Looks great, function well. February 24, 2016
Reviewer: Anonymous Person from Dublin, CA United States  
Finally got a chance to shoot with this upper.  Fits perfect with my M&P Lower.  No issue with 100 rounds of Russian ammo. The floating grip did come loose after the first 100 rounds but nothing that a Loctite can't fix.

Great Product January 21, 2016
Reviewer: Ted from Pasco, WA United States  
Fit tightly on my Anderson complete lower.  I took it to the range with some steel cased Russian 123gr FMJ rounds and didn't have a single issue with the 100 shots I put through it (using CPD magazines).  It's relatively light.  It's an incredible value.
