A Sons of Liberty Gun Works 5.56x45mm NATO bolt assembly gives you OEM-spec reliability for your AR-15 build or replacement. This is the heart of your rifle's ignition system—where precision machining and heat treatment make the difference between a smooth-running platform and headaches downrange. Sons of Liberty manufactures these bolts to military specifications, so you're getting the same standards applied to duty rifles, not a budget compromise.
The bolt is machined from Carpenter Technology No. 158 steel, a premium alloy chosen for its strength and durability under repeated firing cycles. After machining, it's heat-treated to military spec, shot-peened to relieve stress and extend service life, and vibratory tumbled for a clean, uniform finish. That process sounds clinical, but it means a bolt that will cycle reliably, resist premature wear, and handle whatever you feed it—whether you're running suppressed subsonic loads, pushing volume at the range, or depending on your rifle in the field.
If you're building an AR or replacing a worn bolt in an existing rifle, a quality OEM-spec assembly is a no-compromise choice. This isn't a budget part; it's the kind of thing you install once and forget about. Compatible with mil-spec AR-15 platforms, it's straightforward to install for anyone comfortable with basic rifle maintenance.
| Caliber | 5.56x45mm NATO |
| Platform | AR-15 (Mil-Spec) |
| Material | Carpenter Technology No. 158 Steel |
| Finish | Vibratory Tumbled |
| Heat Treatment | Military Specification |
| Manufacturer | Sons of Liberty Gun Works |
This is a mil-spec bolt assembly designed for mil-spec AR-15 platforms. If your rifle is a standard mil-spec AR-15 chambered in 5.56x45mm NATO, it will function correctly. If you have a proprietary or non-standard platform, verify compatibility with your rifle's manual or manufacturer.
This bolt is machined from premium Carpenter Technology No. 158 steel and heat-treated to military specifications. Budget alternatives may use lower-grade materials or inconsistent heat treatment. The shot-peening and military-spec process extend durability and reliability, especially under sustained fire or hard use.
Yes, if your existing bolt is from a mil-spec AR-15, this assembly can replace it. Basic disassembly and reassembly of your bolt carrier group is required—a straightforward task for anyone comfortable with standard AR-15 maintenance.
Shot-peening is a process that bombards the surface with small steel balls, creating a layer of compressive stress. This relieves internal stress from machining, reduces the risk of fatigue cracks, and extends the bolt's service life under repeated firing cycles.
