Mega MATEN .308 Precision Rifle | 24” Lilja | Nightforce ATACR | Geissele | LaRue | Loaded Package

If you know what you’re looking at, this is not a typical AR-10. This is a serious precision .308 gas gun built on a Mega Arms MATEN billet receiver, one of the most respected large-frame platforms from the era before Mega was acquired by ZEV Technologies. Original Mega-marked MATEN builds like this have become harder to find, especially when they’re done right and not pieced together with filler parts.

At the core of this rifle is a 24” Lilja Precision stainless barrel chambered in .308 Win with a 1:11 twist, a combination known for consistency and real long-range performance. It is paired with a Geissele trigger system that delivers the clean, predictable break you expect in a true precision setup. The rifle is configured for stability and control with a Magpul PRS precision stock, a free float handguard, and a large multi-port muzzle brake that keeps recoil flat and manageable under sustained fire. An ergonomic rubberized grip rounds out the handling without overcomplicating the build.

The glass alone puts this rifle in a different category. Sitting on top is a Nightforce ATACR 5-25x56 F1 with 0.1 MRAD adjustments, mounted in a LaRue Tactical QD mount, and it is complemented by a LaRue bipod. This is not entry-level glass or budget mounting hardware. This is a complete, ready-to-run precision package built with components that experienced shooters recognize immediately.

Everything about this rifle reflects a time when builds were driven by performance, not trends. Mega MATEN receiver, Lilja barrel, Geissele trigger, Nightforce ATACR, LaRue mounting system and bipod. There are no weak links in this setup. You could easily spend the time and money trying to recreate something like this today and still not match how well this one is put together. Condition is excellent with light handling wear consistent with careful ownership. It is clean, well-maintained, and presents exactly like a rifle that was built with intent and taken care of accordingly. This is not a worn-out range gun or a slapped-together build.

High-end MATEN builds with Lilja barrels and ATACR optics do not come up often in this condition. If you’ve been looking for a properly built .308 precision gas gun without cutting corners, this is one to act on. All used firearms are sold as is, with no warranties expressed or implied.
