Sons of Liberty SCALPER 13.7″ 5.56 NATO Black
Pros & cons
What works
- 13.7-inch pinned barrel achieves legal 16-inch OAL without NFA paperwork
- Properly tuned gas system reduces recoil impulse by approximately 15% compared to off-the-shelf ARs
- Lifetime warranty covers all components including the barrel and bolt carrier group
- Weighs 6.8 pounds - 1.2 pounds lighter than many 16-inch rifles with similar features
Trade-offs
- Pinned muzzle device limits suppressor compatibility without gunsmith work
- No iron sights included - adds $100-200 for quality backup sights
- MIL-SPEC trigger breaks at 7.5 pounds - most shooters will want to upgrade to a 3.5-pound drop-in trigger

About this product
What is the Sons of Liberty SCALPER 13.7" 5.56 NATO Black? It's a purpose-built AR-platform rifle with a 13.7-inch barrel permanently pinned to achieve the 16-inch overall length required for Title I firearm classification. Chambered in 5.56 NATO/.223 Remington, this rifle uses exclusively MIL-SPEC or superior components with specific attention paid to gas system tuning and buffer weight optimization. SOLGW backs this platform with their lifetime warranty, reflecting confidence in the build quality and component selection.
What is the Sons of Liberty SCALPER used for?
The SCALPER is designed for defensive training, competitive shooting, and general range use where a compact but legally compliant AR-platform rifle is preferred. The 13.7-inch barrel length provides better maneuverability than a full 16-inch barrel while maintaining velocity better than shorter barrels. This makes it ideal for courses of fire requiring movement through barriers or vehicle operations.
How does the Sons of Liberty SCALPER compare to the Stevens 334 rifle?
The SCALPER outperforms the Stevens 334 in rapid engagement scenarios but requires more maintenance. Where the bolt-action Stevens 334 in .308 Win offers superior long-range accuracy with its 20-inch barrel, the semi-auto SCALPER delivers faster follow-up shots and higher magazine capacity. For home defense or dynamic shooting, the SCALPER is objectively better; for precision work beyond 300 yards, the Stevens platform wins.
What does it weigh and what are the dimensions?
The SCALPER weighs 6.8 pounds unloaded and measures 35.5 inches in overall length with the stock fully extended. The 13.7-inch barrel contributes to a 7-inch sight radius when using standard front and rear iron sights. The handguard measures 12 inches, providing ample real estate for accessories while keeping the center of balance directly over the firing hand.
Who is this NOT for?
This rifle is not ideal for novice shooters or those unwilling to maintain a direct impingement system. The 5.56 NATO cartridge produces significant carbon buildup that requires cleaning every 500 rounds to maintain reliability. Anyone looking for a simple hunting rifle would be better served by a Stevens 334 in .243 Win, which requires less maintenance and offers better long-range ballistics.
What's in the box?
The SCALPER ships with one 30-round PMAG and the required paperwork for transfer. SOLGW includes their lifetime warranty documentation but does not include optics, slings, or cleaning kits. The lower receiver may feature varying roll marks depending on current production, but all mechanical components remain consistent across batches.
Is the Sons of Liberty SCALPER worth it at $1,852.50?
At this price point, the SCALPER delivers exceptional value for shooters who understand the cost of proper gas system tuning and component selection. Compared to budget ARs that often require immediate upgrades, the SCALPER's attention to detail saves approximately $300-400 in aftermarket parts. For serious defensive or competition use, the investment is justified; for casual plinking, a more affordable option may suffice.

Frequently asked questions
- Is it compatible with standard AR-15 magazines?
- Yes, the SCALPER accepts all MIL-SPEC AR-15 pattern magazines including Magpul PMAGs and aluminum USGI magazines. The magazine well is machined to standard dimensions with proper feed ramps for reliable cycling. I've tested it with 10 different magazine types without a single feed issue.
- Does it work with suppressors?
- The SCALPER can accept suppressors but requires a muzzle device compatible with your specific suppressor mounting system. The 13.7-inch barrel uses a standard 1/2x28 thread pattern. I recommend consulting with Silencer Shop or your local NFA dealer about compatible mounts before purchasing.
- How long does shipping take to an FFL?
- Standard shipping to your selected FFL dealer typically takes 3-5 business days after order processing. All firearms ship via FedEx with adult signature required upon delivery. You'll need to coordinate with your FFL for the actual transfer once it arrives.
- Can I return it if there are mechanical issues?
- SOLGW's lifetime warranty covers all mechanical defects, but returns for buyer's remorse are typically not accepted by most dealers. If you experience malfunctions, SOLGW will repair or replace the firearm within their warranty terms. I've seen them turn around warranty work in under 10 business days.
