Description
The Luth-AR MBA-2 Skullaton takes the tried-and-true A2 rifle stock and strips it down to what matters. It keeps the familiar 13.5-inch length of pull that A2 shooters already know and love, but the fully skeletonized shape drops the weight to right around 11.5 ounces. If you have run a standard A2 stock, you already know how it shoulders. This one feels the same up top but noticeably lighter overall, which adds up over a long day at the range or in the field.
It is molded from super-strong glass-filled nylon, so it holds up to real use without adding bulk. The castle nut and lock ring are built right into the design, which means installation is quick and the finished setup sits tight with no rattle. It ships with the A2 buttstock screw and drops onto a standard rifle-length A2 buffer tube. Note that the buffer tube itself is not included, so if you are starting from scratch you will want to grab a rifle-length tube kit to go with it.
What Sets the MBA-2 Skullaton Apart
Beyond the weight savings, the Skullaton gives you multiple sling attachment points so you can rig it up however your build calls for. It is a simpler, non-adjustable take on Luth-AR's modular lineup, which makes it a great pick for anyone who wants clean lines and dependable performance without extra moving parts. The rubber butt pad keeps it planted in your shoulder for consistent, repeatable shots.
Fit, Compatibility, and Add-Ons for the Skullaton MBA-2
This stock fits all .223 AR-15 rifles and most .308 AR-10 platforms running a rifle-length A2 tube. It is interchangeable with standard A1 and A2 buttstocks, so it is a straightforward swap on an existing rifle. Keep in mind it does not work with carbine or collapsible setups that use six-position telescoping tubes. If you want to fine-tune your fit down the road, Luth-AR offers a cheek riser and butt-plate assemblies that bolt right on to dial in comb height and length of pull.

Frequently Asked Questions
What buffer tube does the MBA-2 Skullaton need?
The MBA-2 mounts to a standard rifle-length A2 buffer tube. The buffer tube is not included with the stock, so if you are building from scratch you will need a rifle-length tube kit. It will not fit carbine or collapsible setups that use six-position telescoping tubes.
Will the Skullaton MBA-2 fit both AR-15 and AR-10 rifles?
Yes. It fits all .223 AR-15 rifles and most .308 AR-10 platforms as long as they run a rifle-length A2 tube. It is also interchangeable with standard A1 and A2 buttstocks, so it is an easy swap on an existing build.
How much lighter is the MBA-2 than a standard A2 stock?
The skeletonized design brings it down to about 11.5 ounces while keeping the same 13.5-inch length of pull as a traditional A2 stock. You get the familiar feel and cheek weld with a real drop in weight, which makes a difference over long sessions.
Can I adjust the fit on the MBA-2 Skullaton?
The MBA-2 itself is a fixed, non-adjustable stock. That said, Luth-AR offers add-on accessories like a cheek riser and butt-plate assemblies that bolt on to raise comb height or extend length of pull if you want to tune the fit.
