Dirty Bird SMRS Slim M-LOK Handguard 13.5" Magpul FDE

Dirty Bird AR-15 SMRS Handguard - Slim M-LOK Rail System The SMRS (Slim M-LOK Rail System) by Dirty Bird Industries is a high quality and feature packed M-LOK hanguard designed for AR15 platform rifles and pistols. When designing this handguard, the team started from a basic set of requirements: The handguard must be tough, versatile, practical and have a straight forward install. Tough Machined from aircraft grade 6061-T6 aluminum extrusions. Anti-rotation tabs. Type 3 hard anodizing or Cerakote(TM) sprayed at 1 mil thickness per spec. Versatile M-LOK attachment slots on all sides (except top) 1913 Picatinny top rail with shaved and beveled center section. Raised QD attachment points at the 3 and 9 o'clock positions. Snag free design with smooth, uniform octagonal surface ideal for accessory attachment or application of specialty coatings or patterns. Practical No extraneous cuts in the aluminum simply for the sake of weight savings or enhanced visual appearance. Aircraft Grade aluminum barrel nut. In our tests, the aluminum barrel nuts are just as effective when torqued to spec. Additionally, the weight savings enable us to utilize a longer barrel nut design which means more surface area at the attachment point without adding unnecessary weight. Compatible with most known low profile gas blocks. Straight Forward Installation No frills clamp-on style installation using only a 1-3/16 Crow's Foot wrench and 5/32" Allen key Barrel nut does not requiring timing with the gas tube. No shims required. The end result is a great looking, zero compromise handguard suitable for a wide variety of builds.
