The Presma M-LOK to ARCA rail adapter attaches to the standard M-LOK slots on your handguard and gives you an ARCA rail for tripods, bipods and other ARCA-compatible gear. It also accepts R-LOCK and MRAS QD adapter mounts.
The rail is machined from 6061-T6 aluminum and anodized for durability and wear resistance. It is offered in multiple lengths, so you can pick a short rail for a bipod mount or a longer one that lets you slide the rifle fore and aft in a tripod clamp to find balance.
Line up the rail with an open run of M-LOK slots, turn the nuts into position and snug the screws evenly. Recheck the screws after your first range session, since a loose rail will shift your rifle in the clamp.
