AR-15 M-LOK Handguard


More versatile than a Swiss army knife — and nearly as light — the RISE Armament RA-905 AR-15 Handguard combines all the features you want in a handguard. Durable yet lightweight, it is M-LOK compatible with a Picatinny upper rail. It even boasts six quick-disconnect mounting points. The points span 360 degrees around the handguard for maximum customization. The slip-on handguard is simple to install, while its free-floating design helps increase accuracy.

Terrific Handguard – Excellent Customer Service

This is my second Rise Armament handguard. The quality on both is second to none. I did have a problem with this one because the spacer that locks it to the barrel nut was out of spec. I called customer service and spoke to Ty. He agreed things didn’t look right and took the issue to their production manager who found more out of spec examples. Here’s where things get awesome: Ty told me they were going to mill a new part for me, Cerakote it and ship it out, just to be sure! Oh, and would you wear one of our hats or a t-shirt? Hell, yeah! Proudly! I’ve been a fan of RA’s triggers from day one, but now I’m a fan of the company. Well done, guys!
