Frequently Asked Questions

Does this rail lock in place, or just use friction like a standard ARCA rail? It mechanically locks in place when paired with an Area 419 clamp; without that clamp it functions as a standard ARCA-compatible rail.

How many M-LOK slots does it need? 6 consecutive M-LOK slots; for handguards with fewer slots, Area 419 offers a 12-inch universal rail with attachment nuts instead.
