ArmaLite’s “History of Innovation” continues! The originator of the AR platform has turned its popular M-15 SPR Mod 1 system into a “Family of Calibers.”

ArmaLite’s Mod 1 carbine started as a .223/5.56mm carbine built around a revolutionary one-piece upper receiver/rail system with exclusive detachable side and bottom rails.

This year, ArmaLite goes a step further, introducing the SPR Mod 1 6.8mm SPC II and the SPR Mod 1 7.62X39mm. Both mid-length carbines continue the “ArmaLite Standard of Excellence.”

ArmaLite’s SPR Mod 1 6.8 is especially well-suited to hunting. It is powerful enough to meet the minimum energy requirements of many states for taking medium sized game such as deer. At the same time, the 6.8mm is lighter than the 7.62×51, reducing the weight of ammunition carried into the field. As part of the AR-platform family, this carbine is also more versatile and ergonomic than traditional hunting models. The Mod 1 6.8mm is built with the ArmaLite-developed mid-length handguard and gas system to provide the best in form and function.

ArmaLite’s SPR Mod 1 7.62X39mm provides all the flexibility of the Mod 1’s one piece upper receiver/rail system but now for the world’s most available cartridge. The original AK-47 was built to use this cartridge.
Now, enthusiasts of the 7.62X39 won’t have to settle for less than the best: a true ArmaLite carbine. The ArmaLite designed mid-length handguard and gas tube technology provides an optimal gas pulse to power the 16″ system so reliability is never an issue.

More on the SPR Mod 1 platform:

The SPR Mod 1 is forged, one-piece upper receiver/rail system with exclusive detachable side and bottom rails.

In true ArmaLite fashion, the SPR Mod 1 is like no other on the market. With other one-piece systems, you’re stuck forever with the rails you get at purchase, and stuck with their limits.

But ArmaLite knows you and your firearm often have more than one mission, and you want options. ArmaLite gives you just that. The SPR Mod 1’s three o’clock, six o’clock, and nine o’clock rails are detachable. That’s right, you can change your 1913 rails to fit your changing needs for sights… lights…lasers…grips…or swivels.

ArmaLite takes that versatility even further. Each SPR Mod 1 comes with extra rails standard, at no extra cost. We give you a 1913 rail with quick detachable sling swivel hole. Each rifle comes with a low insert for when you need a bare rail with a low profile. There’s also a plain insert with a quick detach sling swivel hole. And there is a half plain, half Picatinny rail as well. Changing your rails…your add-ons…and your SPR Mod 1… is as easy as turning a torx wrench.

Ingenious versatility isn’t the only reason you’ll want an SPR Mod 1. Its one-piece construction offers you a continuous optic platform (COP). There’s 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 sights will stay zeroed in the most trying conditions.

The SPR Mod 1 typifies the “ArmaLite Standard of Excellence.” With us, quality comes standard. There’s no extra charge for: the SPR Mod 1’s chrome lined, chrome moly vanadium steel barrel; its two-stage tactical trigger; the patented, extra strength steel bolt assembly; or the hard coated finish. These are all things that the other companies consider options at an added cost.
The introduction of the new ArmaLite SPR Mod 1 is truly a new chapter in our history of innovation and our dedication to the quality you deserve.
