Simply put the MBA MODULAR BUTTSTOCK ASSEMBLY from Luth-AR is a skeletonized lighter weight alternative the the Magpul PRS. The specs around the internet are confusing. The MBA MODULAR BUTTSTOCK ASSEMBLY from Luth-AR weighs in at 1.25 pounds while the Magpul PRS comes in at 1.68 pounds. It will be interesting to see how Magpul responds to the Luth-AR line of stocks.

MBA MODULAR BUTTSTOCK ASSEMBLY Luth-AR – When it comes to custom stocks for the AR15, 308AR, AR-10 options are pretty much wide open. You can add on a collapsible stock that will allow you to fit the rifle to shooters of different sizes (or different clothing configurations based on location and temperature), there are options for fixed stocks, and there are even stocks that are adjustable for precision shooting. There are even devices that allow you to fold the stock on your gas-impingement-driven AR15.
In this last group, options are less-plentiful than in the collapsible arena. A handful of manufacturers make fully-adjustable buttstocks for the AR15, 308AR, AR-10, so when there was a new player in town, it piqued our interest here at HQ. Luth-AR is a new company started by the founder of DPMS Arms, and the Modular Buttstock Assembly (MBA) is one of its first products.
The unit is solid, with adjustments made without tools using a simple thumbscrew and captured-nut. The stock can be set up for shooters of either hand, with the default set for right-handed shooters. It installs like any fixed stock and cannot be used on collapsible stock assemblies.
Two features set the MBA apart from competitors. The first is the weight—the MBA tips the scales at a featherweight 1.26 pounds. Shooters looking to save some weight on their precision rifle might be interested in the MBA. The second, more surprising feature is the MSRP of $139.95 available directly from Luth-AR and Brownells.
Glass-filled nylon rifle stocks fit onto standard A1/A2 buffer tubes and add adjustments and extra features to AR-15 rifles, including most .308 models. Stocks feature textured rubber recoil pads and 2 QD sling sockets for fast sling mounting and dismounting. Modular Stock gives an adjustable cheek rest, and adjustable length of pull. Weighs less compared to other adjustable stocks. Skeleton Stock has futuristic appearance, and helps reduce weight. Will not fit on carbine buffer tubes. Includes Allen wrench for mounting. Uncle Mike’s QD Sockets (593-000-038) can be epoxied into socket on the side of each stock.
