The patented LMT Monolithic Rail Platform, MRP™ upper receiver. The receiver and handguard are made from a single piece of forged aerospace aluminum. The barrel is held in place with a proprietary locking system that utilizes two locking bolts accessible from the right side of the receiver. The only tool needed is a standard T-30 Torx bit to tighten the bolts. This receiver requires the patented LMT monolithic barrel assembly which has a low profile gas block with straight gas tube.
The MRP-L 11.5" Quadwar Upper is a modified 13.25 Quadrail upper. We will take your supplied 13.25" quad upper and shortened to the same 11.5" length as Specwar upper.
We will clean up the cut end with a light chamber and apply Alum-a-black to the bare aluminum.
