I've had a lot of requests to review this set up over the years due to the price/value proposition. So, I threw some rounds to it and here's my thoughts:

Pros:
-cost
-7075-T6 upper/lower/receiver extension
-accuracy
-reliability to date
-nitrided 4150CMV barrel

Cons:
-no T marks on upper
-recoil impulse is a little bit of a "punch" rather than push
-barrel isn't MP/HP tested (at least not marked as such)
