Arisaka Defense Low Profile Picatinny Rails for M-Lok

The Arisaka Low Profile Picatinny Rail is a 5 or 3 slot Picatinny rail for M-Lok handguard systems. It offers a reduced height to pull any Picatinny accessories closer to the handguard. The 5 slot model connects with three of Magpul's M-Lok nuts which will spread the increased stress of large Picatinny accessories like bipods or vertical grips over more M-Lok slots. The 3 slot version is useful when less rail space is required.

Picatinny slots: 5 or 3

Height over mounting surface: 0.277"

Length: 2.15" (5 slot), 1.37" (3 slot)

Weight: 0.7 oz (5 slot), 0.4 oz (3 slot)

The Low Profile Picatinny Rail is CNC machined from 6061 aluminum and MIL-A-8625 Type III hard coat anodized. Requires a 1/8" Allen wrench for installation (not included). Our M-Lok nuts are manufactured by Magpul. Made in the USA.

    I needed a low profile rail for my Ruger PC Carbine and this one was perfect. Great for mounting my front iron sight
