Midwest PX Premium Billet AR15 Lower Receiver Gen1
Our premium billet receiver is manufactured for us by a contract machine shop in the US. All operations are performed under one roof to ensure a quality product prior to being sent out for milspec plating. These receiver are made of 7075 billet aluminum which is significantly stronger than 6061. We have a number of extras and upgrades built into this lower such as the threaded bolt catch pin, threaded takedown detent hole, and upper/lower tensioning screw. All hardware to take advantage of these features are provided with each lower at no additional charge. We also opted for a subdued rollmark for a cleaner, more aesthetically-pleasing look. Our name and location are on the side...we know it's our lower, we don't need a huge engraving further telling us that :)
As with all Midwest PX branded parts, this lower carries a lifetime warranty against defects in materials and workmanship.
Save on your build by bundling our LTG LPK and milspec receiver extension kit (carbine weight buffer, milspec diameter extension, action spring, end plate, and castle nut) with your lower! Save up to $13 over regular price when purchasing these items with the dropdown boxes below vs. adding them to the cart separately!
