Review by Christopher L. on 25 Sep 2024review stating Awesome handguard!!!
Installed the 15" Urban Combat rail on a 16" M&P 15. Along with Superlative Arms adjustable .750" clamp on gas block, rail clearance is a go. Looks amazing, feels great in hand, fits tight, straight, and easy to install. Rainier as always great service and fast shipping.

Look and feels great the design is nice and the cuts are clean. I will say the 15” rail feels a little heavier on the rifle than I wanted but still exactly what I was looking for
Q: Will this 9.5” handguard work with the 10” ultra match Rainier Arms 300blk barrel or is it too long?

Q: I am wanting to put these over a Superlative Arms carbine length piston kit and I'm would like to know if it will fit. I'm new to this game so forgive me if this is a dumb question.
