Additional Information

The MBA-4 does not include the following accessories, they can be purchased on our website separately in the Accessories section:

  • Sling Swivels (Side or Rear) Sold Separately, see below.
  • Carbine Buffer tube
  • Carbine Buffer Body
  • Carbine Spring
  • Latch Plate
  • Lock Ring

Installation Notes:  

  • When tightening the anti-rattle set screw, be careful not to over tighten as the threaded insert may separate from the plastic stock body
  • When sliding the buttstock onto a 6-position buffer tube, the lock pin has a notch in the head of the lock pin that must line up with a tab on the stock body. Once the slot and tab are lined up, the pin can be fully retracted allowing the buttstock to slide onto the tube. The MBA-4 should slide easily without resistance. If there is any resistance, the lock pin is not fully retracted. 

Luth-AR Note on Savage Rifles:

Our MBA-4 is designed to fit standard Mil-Spec and Commercial Tubes. Some Savage tubes have been found to be oversized making our stock fit very tightly. Please note that you may need to simply purchase a standard carbine tube in order for this to pair correctly. Note: Customers have reported that the MBA-3 or MBA-4 fit the buffer tube that comes on the new model 110 BA Stealth. If you have the older model 110 BA you may have to simply change the buffer tube.

Buffer Tube Requirements

The MBA-3 and MBA-4 are Carbine Buttstock and requires the use of a Carbine buffer tube. The MBA-3 and MBA-4 will fit either a Mil-Spec or a Commercial buffer tube. (Note: Some commercial buffer tubes may be oversized from industry norms and may not fit. All commercial buffer tubes sold by Luth-AR will fit the MBA-3 and MBA-4).

Carbine buffer tubes typically have 6 positions of adjustability, and can be distinguished from an A2 style Rifle buffer tube that offers no adjustment positions. Carbine buffer tubes also differ from the A2 by their shape, the A2 Rifle buffer tube is completely round in shape while the carbine buffer tubes have a rectangular appendage to the tube that encloses six position holes. An A2 Rifle buffer tube is substantially longer than a carbine buffer tube.

Carbine buffer tubes typically are offered in two types, Mil-Spec or Commercial. The Mil-Spec carbine buffer tube is visually identified by the 90 degree “cut” at the closed end of the tube. The Commercial carbine buffer tube is visually identified by the 6 degree slant “cut” at the closed end of the tube. A Mil-Spec tube should meet Military Specifications while Commercial tube dimensions are determined by the manufacturer and are typically made from an extrusion. As long as a Commercial buffer tube does not exceed 1.172? in diameter the MBA-3 and MBA-4 should fit the buffer tube. Using a Commercial buffer tube with an MBA-3 and MBA-4 will typically provide a more “snug” fit due to the slightly larger diameter of Commercial buffer tubes.
