AR-15/M16 MODULAR UPPER RECEIVER Reviews & Ratings

The MUR is a flattop upper receiver with thicker walls than a standard upper to provide a more rigid platform for greater stability, better accuracy, longer service life, and improved reliability. Precision machined from a fully heat-treated and cryogenically stress-relieved aluminum forging, before hand finishing to final dimensions. All critical interface points are 100% compatible with mil-spec select-fire AR-15/M16/M4 components and lower receivers, and will fit most commercial semi-auto lowers. A slick, dry-lube coating over the hard-anodized finish further guards against surface wear and helps ensure smooth operation of bolt/carrier and other internal components. Comes with true MIL-STD 1913 Picatinny rail with 13 cross-slots, plus forward assist and ejection port door pre-installed. Gunsmith installation recommended. Includes M4-type feed cuts. Available with or without forward assist.

SPECS: 7075 T6 aluminum, Type III, Class 2 hardcoat anodized, dry lube coating, matte black. .250" dia. pivot/takedown pin holes.

Very Disappointed

Very Very disappointed. I spent a year specifically researching and buying part by part to build my AR-15. I thought, "no problem" the Vltor MUR w/Forward Assist would be great between my LaRue handguard and Spike's Tactical Zombie lower. And a nickel boron bolt carrier would work so smoothly with all these. Well apparently Not. After finally putting together all the pieces the great day came to go to the range and test everything. After less than 140 rounds of PMC 55grain .223 and Remington 55grain .223 The FORWARD ASSIST LITERALLY FELL OFF. I couldn't believe what had just happened, the Forward Assist is held onto the MUR with one of the smallest pins I've ever seen. And in less than 140 rounds it sherd apart. I'm already looking into replacing this Upper with a different. BE WARNED of the Poor Quality and Flimsy Design of the Vltor MUR.
