SKU: N/A Category:

AR15 Cornerstone series handguard (standard or competition) in black hard coat anodize.

Our AR-chitect AR15 CORNERSTONE SERIES hand guards are designed to be slim and light.
A low cost alternative to foreign sourced hand guards. American made quality at an import price.
An overall width of 1.5 inches and a weight of only 9.5 ozs. for the 15 inch model provide ultimate comfort.

A 1.3 inch I.D. will accommodate most low-profile gas blocks. (we have seen some interference with some clamp-on style low profile gas blocks)

MLOK slots at the 3,6 and 9 positions are manufactured to MAGPUL standards to ensure proper fitment with any MAGPUL certified accessories.

Every handguard comes with a 4140 pre-heat treated steel barrel nut that has been black nitride coated not phosphate coated. All mounting hardware is included with full mounting instructions.

A two-inch-long barrel nut ensures rigid mounting for rock-solid accessory mounting. ( this system will not work with piston-driven rifles)

American made from American sourced 6061 T-6 extruded aluminum.

Available in hard-coat black anodize or in the bright.
Hard-coat anodized in accordance with MIL-A-8625 Type III class II.
100% warranty against any and all manufacturers defects. If we missed something we will replace it at no cost to you.
