOA using both subsonic and supersonic ammo!
However, is it without some cost cutting compromises? Well, no, there are some aspects that may cause some to whine and moan. Like the way the free floated hand guard is attached... There are three screws that secure the hand guard to the barrel nut two of which provide a squeezing action, and one that cinches down on a groove in the barrel nut. This third screw causes the hand guard to deflect downward, unless it is tightened at no more than just touching the barrel nut. Both of our examples were out of alignment by almost 1/4" as delivered. Loosening all three screws and realigning the hand guard as well as the addition of a drop of low strength thread locker did put this problem right.
Additionally, you'll likely want to replace the semi-birdcage flash hider with a blast can of some sort (or a suppressor) as the concussion from some of the supersonic ammunition will very assuredly clear your sinuses and get everyone's immediate and unwanted attention at the range!
As to fit and finish, both of our uppers were very snug when mated to Anderson lowers and the finish was a perfect match!
All and all, the Trybe 300 Blk-Out upper is, in my opinion very tough to beat at just over 3 C-Notes! If your budget for a 300 B.O upper is tight, this the deal you've been searching for.
