What handguards fit my gun?

Our Mk4 handguards along with any freefloating AR15 type handguard should work on our Mk4, Mk9, MkG, MkGs, Mk17, Mk10, and Mk57 lines as the upper receivers are based off a standard Mil-Spec upper receiver.

Our Mk3 handguard along with any freefloating handguards compatible with DPMS Gen 1 LR-308 High Pattern uppers/rifles should work on our Mk3 and Mk47 platforms.

Please note. While our Mk4 upper receivers are made based off mil-spec dimensions and our Mk3 uppers are based on DPMS High Pattern,  the geometry and aesthetics of our designs may not be compatible with handguards that have alignment tabs that extend to the sides of the upper receiver.
