CA Compliance:
California compliance
- Status: Legal to own in California.
- Configuration: Featureless, built by WBT: grip fin in place of the pistol grip, stock pinned in a fixed position, flash hider removed and replaced with a thread protector (a muzzle brake is an optional upgrade). The magazine release works normally, so reloads are the same as anywhere else.
- Magazine: Standard detachable, 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.
- Upgrades: Prefer a more comfortable featureless grip (Sparrow Dynamics, Juggernaut Tactical, Strike MegaFin)? See California Compliance Upgrades. Want a muzzle brake in place of the thread protector? Add either to this order and they ship installed.

About this rifle
HK MR762A1 Long Rifle Package III is a large-frame AR chambered in .308/7.62x51 with a 16.5" barrel and a 10-round capacity. Finish: Flat Dark Earth, Black. WBT configures it for California at our Yuma, Arizona warehouse before it ships.
Manufacturer details
Taking an essentially standard MR762A1 (caliber 7.62 x 51 mm NATO) semi-automatic rifle, Heckler & Koch USA turns it into a more effective precision rifle by an astute addition of the right optics and accessories. A Vortex Viper PSTII 3-15×44 FFP MRAD, HK G28 adjustable cheekpiece buttstock, and LaRue Tactical BRM-S bipod are the primary add-ons that make the MR762A1 Long Rifle Package (LRP) more than a sum of parts.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.”
