Excellent bang for the buck - Magpul Industries AR15/M4 BEV Block

I just finished a complete upper build with this block and it worked out very well. It was well seated in the barrel extension and handled the torque wrench fine. The only reason I didn’t give it five stars is because my carrier didn’t fit over the o ring stabilizer easily, even after a little CLP. I had to tap my carrier with a rubber mallet to seat it and part of the o ring is no more. (What’s a knucklehead supposed to do?)
