FightLite Industries’ MCR-060 claims to be the lightest belt-fed upper receiver assembly, and it’s also simple to use. The MCR (Mission Configurable Rifle) will fit any AR15, M16, or M4 lower receiver. It’s chambered for 5.56 x 45mm NATO rounds. It is compatible with all AR15 and M16 magazines as well as M27 linked ammunition–but maybe not at the same time.
The MCR-060 is compatible with fully automatic lowers. Feed it a belt, and it’ll keep eating until you take three seconds to change the barrel.
Are you worried that the 16.25″, 1:7 righthand twist chrome lined barrel with 1/2″-28 threading can’t take the heat generated from belt-feeding this gas piston-driven little monster? Don’t sweat it: you can swap out the barrel in as little as 3 seconds so you’ll have minimal interruption to your shooting spree.
The receiver is precision milled from a billet of 7075-T6 aluminum, as are the feed cover and charging handle. The feed tray is milled from a solid billet of steel. This upper is solid and made to last.
A billet is a solid piece of metal, and this receiver is milled from a billet of 7075-T6 aluminum while the feed tray is milled from steel.
The MCR-060 upper costs $4,414.
Although it can take a belt of ammo, the MCR-060 is not too big to wield hand-held.
But, there’s also the MCR-060S. This Short version drops the barrel to just 12.5 inches but keeps all the other features, as well as the same price.
The MCR-060 comes with iron sights and rails ready for optics, but you don’t want the included iron sights, the MCR-036 and MCR-036S ship with the rails only and cost just $3,822.
The MCR-060 comes with iron sights, but you can also get the MCR-036 without sights.
If you don’t have an empty lower laying around to drop this bad boy onto, FightLite Industries would be happy to supply you a complete MCR-100 for $5,260, which weighs in at just 9.75 pounds.
FightLite would be happy to equip you with a complete rifle, the MCR-100.
