Complete upper receiver assembly chambered in the classic 40 S&W pistol round. Includes one 20 round polymer magazine with last round bolt hold open feature. Standard with Picatinny flat-top upper receiver, heavy barrel and picatinny gas block - ready for installation of your optics.
Upper is 100% complete with bolt carrier assembly and charging handle. Ready to drop-on any standard AR15 lower receiver. Simply attach the upper and swap out to the 40 S&W magazine, and you are ready to shoot. Swap back and forth between calibers as fast as you can swap out the upper receiver and magazine.
This caliber conversion does not require the changing of hammers, triggers, buffers or buffer springs. No need to add in a magazine well adapter or mag well plug either. Designed to work with any standard, unmodified AR15 lower with A2 or collapsible stocks.

Don't forget extra magazines, and spare parts!
All Olympic Arms pistol caliber carbines and upper conversions are BLOW-BACK operated, and are NOT a delayed direct gas impingement system.
