This is an adapter with a pre-installed buffer tube that allows mounting of any traditional M4 style stock like APS RS3 to the Nano Carbine. It slides into the Core Mount and is fixed in place with a single screw.

The adapter is extremely durable and has an embedded steel nut for maximum strength. The Buffer Tube is an off-the-shelf metal part made by APS. 


To use this part you need to have following items:

Optional parts that are compatible:


This part is fully compatible with SSX23, other MK23 clones and Tokyo Marui MK23.

MK23 Light Trigger Pull Kit by LayLax is not compatible - the hammer is bigger than the original and conflicts with inside surface of this part.


This part is made out of PA12 Nylon using HP Multi Jet Fusion technology which is an industrial grade 3D printing technology, similar to SLS. This makes the parts virtually indestructible with an amazing matte black surface finish. The strength and looks are very similar to injection molded parts.

Sturdy, easy install

Does its job well. I used a stock I had at home so it had a ton of play on the tube. Buy the stock too if you're getting one of these. I do recommend it but you'll need a riser for some optics.

Does what it says on the tin.

Novritch tube stocks (ssx303etc) need some shimming with tape or they are extremely wobbly. Would appreciate if the exact dimensions of the tube were listed so they can be compared with mil std and other producer stocks.

Very sturdy, No complaints. I would recommend this rather than the folding stock if you hare building a sniper carbine.
