- DMR MK23 Carbine platform
- 6.03mm Tightbore inner barrel
- 0.8-0.95 Joule & 1.7-2.5 joule versions
If you are a sniper who is fed up with the wind ruining their kills or you have a sneaky playstyle and want to push your effective range up into DMR territory, the Novritsch SSX303 is calling your name!
This MK23-based DMR carbine is built like a tank and shoots like a laser beam thanks to its high FPS setup with an extended 6.03mm tightbore inner barrel, TDC HOP-up unit with a tool-less external adjuster and highly efficient non-blowback action.
The chassis of the SSX303 is constructed from CNC-machined aluminium, and as we would expect for a modern platform, is bristling with M-LOK negative space attachment slots with a 36cm long 20mm Picatinny top rail, ready for your choice of optical sight.
The controls of the SSX303 are all ambidextrous, making it a fantastic alternative to a bolt-action sniper rifle for left-handed shooters, and the stock mounts to a standard M4/AR-15 buffer tube, opening up about a million options when it comes to mounting aftermarket stocks.
Whether you are a stealthy woodland warrior or you fancy giving the DMR playstyle a go, you'll have a hard time finding anything with a better blend of low weight, long range and near-silent muzzle report than the SSX303 Stealth DMR Gas Non-Blowback Rifle!
- CO2 Magazine
- ASG/STTI Compatible
- For MK23 NBB Pistol
The STTI 28rnd CO2 Magazine for MK23 NBB Gas Pistols is perfect for those winter months. CO2 is much more consistent than green gas in the cold weather, every sneaky sniper needs these mags for their trusted sidearm during those cold skirmishes. It is compatible with the STTI ST-23 non-blowback pistol but also fits in other brands of non-blowback MK23 pistols. It is constructed from a tough Alloy, looking identical to the standard MK23 magazines, and holds a total of 28 BBs.
The CO2 compartment is inside the shell and is accessible from the bottom. To open it, simply undo the bottom screw with an Allen key. With this done, you will see the CO2 capsule space inside, here you can pop in a 12g CO2 capsule (we recommend adding a bit of silicone lube to the top of the capsule), tighten the Allen key screw back down and you're good to go!

This holster does not include a mount but is compatible with any 30mm diameter toothed rotary interface commonly found on holster and mag carrier paddle mounts. Compatible mounts include the Amomax Shoulder Harness, the Amomax Drop Leg Plate Platform, the NUPROL MOLLE mount and the NUPROL Drop Leg Platform, as well as a plethora of different Novritsch Holster Mounts.
