- High-density polymer build
- NBB Pistol - Very efficient & accurate
- Fits VSR/GBB Inner barrels & HOP-up buckings
If you have a sneaky playstyle, an MK23 belongs in your arsenal! This phenomenally quiet Airsoft NBB pistol has been the sidearm of choice for Airsoft snipers since it was released, thanks to its impressive long-range performance, compatibility with VSR-10-style HOP-up buckings and barrels and its near inaudible muzzle report, especially when the inner barrel extension inside the included suppressor is swapped out for a foam filling.
Famed for its role in the Metal Gear Solid video game series as Snake's primary, as well as being featured in one of the coolest scenes in Breaking Bad, the MK23 is an absolute icon, both in Airsoft and the real steel world. The real MK23 finds its origins in the "OHWS-SOP" project, designed for US SOCOM operators requiring match-grade accuracy and exceptional durability.
Part of the reason the Airsoft MK23 is famed for being ultra quiet is due to its non-blowback action, avoiding the excessive noise of the slide cycling, which also provides the edge in gas efficiency and consistency. For those who simply must upgrade every Airsoft gun they own, the MK23 is compatible with VSR-10 style inner barrels and HOP-up buckings, with access to plenty of specific tuning parts to bring the very best from this already impressive platform!

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!
