The Crye precision MRB (Modular Rigger’s Belt) is a single, lightweight belt system that features a LoopLock inner belt layer that passes through pants belt loops, keeping the MRB oriented and stable.
With multiple pistol mounting options (on inner LoopLockâ„¢ layer, on exterior MOLLE sleeve, and on main belt) the main belt can be replaced with alternate load-rated rigger’s belts. Ergonomically-shaped for long wearing comfort and extremely light and low bulk, the MOLLE sleeve has an opening for drop-leg holster integration. The inner LoopLock belt functions on its own as a great low-profile pants belt (no bulky hardware). Made in the USA from US materials.
