The MATEN will be sold in sets (upper and lower) including a charging handle, threaded bolt catch pin, take down pins, tensioning screw, and door. Individual uppers and lowers are also available, but note that MATEN receivers are only compatible with other MATEN receivers. This was done to guarantee the best possible upper to lower fit, finish, & function. Using the MATEN platform also allows you the most options on your next build.

Bolts & Barrels

Designed to accept any AR style .308 barrels and bolts*. This means you can use your AR10/Noveske or SR25/DPMS components.

*We recommend using the same manufacture for your barrel and bolt. As always assembly should be done by a qualified gunsmith, using the proper head spacing gages.

Hand Guards

Any handguard with a barrel nut designed to fit the Knight SR25 or DPMS will fit the MATEN upper. The MATEN shares a common rail height with the SR25, DPMS High and the Armalite AR10. The necessary cuts have also been included on the upper to use a Samson handguard.


Magazines… take your pick. Any SR25/DPMS compatible magazine such as Magpul, Knight, DPMS, CMMG, and C products.

* MATEN not compatible with Armalite bolt catch.


Do you like to bench shoot? Or maybe your next build is going to be for hunting, or just target shooting. Well you can choose to use whatever trigger best suites your shooting needs. The MATEN lower will accept any AR compatible trigger*.

(*When using an Armalite or Knight carrier a narrower then mil-spec hammer is required. Check with carrier manufacturer.)


By incorporating the Mil-Spec buffer thread on the MATEN lower you have the ability to choose any stock you want. Adjustable Magpul, Mil-Spec A2 and everything in between.
After testing here are some buffer combinations we found work well.

*When using the Vltor AR10 5 position buffer tube an H3 buffer should be used with an Armalite AR10 buffer spring or standard DPMS .308 spring.

*When using a standard 6 position (Mil-spec or commercial buffer tube), use a DPMS .308 carbine buffer & DPMS .308 carbine spring. Or Armalite equivalent.

*When using an A2 stock, the Armalite AR10 buffer and buffer spring, or DPMS .308 standard spring and buffer should be used.
