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.

Manufacturer details
The latest update from HK-USA to the commercial variant of the legendary HK416, the MR556 A4 and MR762 A4 represent an enhanced example of no compromise HK performance. Its short-stroke gas piston operating system does not impart hot carbon fouling back into the action, allowing the weapon to run longer, with less maintenance and with less wear on internal components than direct-impingement ARs. Its adjustable gas regulator allows the operator to tune the action specifically for suppressed or unsuppressed operation. Fully ambidextrous controls, lighter weight and a slimmer profile make the A4 easier to operate, manipulate and employ. For those who demand an AR with unmatched capability and uncompromising reliability and durability, the MR A4s remain the top tier solution.

A note on accuracy. We work hard to keep every listing correct, but specifications, images and compliance details come from many sources and can contain errors or change without notice. 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. All sales are subject to applicable federal, state and local law and to the buyer's eligibility to purchase.
