Armalite is known for its history of innovation. Its Special Purpose Rifle (SPR) has proved it for years. Now, the introduction of the Armalite SPR Mod 1 proves it once more, in spectacular fashion. The SPR Mod 1 is forged, one-piece upper receiver/rail system with exclusive detachable side and bottom rails. Each SPR Mod1 comes with three extra rails standard, at no extra cost. Its one-piece construction offers you a continuous optic platform (COP). There is no gap to bridge between receiver and upper rail when you're installing your scope or sights. This one-piece construction also gives the sighting platform extra rigidity. It's a good strong backbone. That means your sight will stay zeroed in the most trying conditions. Also featuring chrome lined, chrome moly vanadium steel barrel, two stage tactical trigger, steel bolt assembly, hard coated finish, and these are all standard not an add on price.
