Most Recent Reviews Great look installation could use some updating by Ace, Verified Owner, July 12, 2021
I purchased this 7.5" handguard for a AR pistol build. The 'S' cuts are good looking. The finish is good quality, however this add-on came with zero instructions. Timing the barrel nut with the gas tube wasnt a pain, but there are plenty of other aft...

Product Info for Obsidian Arms S-Pattern Handguard, M-LOK

The M-LOK handguard by Obsidian Arms will do more than just protect your hands from the heat of the barrel. The lightweight free float system is equipped with a variety of attachment options so you can mount whatever accessories you need. These options include a Picatinny rail running along the top, M-LOK slot cuts along the sides and bottom, and S-pattern cuts in between the 3, 6, 9, and 12-o'clock positions.image

The big sell for the Obsidian Arms handguard is, of course, the M-LOK system. While a full-length rail will provide plenty of space for mounting gear, some might see it as too much. The excess rail adds unnecessary weight. The genius of the M-LOK system is it allows you to build just enough rail. Without excess material on the rifle, you will have an easier time keeping your AR lightweight.

Additionally, the AR 15 M-LOK handguard was constructed from 6061-T6 aluminum and black hard coat anodized, and it comes with a steel barrel nut. It's also available in a variety of lengths and color options. Buy AR Handguards & Forends by Obsidian to upgrade your rifle today!
