LBE Unlimited AR-15 Mil-Spec Buffer Tube Kit - Black

$54.99

Fully Adjustable AR-15 Buttstock for Mil-Spec or Commercial Buffer Tubes

The MBA-3 Buttstock replaces the standard stock on your AR, with complete adjustment for cheek weld, length of pull, and features a 3-axis buttplate. This stock fits onto carbine buffer tubes, whether using the mil-spec or commercial diameter – meaning it fits on basically any AR rifle with a six position tube. This stock is also rattle free, with adjustable tension on top of getting perfect alignment with your optics.

If you’re starting a new build, be sure to pick up a mil-spec buffer tube kit with everything your recoil system needs!

Features

  • Fully Adjustable Carbine Buttstock assembly to mount to a carbine rifle (6-positions mil-spec or commercial tube) – This is our carbine stock
  • The MBA-3 requires a Carbine buffer tube, either Mil-Spec or Commercial. Please review the information provided in the Requirements tab. This stock works with both carbine Commercial and Mil-Spec tubes/assemblies.
  • Additional 1″ height on cheek rest
  • 3-axis Adjustable Butt Plate Assembly extends additional 1 1/16″ length of pull and includes the following movement:
    1. Horizontal for linear adjustment (i.e. length of pull)
    2. Vertical for a perfect butt plate fit into the curvature of the shoulder.
    3. Lateral adjustment for a ½ inch left or right cast
    4. This butt plate assembly is interchangeable with the original MBA-1 Buttstock
  • Includes a Picatinny Rail on the bottom rear of the Stock Body to attach your choice of many accessories.
  • Designed a flat bottom index set screw (10-24) to eliminate that constant rattle of carbine collapsible buttstock. This also allows you to secure the stock in your favorite position.
  • The MBA-3 comes with a  medium soft rubber recoil pad, Duro 85.
  • The Luth-AR MBA-3 weighs roughly half that of comparable stocks coming in at just 18.5 ounces.
  • Fits all .223 and .308 AR carbine style rifles
  • Super Strong Glass Filled Nylon
  • Easy to replace and quick to install
  • Uses 4 out of the 6 positions on a mil-spec or commercial tube

Awesome Stock!

I bought this for an AR platform long ranger 6.5 Grendel rifle I am building. The stock is absolutely amazing! The adjustability is on point and it can fit anyone with the wide range of adjustability. AT3 as always had it shipped out super fast and the price was the best i found.
