The BRP Corp Ultra High Precision (UHP) 15 was specifically made to meet our need for a rugged and precise lower receiver for our XMG Belt-Fed rifles. We hold half of the mil-spec tolerance to ensure exact fits and smooth function. These lower receivers are fully compatible with common AR parts and accessories.
These lower receivers are machined from forged 7075 aluminum blanks using only the best tooling available. We take our time making these and it shows in the quality of the machining. Not only are the milled slots and reamed holes precise, they are also clean and smooth. The internal machining is among the cleanest you will ever see in an AR-type rifle. Once machined and checked, our receivers are hard-coat anodized.
We have also included a set screw tightening feature at the rear lug area to eliminated any movement between the upper and lower assemblies. This is a useful feature for our XMG Belt-Fed rifles and precision shooters.
