Buttstocks are responsible for allowing shooters to have better control over their weapons. A good buttstock should be lightweight yet durable, with good recoil absorbency. Also buttstock should, preferably, be adjustable to accommodate all the different shapes and sizes of shooters out there. With all these features in mind, the LUTH-AR MBA 1 Stock has it all.

Lightweight Precision LUTH-AR Stock

The LUTH-AR MBA-1 is one of the most lightweight adjustable buttstocks on the market. At 1.26 pounds, it weighs fully half the weight of competing buttstocks on the market. This glass-filled nylon buttstock is extremely durable with the added benefit of minimal weight.

One of the most important criteria to be considered when purchasing or modifying a rifle is its length of pull. If the weapon does not fit your length of pull, you may be unable to fire the rifle accurately. Thankfully, the LUTH-AR MBA-1 is fully adjustable for both length of pull and cheek weld. This Luth-AR stock is also fully ambidextrous and is suitable for both right-handed and left-handed shooters. Furthermore, the Luth-AR MBA is interchangeable with A1 and A2 buttstocks, as well as any other aftermarket stock with an approximate length of 10.5 inches.

For a lightweight stock that’s quick to install, consider the LUTH-AR Modular Buttstock as the solution to the shooter's dual need for simplicity and strength.

The LUTH-AR Modular Buttstock Assembly (MBA) comes in: Black and Flat Dark Earth.

  • Nice stock

    Nice stock and when adjusted it greatly enhances the alignment of scope for quick target acquisition. LOP adiusts quickly and easily. Cheek riser is nice but not as easily adjusted.

  • Solid Stock

    Solid rifle stock, love the fit, finish and feel on my AR. It’s plenty sturdy, has ample amounts of adjustability and looks great. I’m more into intentional slow long range shots so appreciate the hook for my supporting hand when prone. Gentle reminder to buy a rifle buffer kit as it won’t fit your standard carbine tube.

  • A lightweight tank

    It's everything you need in a modular adjustable butt. I'm in CA and this won't work with compliant grips without modification. I'm going to have to remove the rib between the back of the lower and the point on the stock where it turns down behind the sling attachment point. Still looks bomber and that's no fault of LUTH-AR. I haven't dropped it, don't plan to but construction looks rugged. Buy.
