LMT Defense 16" MRP Piston Complete Upper Receiver Bundle BFCLMT-16

The LMT Defense 5.56mm 16" Piston MRP Barrel Assembly (L7PC1B) is a 16-inch chrome lined 5.56×45 (.223) barrel featuring LMT's short-stroke piston operating system — the key upgrade for shooters who demand reduced fouling, cooler operating temperatures, and enhanced reliability in adverse conditions. This barrel sports a 1:7" right-hand rifling twist and A2 birdcage flash hider, coated and cryogenically treated for maximum long-term durability.

The LMT Defense MRP-L M-LOK 9.25" AR15 Upper Receiver (L7X1A) features the patented LMT Monolithic Rail Platform (MRP™) — the upper receiver and handguard are machined from a single piece of forged aerospace-grade aluminum, eliminating flex and providing an unrivaled platform for accessories and optics. The MRP-L MLOK 9.25" is the carbine-length receiver designed for 10.5" to 16" barrels. Features M-LOK-compatible attachment points on all 8 sides for maximum accessory versatility, plus 4 QD sling swivel attachment locations for flexible sling configurations. The compact 9.25" length keeps the overall profile tight without sacrificing rail space.

The LMT Defense Ambidextrous 5.56 Charging Handle (R-LMP103TA) features enhanced tactical latches on both sides for true ambidextrous operation. Dead-stop latches reduce tension on latch pins, extending service life while allowing fast, positive manipulation from either hand. This is standard operating equipment for the New Zealand Defence Force and countless law enforcement agencies worldwide.
