The MRP(Monolithic Rail Platform)is a true monolithic rail platform and is machined from a single aluminum forging. It utilizes two locking bolts to lock the proprietary barrel in place. This patented design engages the barrel extension for a full 360 degrees while allowing for easy removal with return to zero of the same barrel.
The LMT MARS-L lower receiver features ambidextrous controls including the bolt catch, magazine catch and safety selector.
This model uses the MRP-L "Specwar" 11.5" M-LOK upper with a 12.5" barrel configuration.
