  • Very Happy With It

    Very high quality. It fits well with my Aero upper. Feels good in my hand and looks even better. Worth every penny.

    Solid piece and looks great! But fitment was way off! I had to grind down the torque plate and the back of the handguard to make it fit right and tight. It would've been a 5 Star, but I had to put in some work to make it fit. I even called Rise Armament a week ago and left a message with no success in a return call from them. I do not recommend unless ur not afraid to do some grinding.

    Love the handguard, I'd give it 5 stars if it was $40 cheaper
