Xtreme Machining began production of AR-style semi-automatic rifles in 2009. As with all of our products, our goal was to manufacture a rifle offering excellent accuracy, total reliability, long-term durability, precision in fit and finish, and high value for the money. Our AR-style rifles are made to stringent military specifications, with both upper and lower receivers CNC-machined from 7075 T6 forgings, stainless-steel and chrome-moly cut-rifled barrels, and mil-spec internal components, all made in our Pennsyalvania manufacturing facilities.

We make two XR-15 models. Our Basic XR is perfect for general shooting, home defense, and law enforcement, with a 16 ¼” barrel cut-rifled in a 1:7” twist, M3-type flattop upper receiver, quad-rail free-floating fore-end, quad gas block with top Picatinny rail, and collapsible buttstock. Each rifle comes with two AD Ops 30-round magazines. Detachable front and rear iron sights are available as an option. Even though this is the most economical AR we build, it still offers complete reliability and sub-m.o.a. accuracy with the proper ammunition. And, because it is made to military specifications, it will accept virtually all aftermarket AR components.
