Clear all options to re-configure

Like many good ideas (debatable…), the ORW-15 was conceived around a campfire with frosty beverages in hand. We spent a lot of time custom building AR rifles for our customers and noticed that based on our recommendations, user feedback & performance, we were building the same gun over and over. With the help of our friends who own a high-end custom machine shop, the ORW-15 was born. What started off as a fun side-project, morphed into a full-blown rifle program.

“Why not start a line of AR rifles…” – good buddy around the campfire

The ORW-15 is Oregon Rifleworks’ premier line of firearms. Built around a 416R SS barrel chambered in .223 Wylde, it hosts a mid-length gas system (14.5″ & 16″ lengths) that provides smooth and reliable cycling and reduces wear on moving parts. The 18″ models utilize rifle-length gas systems while the 10.3″ and 11.5″ pistols are configured with carbine-length gas systems. The billet upper and lower receiver blend seamlessly together, and paired with our full-length M-LOK handguard, feature an uninterrupted 1913 Picatinny rail on top. the ORW-15 has plenty of real estate for any sights, optics, and accessories the end-user may require. 

Each ORW-15 is assembled by hand, one at a time, by a professional armorer who inspects, test-fires, and cleans each weapon to personally guarantee it meets our quality standards. We love ’em and we think you will too.
