Is this compatible with a smooth buffer tube
Answer:
Hi Mike! Here is Luth-AR's own answer to your question:
Our stocks are designed to work with Mil-Spec and Commercial buffer tubes. While we cannot guarantee that all manufacturers' buffer tubes meet those specifications, the MBA stocks should work with the buffer tube that came with your gun. If you have an issue with the MBA stocks fitting your existing buffer tubes we offer buffer tubes and complete kits that meet the proper Mil-spec and Commercial specifications.
The MBA-1 and MBA-2 Buttstocks are Rifle Buttstocks and require an A2 style buffer tube. These are fixed buttstocks. You can distinguish the A2 rifle buffer tube from carbine buffer tubes by its shape: the A2 rifle buffer tube is completely round, while carbine buffer tubes have a rectangular appendage enclosing six adjustment position holes. An A2 Rifle buffer tube has no length-of-pull adjustability and is substantially longer than a carbine buffer tube.
The MBA-3, MBA-4 and MBA-5 are Carbine Buttstocks and require the use of a Carbine buffer tube. The MBA-3, MBA-4 and MBA-5 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, MBA-4 and MBA-5).
Carbine buffer tubes typically have 6 positions of adjustability, and can be distinguished from an A2 style Rifle buffer tube, which offers no adjustment positions. Carbine buffer tubes also differ from the A2 by their shape: the A2 Rifle buffer tube is completely round, while carbine buffer tubes have a rectangular appendage enclosing 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, MBA-4 and MBA-5 should fit the buffer tube. Using a Commercial buffer tube with an MBA-3, MBA-4 and MBA-5 will typically provide a more “snug” fit due to the slightly larger diameter of Commercial buffer tubes.
