Modularity and versatility are key functions of the AR-15 and AR-10 platforms and are really what set them apart from other weapon systems on the market. Luth-AR took the idea of a simple stock and made it just as customizable as the rifle itself. The Modular Buttstock Assembly is designed to fit on Mil-Spec A1 and A2 rifle length buffer tubes and includes an integrated castle nut and lock ring for an extremely durable and secure set up. The glass filled reinforced nylon design is fully adjustable for length of pull, cheek riser height, and is fully ambidextrous to fit any shooters needs. This fixed stock is a perfect addition to your competition rifle, hunting or varmint rifle, or DMR setup whether it shoots 223 and 5.56 or 308 and 7.62 ammunition.

Note: This model is not compatible with collapsible carbine length 6 position buffer tubes. See product code MBA-3 and MBA-4 for collapsible versions.

The Luth-AR Modular Buttstock Assembly was designed to give competition shooters the edge when on the firing line. Whether the match requires precision long-range shooting or fast cqb shots, this stock can do it all. The rubber recoil pad can be adjusted to a total of 1 1/16” of additional length and the cheek riser can add an additional 1”. The cheek rest can also be switched to the right side for left-handed shooters and moved back and forth depending on your scope eye relief. The adjustments can easily be made with the finger adjustable large knurled knobs on the right side. The stock also includes quick detach sling mounts on either side and features a support hand rest for added stability when taking long distance shots.

The Luth-AR company was founded by the same man who founded the DPMS and Panther Arms firearms companies. Randy Luth started as a machinist and built his way up to leading some of the most recognizable and respected companies in the firearms industry. The Luth company now owns seven patents for high quality AR-15/.308 components and accessories that are built for the competition shooter, hunter, and gun enthusiast.
