Key Features

• Pinned 13.7″ Barrel – The muzzle device is pinned and welded to reach 16″ overall length, making it compliant with NFA regulations while keeping the handling of a shorter barrel. Why it matters: You get the balance of a compact rifle without the tax stamp or wait.
• SOLGW Quality Control – Every SCALPER is assembled by Sons of Liberty Gun Works with their proprietary bolt carrier group and handguard. Why it matters: Consistency and reliability are built in, not hoped for.
• Flat Dark Earth Cerakote Finish – The entire rifle wears a durable, low-glare FDE coating. Why it matters: It resists wear from holsters, slings, and rough handling while blending into most environments.
• 30-Round Magazine Included – Ships with one 30-round magazine for immediate use at the range or in training. Why it matters: You don’t need to buy extra gear to start shooting.
• Chambered in .223 REM / 5.56 NATO – Accepts both calibers, giving you flexibility in ammunition selection. Why it matters: You can shoot cheaper .223 for practice and 5.56 for duty or defense.

Who It’s For

This rifle is built for the traditional shooter who values a no-nonsense, combat-ready AR without paying for extras they don’t need. It suits the quality-conscious buyer who wants a rifle that will hold zero, feed reliably, and last for years of hard use. If you prefer a mid-length gas system and a pinned barrel that avoids NFA hurdles, the SCALPER fits your carry and training routine.

Pros & Cons

• Pros: Reliable function, pinned barrel for legal 16″ overall, FDE Cerakote finish, SOLGW lifetime warranty, includes one 30-round magazine.
• Cons: The pinned muzzle device limits future barrel swaps without a gunsmith; the 13.7″ barrel may not be ideal for long-range precision beyond 400 yards.

FAQ

Is the barrel truly pinned and welded?

Yes. The muzzle device is pinned and welded to the 13.7″ barrel, bringing the overall length to 16″. This makes it compliant with the National Firearms Act as a standard rifle, not a short-barreled rifle.

Can I remove the muzzle device later?

Technically yes, but it requires a gunsmith to drill out the pin and reweld a new device. The barrel is not designed for quick swaps. If you plan to change muzzle devices, consider a 16″ barrel instead.

Does it come with a case?

The SCALPER ships in a cardboard box with foam inserts. It does not include a hard case or soft bag. You may want to purchase a separate storage solution.

What magazines are included?

One 30-round magazine is included. It is a standard AR-15 pattern magazine, compatible with most aftermarket options.
