MDT SKELETON CARBINE STOCK

Modular Driven Technologies aka “MDT” is well know for being a leader on bolt action rifle chassis particularly their TAC21. MDT is also the rifle chassis provider for Brownells, Winchester, Weatherby and Mossberg to name a few. Many shooters may not realize that MDT also offers a skeletonized carbine stock that with proper buffer system hardware can also be used with the AR-15, AR-10 and 308 AR rifles (See the chart below). The MDT “SCS” is a great Magpul PRS alternative. Available in black or FDE.

MDT SKELETON CARBINE STOCK With CHEEK RISER

For about thirty dollars more than the standard MDT Skeleton Stock there is an upgraded version of the carbine stock the includes and adjustable cheek riser.

MDT SKELETON CARBINE STOCK

The MDT SKELETON CARBINE STOCK has been designed to allow maximum adjustability while minimizing weight. The adjustability allows each shooter to optimize superior ergonomics for multiple shooting positions. The weight has been minimized by skeletonization while retaining the strength of the stock. The SKELETON CARBINE STOCK is crafted in 6061 aluminum with Cerakote®.

The SCS without the cheekpiece weighs 1.43-1.48lbs depending on the length of the buffer tube used and without spacers.

The SCS has 3 QD attachment points (one on each side and one on the bottom) to allow the shooter multiple choices for carrying. The SCS also has provision on the bottom of the stock to allow for the attachment of a picatinny rail.

The user is able to finely adjust the LOP by using the wheel mechanism located on the body of the SCS. LOP can be locked into position by tightening the lower bolt. The angle of the SCS can also be adjusted by loosening the top two screws on the body. This allows the body to align with the buffer tube by using the scribe mark down the buffer tube and the offset scribe mark on the SCS body.

A soft foam guard has been placed on the SCS to allow for use with low optics. This foam guard provides comfort against the elements. The foam guards position is able to be adjusted by moving it horizontally along the buffer tube.

The buttpad on the SCS can be adjusted horizontally, vertically, and angularly. By loosening the setscrew on the rear portion of the buttpad, the buttpad can be adjusted vertically. Once the buttpad has been moved up, two screws will be revealed. To adjust the angle of the buttpad, or move it in the horizontal plane, these screws must be loosened.

The SCS must be used with a custom MDT buffer tube and standard castle nut. This MDT buffer tube has a scribe mark down the center to allow the shooter to zero the angle of the SCS if they wish. On the body of the SCS there is another machined marking to further allow the shooter to precisely angle their stock to suit their needs.

MDT Skeleton Carbine Stock Length of Pull Graph

MDT offers various buffer tubes lengths to allow shooters to choose their Length of Pull. To use these buffer tubes with AR-15 and AR-10 buffer systems, one or more spacers will be included with your purchase.

  1. When using the 8.75” long SCS, an AR15 carbine buffer tube system can be used as it has the internal length of an AR-15 carbine buffer tube. AR-10 carbine buffer tube systems and AR-10/AR15 rifle buffer tube systems are not compatible.
  2. When using the 9.75” or 10.75” long SCS, an AR-10 Carbine Buffer Tube System can be used, as it has the same internal length as an AR-10 Carbine Buffer Tube. An AR-15 carbine buffer tube system can be used with the use of a .625” spacer inserted into the buffer tube.
  3. When using the 11.75” long SCS, an AR-15/AR-10 Rifle Buffer Tube System can be used, as it has the same internal length as an AR15/AR10 Rifle Buffer Tube. An AR-15 carbine buffer tube system can be used with the 2.3” spacer. An AR10 Carbine Buffer Tube System can be used with the 1.7” spacer inserted into the buffer tube.

The buffer tube comes in various lengths to allow for proper Length Of Pull (LOP) for any rifle, while maintaining the correct internal length for an AR-15 buffer system.

MBA MODULAR BUTTSTOCK ASSEMBLY Luth-AR

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.

The below originally at shooting illustrated.

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.

  • Fully adjustable: extra 1″ height on cheek rest, additional 1 1/16″ length of pull with extended length buttplate
  • Approximately half the weight of competitors’ adjustable stocks The “MBA” weighs just 1.26 lbs.
  • Easy to replace and quick to install
  • Fits all .223 and most .308 AR style rifles
  • Super Strong Glass Filled Nylon
