  1. R

    I’d you would like to have a SBR without spending upwards of $1400…this is the perfect application

  2. AH

    Fit the G3 perfectly.

  3. DP

    First impressions were good. Out of the box seemed rugged and well made. Fit up was perfect for my M&P 9 and was able to put 250 rounds through it and all I can say is WOW. No issues whatsoever and the dramatic increase in accuracy makes this package well worth it in my opinion. Drills holes in the targets. Certainly can’t ignore the fact that it is also a blast to shoot. Lots of fun! The additional components are also of good quality. I wouldn’t hesitate to recommend these to anyone.

  4. JH

    Don’t care for the thumb rests. My grip felt better without them off.
