The Diamondback Firearms DB15 Free Float M-LOK AR-15 Handguard is one of the easiest and most useful upgrades you can make to your standard M4 style rifle. The free float design and barrel nut attachment system is extremely rigid and ensures your handguard won’t rotate or move over time and keeps your iron sights zeroed. Additionally, the free float design prevents any accuracy anomalies from loading into your bipod or pressing your rifle against a barricade or any other task that—on a standard two-piece handguard—would impart pressure on your barrel and cause rounds to land somewhere you are not aiming. The DB15 free float handguard is forged from heavy duty and lightweight 7075-T6 aluminum and Mil-Spec hardcoat anodized for protection from corrosion and wear. In addition to the lightening cuts to reduce weight, the DB15 handguard features M-LOK attachment slots along 7 sides for ultimate versatility when customizing your rifle with accessories. The Diamondback Firearms DB15 M-LOK handguard comes with all the hardware you need to completely change your rifle setup.

Great option


This makes my AR15 build complete with a gritty look. If you’re looking for a simple 15in slim boy free float Maglock. This is the one.

Great value for the price


Food secure fit against the upper receiver. Solid barrel nut and clears the gas block without issue. Excellent no frills design

Great purchase.


Makes me wonder why other handguards are 2-3x as much. Good fit, nice finish and feels good on my rifle.

Low cost high value

Good fit and finish on this rugged handguard. Excellent for a duty rifle, a gun that will be used often. Nothing fancy, just a well made handguard.

Basic black and brilliant


Lined right up to the upper, fits well and does not move. Very nice finish for my Rosco Slimline barrel. Excellent lightweight combination. The textured ceracoat feels great in a working mans hands, there is no slip. *The manicured desk jockey may not care for this, however those who work with their hands and earn their living through hard work will appreciate this texture. The flat black is a nice compliment to the bead blast finish of Rosco Purebred Barrels.

7075 t6 is 7075 t6


This Mlok Handguard is lightweight as f***, fits perfectly snug to the barrel and M lok on all sides with a full pic rail on top. Just buy it. The quality is great
