Great 9mm conversion. A must for an AR owner who wants to shoot and train with cheaper ammo
by Barry -
Works as advertised, just follow instruction for lower install( Literally installs less than two minutes and comes off less than that). Ran with my few KCI mags and ran with no problem and BHO worked. Occasionally bolt will not hold open but narrowed it down to the same glock magazine(gen 3). Used with a FM 16” upper with red dot combo (Kit-FM16-9MM-3-MB-MD-RBGII) and ran great. For some reason Glock gen 4 mags will not drop free but my old KCI will( I got lucky).Lefty here so mag release works out to my advantage. A bit pricey but cheaper than getting a dedicated lower and have it registered.
