The continuous top rail allows you to mount iron sights, optics and any other accessories without additional rail sections. The Magpul M-Lok system allows users to customize the hand guard with rail sections and direct mount accessories. The hand guard is constructed of 6061-T6 aircraft aluminum and finished with a Mil-Spec type III hard coat black anodizing.
The MLA has a precision bore to fit the proprietary barrel nut which removes any unwanted play and ensures an exact fit!! Installation requires a 1-1/8" crows foot wrench (not included) for the barrel nut; standard AR-15 barrel nut wrenches will not work with this hand guard system. The hand guard is secured to the barrel nut by 2 10/32 allen screws, stainless steel key seat lock, and anti-slip helicoils.

The thing I like the most from the install side is the barrel nut there is no need to line up the hole for the gas tube just torque down and go. Very nice finnish and machining. Great rail

Nice job. I am a machinist myself and take pride in all my work. You can see they take pride in what they do.

Just got the 13" angled m lok handguard in. Shipping was very fast. Thing is awesome looking and unbelievably light in the hand. Looking forward to getting it on my rifle. Had one very small spot that appears to be chipped down to metal, but other than that, its phenominal.

I was looking to downsize my quad rail for a lower profile rail system. The 13" JL Billet M-Lok rail was the perfect answer. I looked around for 6 months and compared every rail imaginable. JL was the best option for me. It was extremely simple to install and JL customer service was very helpful in providing me information before my purchase.

Absolutely love this handguard! Extremely light and looks perfect on a 16" barrel. Fit and finnish is sport on. Will buy again for future builds. Just an FYI if you don't own a 1-1/8 crowfoot , don't buy Sunex. They are too thick to fit in the groves of the barrel nut.

Awesome, lightweight free-float rail. Secure and stable mounting with an extended top rail. Great looking design.
