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. 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
When it comes to dimensions and the caliber, this is what comes to most people's minds when you say AR15. This CMMG RESOLUTE comes chambered in 5.56x45mm, one of the most prolific calibers in the world, and for good reason. 5.56, and its counterpart .223 Rem, have seen service with militaries, hunters, and recreational shooters for decades. Whether you're considering your first rifle or picking a new addition, a 5.56 RESOLUTE carbine is a staple for any collection. If you're after a particular look or have a certain AR accessory that fits you best then don't worry, this 5.56 RESOLUTE is built on their Mk4 platform and accepts virtually any and all AR15 accessories. When full-size rifles are too cumbersome and pistols/SBRs don't deliver the long-range ballistic performance you need, the CMMG RESOLUTE line of carbine length rifles is the answer. Fitted with the suite of ZEROED parts and accessories as well as their legendary RIPSTOCK, the RESOLUTE is the rifle that's never out of place. The new EML 15 handguard brings style to the next level. M-LOK attachment slots are found where expected at the 3, 6, and 9 o'clock positions as well as on top at 12 o'clock with the omission of a full-length Picatinny section found on their previous handguard. This reduces weight while the additional M-LOK section still gives shooters a place to mount those must have accessories.
