CA Compliance:
California compliance
- Status: Legal to own in California.
- Configuration: Fixed magazine (CompMag), installed by WBT. The CompMag is a fixed 10-round magazine that stays in the rifle and loads one round at a time from the side through a loading port, so the rifle keeps its pistol grip, stock and muzzle device and is never opened to reload. It fits most rifles that take a standard AR-15, AR-10 or AK-47 magazine.
- Magazine: 10-round CompMag, fixed in place; loads from the side.
- 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
LMT Defense MARS-H DMR is a large-frame AR chambered in .308/7.62x51 with a 20" barrel and an 8-round capacity. Finish: Black. WBT configures it for California at our Yuma, Arizona warehouse before it ships.
Manufacturer details
Utilizing the LMT patented Monolithic Rail Platform, MRP. The only true monolithic rail platform, milled from a single solid piece of aerospace aluminum forging. It utilizes two locking bolts accessible from the side of the receiver to lock in the barrel extension. This patented technology engages the barrel extension for a full 360 degrees around the extension and makes the barrel removable within seconds with a return to zero of the same barrel. One receiver can utilize numerous barrels of varying length, material, and caliber.
The upper receiver has 19.25″ of picatinny rail on the 12 o’clock position. The remaining 7 sides provide M-LOK compatible attachment points.
MARS-H barrels utilize a low profile gas block and straight gas tube. They possess proprietary coating and are cryogenically treated for long term durability.
The MARS-H ambidextrous lower receiver features our EDM machined two-stage trigger, winter trigger guard, endplate with QD swivel point, LMT ergonomic textured grip, and SOPMOD stock. The ambidextrous features include bolt catch and release, magazine catch, and safety selector. As with all LMT lower receivers, the extension tube is coated with dry film lubricant.
