Looking for a replacement for your old and worn out A1/A2 rifle stock but don’t want something heavy and over complicated? The Luth-AR Skullaton buttstock assembly is the right choice for you as it takes the same design principle as the tried and true M16 rifle stock and improves upon it in only the necessary ways. It has a skeletonized structure made from glass filled reinforced nylon to reduce weight while still being extremely strong and attaches to the same A2 standard buffer tube. Another improvement that the MBA-2 has over the Mil-Spec fixed stock is the adjustable cheek riser, QD sling attachment points, and integrated castle nut with lock ring to ensure a rock-solid setup with no rattle. Install this new and improved buttstock to your 3 gun competition AR-15 or AR-10 and experience the simplicity and durability of fixed rifle stocks with ergonomics from the 21st century.

  • Light weight and durable glass reinforced nylon
  • Skeletonized structure
  • Fits all .223 and .308 AR style rifles with rifle length buffer tube
  • Comes with A2 buttstock screw
  • Integrated castle nut and lock ring
  • Compatible with Luth AR cheek riser
  • Compatible with Luth AR butt plate assembly
  • Reversible QD sling slot (GT-CUP required)

The Luth-AR Skullaton rifle stock is built with competition in mind where simplicity and durability are key for consistent cheek welds and accurate shots. It only weighs 11.01 ounces, so you can use it all day and features a rubber butt pad to provide leverage and keep it locked into your shoulder. The butt pad can also be replaced with the Luth-AR butt plate assembly to further customize length of pull and angle. Additionally, you can add a cheek riser to get a consistent sight picture down your variable optic for those long-range shots.

The Luth-AR company was founded by the same man who founded the DPMS and Panther Arms firearms companies. Randy Luth started as a machinist and built his way up to leading some of the most recognizable and respected companies in the firearms industry. The Luth company now owns seven patents for high quality AR-15/.308 components and accessories that are built for the competition shooter, hunter, and gun enthusiast.

Not quite what I expected


I expected a 40$ stock to be cheap and flimsy, not at all the case. Awesome quality and easily installed!

Fit was excellent.


I think I am going to really like this unit. I just installed it but it looks and fits great. Certainly is a change from the stock collapsible stocks and the standard A2 stock.

Great stock


Love this stock.

luth stock


Stock is very stable , snug fit and looks just right on my yugo m77

Great stock, quick warning for those converting from a collapsible stock AR


Great stock overall and I look forward to installing and using it, but a word of quick warning for AR's, if you are replacing a collapsible stock with this fixed stock, it is almost guaranteed that you will need to buy and replace your comm or mil spec buffer tube with a completely round "receiver extension tube" version. This is only barely hinted at in the product description with the mention of it being an A2 conversion. I'm having to convert my collapsible stock AR to a fixed stock as a way to legally comply with some of CA's new gun laws (featureless rifle) and up till this point, a fixed stock or potential for a different buffer tube was never even on my radar of things to research. And most local gun stores do not carry these in stock since very few AR owners use fixed stocks. But like I said, the stock itself is great, well made, sturdy, and I look forward to installing it.

Not Thrilled

The thing that looks like a butt pad is hard plastic, has no give just a little rubber strip on it. The hole on the side is not a quick detach point, it is a hole that could hold a quick detach point if you order one separately. Honestly I am completely disappointed in this stock and there are many better options for the same price or less.

Great Stock

Love this stock. Solid, and very lightweight. Use it on my back packing rifle. Nice hook for your support hand.
