Description
Dirty Bird AR-10 SMRS Handguard – Slim M-LOK Rail SystemrThe Dirty Bird AR-10 Handguard is our first Free-Floating M-LOK Rail for the AR-10 platform. We took the best functions of our AR-15 Handguards and created an AR-10 rail that we feel is tough, versatile, practical and economical, meant to be used on any build. The SMRS (Slim M-LOK Rail System) by Dirty Bird Industries is a high quality and feature packed M-LOK handguard designed for AR-10 platform rifles and pistols.rToughrrMachined from aircraft grade 6061-T6 aluminum extrusions.rType 3 hard anodizing or Cerakoteâ„¢ sprayed at 1 mil thickness per spec.rrVersatilerrM-LOK attachment slots on all sides, and lightening cuts on shaved portion of the top rail.r1913 Picatinny top rail withshavedand beveled center section.rSnag free design with smooth, uniform octagonal surface ideal for accessory attachment or application of specialty coatings or patterns.rrPracticalrrThis version featuresthe patent pending anti-slip / anti-lift attachment method (ASALTM) for an easy, timing-free installation that providesan extremely rigid and secure attachment.Read below for more technical details about thisimpressive new attachment method.rCompatible with most known low profile gas blocks.rrID of Handguard: 1.5535″rOD of Handguard: 1.76″ wide and 2.20″ tallrThe end result is a great looking, zero compromise handguard suitable for a wide variety of builds.rIncludes QD mount, but will not come with a barrel nut wrench.

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.rHandguard LiftrFree-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.rSolutionrThe 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 ASALTMsystem locks the handguard to the barrel nut using a CamLokTMfastener 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.rThe result is a 10x decreases of handguard muzzle end lift.
