⚙️ Product Details

Experience precision comfort and rugged reliability with the Luth-AR MBA-5 Adjustable Stock — engineered for shooters who demand balance, control, and customization. Designed to fit Mil-Spec carbine buffer tubes, the MBA-5 combines lightweight polymer engineering with a refined ergonomic design, making it an outstanding choice for AR-15 and AR-10/LR-308 platforms alike.

Constructed from glass-filled nylon polymer, the MBA-5 delivers exceptional strength without unnecessary weight. The integrated paddle-style adjustment lever allows for fast, tool-free length-of-pull adjustments, ensuring the perfect shoulder fit whether you’re in prone position, supported shooting, or rapid-transition CQB scenarios.

A flared cheek rest provides stable alignment for consistent eye relief with optics, improving accuracy shot after shot. The anti-rattle set screw ensures a rock-solid lockup on Mil-Spec buffer tubes — no wobble, no noise — while the rubberized buttpad absorbs recoil for better control and comfort during extended sessions.

For added versatility, the MBA-5 includes a Picatinny rail section along the underside for mounting accessories such as monopods, sling adapters, or rear supports. This feature makes it ideal for benchrest shooters, competition setups, or tactical marksmen who need reliable rear support for precise follow-through.

Whether you’re fine-tuning a precision rifle, upgrading your duty weapon, or building a competition-ready AR platform, the Luth-AR MBA-5 is built to perform in any environment. It’s the perfect balance of lightweight adjustability, durability, and comfort — everything you expect from Luth-AR engineering.
