MRP Upper Receiver | Ambidextrous Charging Handle |

16" 5.56×45 (.223) Chrome Lined 1:7" RH Twist Barrel

Utilizing the LMT® patented Monolithic Rail Platform, MRP™. The only true monolithic rail platform, milled from a single solid piece of aerospace aluminum forging. It utilizes two locking bolts accessible from the side of the receiver to lock in the barrel extension. This patented technology engages the barrel extension for a full 360 degrees around the extension and makes the barrel removable within seconds with a return to zero of the same barrel. One receiver can utilize numerous barrels of varying length, material, and caliber.

The upper receiver has 18.5" of uninterrupted 1913 picatinny rail on the 12 o’clock position. The remaining 7 sides provide M-LOK compatible attachment points.

Monolithic rail platform barrels utilize a low profile gas block and straight gas tube. They possess proprietary coating and are cryogenically treated for long term durability.

The MARS-L ambidextrous lower receiver features LMT® ergonomic textured grip and SOPMOD stock, and the ambidextrous features include bolt catch, magazine catch, and safety selector. As with all LMT® lower receivers, the extension tube is coated with dry film lubricant.

This weapon system comes complete with 3 grip panels, one magazine and owner’s manual.

The information below comes from our Gun Caliber Dictionary and is for general reference only. It does not describe the specifications of this particular item.

The 5.56X45mm NATO cartridge was designed by James Sullivan, a member of Eugene Stoner's engineering team that developed both the M16 rifle and its original cartridge. The 5.56X45mm NATO was adopted by the U.S. military in 1964 and by NATO in 1980. With bullet diameter of .224-inch, the original M193 military cartridge used a 55-grain bullet at 3250 fps; the current M855A1 cartridge, developed by FN, uses a 62.5-grain bullet at 3020 fps, offering greater range and better penetration. The civilian version of the 5.56X45mm is 223 Remington; the cartridges are dimensionally identical but military chamber dimensions and specifications for military brass are different. It is considered safe to use 223 Remington ammo in a 5.56X45MM NATO chamber, but not a good idea to use 5.56X45mm ammo in a rifle specifically chambered for the 223 Remington. Although the stopping power of .22-caliber bullets remains controversial the 5.56X45mm has served well in now multiple generations of M16 rifles. — Craig Boddington
