Tokyo Marui SAIGA-12K Gas Blowback ITP Groza-12 Conversion Kit in Black (B126-BK)

If your Tokyo Marui SAIGA-12K isn't unusual enough already, the ITP Groza-12 Conversion Kit takes things several steps further. Designed specifically around Marui's gas blowback shotgun platform, the B126-BK converts the familiar SAIGA layout into a compact bullpup configuration inspired by the Russian OTs-14 Groza. This isn't simply a new handguard and a few cosmetic panels either. ITP supplies the structural bodywork, relocated trigger components, carry handle, outer barrel and other hardware needed to fundamentally change the layout and handling of a compatible SAIGA-12K donor gun.

The main structure is precision CNC machined from 6061 aluminium, giving the conversion the solid, purposeful feel you'd expect from a premium aftermarket kit. Aluminium keeps the assembly rigid without resorting to excessively bulky components, while the machined construction allows the various sections to fit together with greater consistency. Finished in black, the angular bodywork works particularly well with the SAIGA's existing controls and magazine, creating something that looks less like a modified sporting shotgun and more like an experimental Russian close-quarters platform.

The biggest change is, of course, the bullpup layout. Relocating the trigger forward of the action allows the SAIGA's working mechanism to sit much further back in relation to the shooter. The result is a considerably more compact package without simply chopping away the character of the original platform. For CQB players, that shorter footprint can make the converted airsoft gun much easier to bring around door frames, negotiate corridors with and manoeuvre through confined structures. It still has the visual mass of the SAIGA, but without quite so much rifle sticking out in front of you.

Moving the trigger forward requires rather more engineering than bolting on a new shell, which is why ITP includes a dedicated trigger system and trigger control bar as part of the conversion. These components provide the linkage between the relocated bullpup trigger and the original operating system. A slide skirt, dummy gas valve and other installation hardware are also supplied, helping the finished conversion look like one coherent design rather than a SAIGA wearing an aftermarket costume. The underlying Tokyo Marui gas blowback system remains the heart of the donor platform, so you retain the mechanical cycling and feedback that make the SAIGA-12K such an entertaining airsoft shotgun.

Up top, the adjustable carry handle is one of the kit's defining visual features. It reinforces the Groza-inspired silhouette while also providing a practical sighting arrangement, with low, standard and high positioning options listed for the system. The integrated modular top rail gives you space to configure an appropriate optic setup, so the conversion doesn't lock you into purely old-school iron sights. You can keep things relatively clean or build a thoroughly modern CQB configuration depending on how far down the custom-build rabbit hole you fancy going.

The front end continues that modular approach with a 1913 Picatinny handguard interface. This gives you a familiar mounting standard for compatible grips, lights and other airsoft accessories without spoiling the overall bullpup shape. QD-compatible sling mounting points provide additional options for carrying the completed build, which is particularly useful on a platform designed around compact handling. The folding stock butt pad assembly at the rear provides a more defined contact point when shouldering the converted SAIGA while keeping the back end suitably tidy.

ITP has also designed the Groza-12 around AK GBB-specification pistol grip compatibility. That's a useful detail for anyone who enjoys fine-tuning the ergonomics of a custom build, as it provides considerably more choice than a completely proprietary grip arrangement. The supplied pistol grip gets the conversion up and running, while compatible alternatives allow the shape, angle and appearance to be changed later. Between the grip interface, Picatinny handguard and modular top section, there's plenty of scope to make the finished SAIGA distinctly your own.

The B126-BK is intended as a conversion kit rather than a complete airsoft gun, so a compatible Tokyo Marui SAIGA-12K GBB donor platform is required and is not listed as part of the package. Installation is also more involved than changing a stock or attaching a rail, as you're altering the physical control layout and fitting a mechanical trigger linkage. For owners comfortable working on premium gas blowback platforms, the result is an exceptionally distinctive Groza-inspired SAIGA build with CNC 6061 aluminium construction, practical accessory interfaces and genuine bullpup ergonomics.
