The UTG PRO M-LOK Arca Rail is a compact, high-quality component crafted in the USA from 7075-T6 aluminum, offering strength and lightweight performance. Its slim profile is contoured to reduce snagging and discomfort when shooting from unsupported positions. Designed with an M-LOK interface, it can be mounted in either full slots or between adjacent ones. Laser-engraved positional indicator markings make repeatable placement easier. When multiple rails are used together they form a continuous ARCA platform, compatible with standard ARCA, R-LOCK, and MRAS quick-detach adapters, giving flexibility for mounting accessories.
