COMPETITION RAILS WILL BE IN STOCK END OF OCTOBER
AR-15 Cornerstone series hand guard (standard or competition) in black hard coat anodize.
Standards come with a full length picatinny rail the whole length of rail.
Competitions come with a cut a way picatinny rail and clamping lugs only a the front and rear of rails.
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)
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)
