The OA-15 M4 comes with collapsible stock (6-position M4), M4- handguards and A2-grip. Button-rifled, stress relieved Lothar Walther stainless steel heavy match barrel, 0.750 diam. The barrel is already black coated. Ambi-Selector, the big charging handle, 14/1-thread and flashhider are included as well as the detachable A3 carrying handle. Upper and Lower Receivers are machined from solid billet. The Aluminium alloy is two times stronger than stainless steel, the range of its applications are aerospace parts as well as rims for racing cars. We brought down the tolerances to a minimum which guarantees a perfect, tight fit between Upper and Lower Receiver. The parts are fine-blasted before they receive their hardanodizing. The Rail of the Upper is a MilSpec Picatinny (MilStd 1913) which ensures a tight fit of high-quality mounts like A.R.M.S. Lothar Walther stainless Steel Match Grade barrels are used. |
