What is the LUTH-AR LLC - AR-15 Modular Stock Assy Fixed Rifle Length BLK?

The Luth-AR Modular Buttstock Assembly (MBA) for AR style rifles is designed to replace the standard buttstock on your AR. The MBA-1 is designed to work with a standard A2 rifle style buffer tube and features Length-of-Pull adjustment and an adjustable cheek rise in a low-cost, lightweight, strong and high-quality design. The modular design of the MBA Buttstock allows you to configure your buttstock to your specific and personal needs.

The MBA-1 requires a A2 Rifle buffer tube.

The MBA features multiple attachment points for a sling, including molded pockets that will accept Grovtec QD cups, sold separately (use part# 593-000-038). A rail attachment is available.

First Luth Product, will not be the last
When I first took on this endeavor, I was not sure if this idea would be strong enough for my Noreen 50BMG, after about 50 rounds of Ammo, I am sure it was the right move. No issues at all. Perfect compliment to the firearm, could not have done better with any other solution.
Would you recommend this? Yes, I would recommend to a friend

Great stocks
I have these stocks on 5 of my AR’s. They are super comfortable. It’s nice to have all the adjustment capability’s in this price point. I have the magpul PRS Gen 3 on my Creedmoor and I think the Luth AR are better in a lot of ways, number one being the weight. And of course the half of the price!

MAKING A GREAT RIFLE UPPER.......BETTER
BOUGHT THE LUTH-AR RIFLE STOCK SET, INCLUDING BUFFER TUBE, BUFFER, AND SPRING. GOT AWAY FROM THE CARBINE STOCK SET UP. WISE DECISION. IT WILL TAKE A WHILE TO SEE IF IT ALL STAYS TOGETHER AND WILL PERFORM FOR A LONG LONG TIME. MATCHES STOCK SET UP FOR 3 GUN ARMALITE RIFLE.
