Presma AR-15 Split-Top M-LOK Handguard

AR 15, 10" length free float rail mount with partial Picatinny Top rail and M-LOK slot system.  Steel barrel nut included.  CNC machined from Quality aluminum and black anodized. Super lightweight, only 11oz with barrel nut.

A true free float rail, which connects only at the Steel barrel nut. Since the rail doesn't touch the barrel, shooting accuracy is improved compared to two-piece rails when used with grips/bipods that can flex the Steel barrel.
Includes steel barrel nut, screws, (2) shim rings for barrel nut timing, (2) 3 slot M-LOK rail segments, (2) 7 slot M-LOK rail segments, and M-LOK screw set.

I.D. - There are small reinforcement ridges inside.  Ridge to ridge I.D. is 1.28".  Interior wall to wall I.D. is 1.45"

These will fit AR-15 uppers.  Therefore, they will also fit AR Pistol builds that have AR-15 upper barrel nut threading, such as the 300 Blackout and the AR-9.
