The G&G SMC9 is based around 9mm real steel pistol conversion kits which are becoming increasingly popular in the US. Pistol conversion kits popularity stem from being able to use your pistol for longer range shooting in a carbine platform whilst having a high-capacity magazine which utilises pistol ammunition which is cheaper than rifle ammunition. G&G have designed the perfect airsoft gun which utilises a conversion of the GTP9 airsoft pistol so that you have the ability to shoot at longer ranges and on full auto, whilst still keeping the compact nature of the pistol platform.

The G&G SMC9 is a full kit which means it comes with the GTP9 pistol already installed which allows you to use the gun straight away! As a carbine conversion of the GTP9 this airsoft gun has an extremely compact design whilst offering full-auto firing capabilities making it perfect for room clearing in CQB games. The SMC9 is made from durable polymer and metal and features a 7” M-LOK handguard which allows you to add M-LOK compatible accessories. The SMC9 also has an upper 20mm integrated rail system which allows for the attachment of optics or other accessories such as a PEQ box.

Everything on this gun has been designed for user compatibility and ergonomics so you will find an ambidextrous charging handle, fire selector, slide release and magazine release on the SMC9. The chamber cover is also selectable for right- or left-handed shooters, whilst the gun also features a button and trigger safety which can be operated with either hand. The SMC9 features a folding stock which is held in place by strong magnets when you want to keep the overall length of the gun compact and due to its lightweight nature, it is easy to shoot with one hand in this compact configuration.

The SMC9 also has a floating barrel design, optional front and fixed rear sling points, flip-up adjustable front and rear iron sights and a 14mm CCW threaded outer barrel which allows for the attachment of a suppressor or tracer unit. The G&G SMC9 is easy to disassemble and internally you will find a 120-click adjustable hop-up for fine tuning your BBs trajectory, G&G enlarged gas valve and internal parts made from ceramic which helps improve frost resistance from gas cooling. The SMC9 also comes with a 50 round cold resistant magazine, hop-up adjustment tool, optional pistol backstraps, optional sling point and even a speedloader which means you have everything you need in one box to start using your new G&G SMC9!

If you are looking for a gas airsoft gun which is perfectly suited for both CQB and outdoor airsoft games and provides the long range of a rifle whilst keeping the compact design of a pistol, then the G&G SMC9 is the gas blowback airsoft gun for you!
