In stock
The NBS AR-10 Free Float M-LOK Handguard is the perfect addition for your next AR-10 build. This LR-308 handguard features a high-profile DPMS design to be compatible with most other high profile AR-10 upper receivers. Our NBS 15″ AR 10 handguard features a monolithic top rail and the remaining 7 sides all feature M-LOK attachment slots. Precision machined from 6061-T6 aluminum extrusions then type 3 hard coat anodized you can be sure that this handguard can withstand an incredible amount of abuse. Its slim profile feels great in the hand yet and can accommodate any true low profile gas block and even has enough clearance to recess some muzzle devices such as flash cans and linear compensators. It is a true do-anything rail system and the cost-value ratio makes it very hard to pass-up.

ASAL Attachment System Report
Eliminating Handguard Slip
The shockwave generated when firing an AR-15 creates over 1000 G’s of acceleration. This means that a one pound part will generate over 1000 pounds of force every time the rifle is fired. Combined with the thermal cycling generated when firing multiple rounds, it can be very difficult to keep a handguard from slipping forward or rotating. Many attempts have been made to solve this problem. Some solutions are overly complex, resulting in difficult installation and high manufacturing cost. Some designs, like the popular key seat, are overly simple. The key seat will stop a handguard from coming completely off of the rifle; however, it still allows some forward slip and 360 degrees of rotation.
Handguard Lift
Free-floating handguard mounting systems tend to produce an upward lift of the handguard, resulting in the muzzle end of the handguard floating higher than the receiver end. This lift can adversely affect the performance of the rifle, especially when using iron sights. Even if the handguard is only used for protecting your hand, a small amount of lift is noticeable when aiming down the sightline. This visually makes the rifle seem crooked. Even if the rifle performs with precision, it can create an optical illusion, thereby reducing accuracy.
Solution
The patent pending ASALTM (Anti-Slip / Anti-Lift) system is simple, easy to install, easy to manufacture, and a cost effective solution to handguard slip and lift issues. The ASALTM system locks the handguard to the barrel nut using a CamLokTM fastener featuring a 10 degree taper angle. This small taper creates a huge mechanical advantage, greatly increasing the force generated by a standard screw. The mating groove in the barrel nut is offset so as it is tightened, the handguard is pressed against the upper. This mitigates lift while also preventing slipping or rotation around the barrel’s axis. The result is a handguard that will not slip, rotate, or lift.
The result is a 10x decreases of handguard muzzle end lift.

USPalmetto State Gen 1 DPMS High fit problem
This handguard is supposed to fit the DPMS "High" upper receiver but it does not. I've measured the tail over the charging handle on my upper, it measures 0.1875" as opposed to 0.125", so it's verified as a "High" DPMS upper. The problem is that the Picatinny rail on the handguard sticks up higher than the Picatinny rail on my upper (see picture), so it's not a match. That sucks, because otherwise, this handguard is great -- the anodizing matches my receiver very well, the handguard locks up extremely well with the ASAL system, the price is excellent for the quality of the workmanship, etc. In short, if the Picatinny rail height matched, this would be the perfect handguard to put on my AR10.
