This is where you use your 'estimation'. There will be a small gap (mm+) between HG and upper continuous rail. I found out you'll have problems with tolerances around your takedown pin space. Do not thread HG against upper receiver, even if it fits perfect.

Screw the handguard lock ring (threaded outside the bbl nut) full rearward toward the upper receiver to keep out of the way during HG install. I used 1 drop blue loctite on handguard threads. Handguard screws on to barrel nut (lots of threads). Remove the handguard set screw at the bottom rear rail.

Install barrel nut/gas block&tube according to standard rules You will need a strap wrench (cloth one is best). So I thought to mention that (I have to remove 4 crush washers - my poor planning). THESE MUST BE INSTALLED BEFORE THE MUZZLE. They attach to the open end of the rail with 4 tapered screws (to prevent things from getting into the handguard area - if you desire), and the caps have 2 small set screw against the barrel. If you want them, ohhunts makes and sells them too. Mid $300's for 10 free float handguards.īear in mind these are set up to receive the rail end caps. But the tubes all passed through and everything seats fine. The ONLY thing I found was a slight variance in the HEIGHT of the gas tube holes when torquing (the gas tube would tap the receiver entrance on the top side (I have a cheap flex video scope). Only thing is there is no instruction - though I watched an identical handguard install online (same mfr I presume). Finding these was an unexpected surprise.

I had inadvertently bought barrels with dedicated pinned low pro gas blocks, making free float a necessity. I think they may just keep these, unless very particular. Trying to keep the investment as small as possible (when sold, new owners will customize every part to their favor). The price for these rails is outstanding. At the time of this review I have all the ohhunt barrel nuts installed and 4 of the handguards.

Attaching accessories to drop-in type handguards may cause destabilization while firing, the same is not true for free float types. Free-Floating HandguardsĪdvantages of free float handguards include increased stability, accuracy, tactical flexibility, and overall aesthetic. As an open-sourced design, the entire firearm industry is free to use and distribute KeyMod rails in the public domain. The “key” related to the keyhole profile of the rail, and the “mod” referred to the modular accessibility of the rail. The term “KeyMod” was coined by Eric Kincel when he worked for VLTOR Weapon Systems. KeyMod Rail SystemĪs a universal interface system for firearm accessories, the KeyMod rail was designed to supersede the MIL-STD-1913 rail. The KeyMod Handguard was designed by specialists who created a piece that offers long-lasting durability because of their experience. Available in Black or Raw Aluminum, the Handguard features a secure fit and the ability to provide an unyielding grip.
