5 of 5 Good product April 4, 2019
: David Swartwood from Devine, TX United States  
So far I'm happy with new 9mm upper.  Haven't shot it yet but it seems great.

The keymod rails that came with the upper (free add on so I know I shouldn't complain) are too long to fit that short of an upper.  Not a big deal but I'll have to go buy some shorter rail sections.

MasDefense 4.75 w/Kaw compensator, SpringCo Red spring buffer, PSA H2 buffer, American Resistance AR-9 BCG (fostech compatible), fostech eco-ARII -- and it works through 9mm ammo like an angry sewing machine! (NOTE: I had a heavier buffer and it failed to eject => switch to an H2...never looked back). « less
