Description
VORSK VMP-1M 0.99J GBB SMG – Black
The VORSK VMP-1M GBB SMG takes the aggressive, compact VMP platform and adds something that makes a big difference on the field – a fully adjustable 6-position M4-style sliding stock. Combined with 0.99J gas blowback performance, a 6.03mm tightbore inner barrel and a highly adaptable rail system, the VMP-1M is a seriously capable close-quarters platform with the added stability of a proper shoulder stock.
Powered by green gas, the VMP-1M delivers the recoil, sound and mechanical feedback that makes GBB SMGs so enjoyable to use. Its reinforced polymer receiver keeps weight under control, while steel, brass and alloy internals are used throughout the operating system. The result is a compact and lively SMG that is equally suited to CQB, indoor sites and players looking for a manoeuvrable secondary or lightweight primary for woodland games.

The “Pro” Take
The big advantage of the VMP-1M over the standard VMP-1 is the stock. While the original platform is extremely compact, the 6-position sliding stock gives the M version a much more conventional shooting position. You can shorten it right down when working through tight CQB spaces, or extend it when you want the additional stability of a proper shoulder-mounted firing position.
The magazine-in-grip design is another defining feature. Rather than having a large magazine hanging underneath the receiver, the 48-round magazine sits inside the pistol grip. This keeps the weight concentrated around the shooter’s hands and gives the VMP-1M a very distinctive balance that makes rapid target transitions feel natural.
For a compact SMG, there is also plenty of room for customisation. The 20mm top and underbarrel rails make mounting an optic and foregrip straightforward, while the removable side rails give you even more flexibility. The VMP muzzle system also allows the platform to be used with the VORSK VMP Can suppressor or other compatible barrel accessories.
And of course, being a GBB is a huge part of the appeal. The VMP-1M delivers the sound, movement and recoil response that makes gas blowback replicas so much more immersive than a conventional AEG.
UK Spec & Site Performance
At approximately 0.99J, the VMP-1M is a particularly attractive option for UK players looking for a lower-powered GBB SMG. Its compact format makes it extremely comfortable in CQB, while the adjustable stock provides enough support to make it useful for more controlled shooting in woodland and outdoor environments.
As with all gas blowback replicas, performance can be affected by temperature, gas type, BB weight and general maintenance. Always chrono the rifle in its final configuration using your site’s required procedure and check the
