CA Compliance:
California compliance
- Status: Legal to own in California.
- Configuration: Fixed magazine (Juggernaut Tactical Hellfighter kit), installed by WBT. The kit replaces the bolt catch with a mechanism that locks the magazine in place and includes quick-release takedown hardware. The rifle keeps its pistol grip, adjustable stock and flash hider; to reload, you open the action, swap the 10-round magazine and close it.
- Magazine: 10-round.
- Your options: If this page shows a compliance selector, choose the build you prefer and we configure it that way. If not, this is the configuration we offer by default; on AR-pattern rifles and some AKs a different build is often possible, so ask us before you order.

About this rifle
Heckler & Koch MR762 (Factory Compliant) is a large-frame AR chambered in .308/7.62x51 with a 16.5" barrel and a 10-round capacity. Finish: Black. WBT configures it for California at our Yuma, Arizona warehouse before it ships.
Manufacturer details
Like its 5.56 mm counterpart, the MR762A1 is a direct descendent of the HK416/417 series, only in a semi-automatic rifle configuration developed for civilian users. It is assembled in the USA using US and German-made components and uses many of the same parts and assemblies developed for the legendary HK416 and 417.
The MR762A1 uses a proprietary HK short-stroke gas piston in place of the direct-gas-impingement system found on lesser AR15-style rifles that propels exhaust gas into the upper receiver to operate the action. In the “closed” HK piston system, exhaust gasses never enter the receiver, which means the HK runs cooler, cleaner and more reliably. And when adverse conditions, like dust, sand and mud are introduced, the advantage of the HK system becomes even more drastic. That is why so many of the world’s elite military and law-enforcement customers have absolute trust in their HKs.
The MR762A1 has a cold hammer forged barrel made from the highest quality cannon-grade steel, producing a barrel that ensures superior accuracy, even after firing thousands of rounds. And while the material and cold hammer forging process themselves greatly enhance durability, HK’s processes include many additional steps not taken by other manufacturers to produce superior accuracy and service life, ensuring performance well beyond “mil-spec.”

Images may show a configuration that is not California-legal. If a detail on this page matters to your decision, call us and we will confirm it against the actual firearm before you order. The compliance information here is general in nature and is not legal advice; California and local laws change, and the configuration described is confirmed at the time of sale.
