Solid Rail, Unbeatable Price
This rail is exceptional. Made of the same trusted materials as other, higher dollar handguards and utilizes the same barrel mounting process with a steel barrel nut. Aesthetically pleasing, functional, and just the right size for a 20” barrel while covering a low profile gas block completely.
USMade my Meh M&P sexy.
Easy installation and fast shipping.I will order again! I wish I could live there.
USFitnFinish2
What a steal for your next pistol build. Excited to run it hard and see just how far it'll take me. Top rail seamlessly flows with the NBS upper receiver that was purchased with it. Needless to say can't wait to get it painted and all put together. Service was top tier and shipping was fast. Will definitely come here first for my next build.
Better than the manufacturer
This has a very solid fit and was installed by a gunsmith. The finish and rail has held up under normal use. I’m don’t throw my firearms around, so I can only speak to “normal”use. I’m totally please and it’s better than what came on the new rifle.
USSolid Handguard
Fits and feels great. Really easy to attach and it doesn’t move at all
