THE CORE OF NANO CARBINE

🚚 Estimated Restock for SSX23 Version: January, 2026

This part is the core of any Nano Carbine build. It mounts on the slide using 4 screws and enables you to attach the folding stock or M4 buffer tube.

It also has mounting holes for the Short Picatinny Rail and Long Picatinny Rail, depending on what you want to build with it. It is also perfectly usable without any rails as it leaves the fiber optic iron sights exposed.

It's extremely low profile and fuses with the pistol slide seamlessly.

Compatibility

SSX23 Metal Slide version is only compatible with the Novritsch SSX23 metal slide. It uses the red dot mounting holes to fix in place and requires no modifications whatsoever.

MK23 Plastic Slide version is compatible with all plastic slides including Tokyo Marui / ASG / STTi brand MK23's. Since none of those slides have mounting holes, you will need to drill 4x 2.5mm holes using the included drill jig. Holes can be later closed with M3 grub screws (not included) when you remove the kit from the pistol.
Both Core Mount variants are not compatible with Ascend Ninja 23

We strongly recommend to get the Novritsch SSX23 metal slide as it's compatible with all brand MK23's and will significantly increase the rigidity of the pistol.

Materials

This part is made out of solid piece of CNC machined 6061 aluminum. It has anodized matte black surface and has a small laser engraving on the side.

Customers praised this airsoft mount for transforming MK23 pistols into "pocket snipers" with excellent precision. Shoppers highlighted "top-notch machining," perfect fit with no wobble, and good material quality. Field-tested and highly recommended. One customer noted slide removal requires stock removal first without TDC mod.

Game Changer!

A fully upgraded mk23 was the one of the best thing in airsoft, but really hard to do a clean shot for long distance.

Now with the full tridos nano kit that became a pocket sniper.

Well spendt money!

Good material

MK23 Plastic Slide (TM / ASG / STTi)

Fits perfectly

Fits perfectly on my TM MK23. No wobble.

SSX23 Metal Slide

A really very good product

Just perfect. Validated ön the field 😁 Highly recommended.

SSX23 Metal Slide

My asg mk23

Yeah works quite well. Enjoy using the kit

Well made!

This is the most important piece to turn a SSX23 into a compact carbine. The machining and precision are top-notch!

Does what it says on the tin.

Fits perfectly. Works as intended. Gotta have t to add the other things. If you have somewhat nimble fingers. No problem assembling. I have two full builds.

Fit perfect TM MK23

The TM version fit perfect and has no wobble. On the other hand the problem is if you don't have TDC mod like me. You can not remove the slide together with stock, first you must remove the stock and next the slide to adjust hop up dial. I will buy TDC and your mini TDC Thumbscrew.
