The patented LMT Monolithic Rail Platform, MRP™ upper receiver.
The receiver and handguard are made from a single piece of aerospace grade aluminum.

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 MLOK 9.25 is the carbine length receiver designed for 10.5″ barrels up to 18″ barrels with M-LOK compatible attachment points on all 8 sides. This receiver sports 4 QD sling swivel attachment locations. Barrel not included.

Looks great and barrel dropped right in. This will couple with the lower I bought from Rooftop last month. Great service, fast shipping, and free ramen make Rooftop my go-to.
