Questions & Answers
I have Luth MBA-1 on my 308 rifle right now. Do I have to change the buffer tube if I will change the buttstock of my rifle to MBA-5? Thanks Manufacturer Answer

The MBA-5 stock does go onto a "carbine" style buffer tube so you would need to change from the tube, spring and buffer the MBA-1 uses.

Will this fit on a Aero Precision M5 .308 rifle buffer tube? Expert Answer

The Luth-AR MBA-5 Stock Assembly will fit to your .308 buffer tube as they are the same as standard AR15 carbine buffers. This buttstock will also fit on commercial and mil-spec buffer tubes with a set of ant-rattle screws designed to tighten up the buttstock when using a mil-spec buffer tube.

Cheap build and quality by Soloshot, Verified Owner, July 21, 2022
Not recommended at all. I unpackaged the product and had it in my hands for about 5 seconds and was like absolutely not. Flimsy and not a good build. Stick with Magpul, BCM, Daniel Defense. Not worth the reduction in ounces. If this stock strikes som...

Great Ergonomics by PRSNewbie, Verified Owner, September 1, 2026
I have been researching for a great bag riding AR15 butt stock and I found this and the ergonomics for me well the recoil pad works well also coming from a Magpul with extended recoil pad even with the open design.

Half finished by JL, Verified Owner, September 10, 2022
First off, I have been a fan of Luth for years. This stock started out as a good idea but they forgot to finish it…or it was finished as an after thought. I still can’t figure it out. Super sloppy on the buffer tube. Their is a “clamp screw” on mine ...
