New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

Ideal for long-time veterans of airsoft as well as those new to the game, the Classic Army Nemesis series of AEGs was designed to give players the ultimate weapon to take down the opposition. Classic Army took the best parts of their Scarab line and forged these pieces into your enemies' worst nightmare.

The MK18Mod1 is a perfect blend for both close quarters and midrange work since this 10inch rifle is short enough to be maneuverable in compact spaces but packs enough punch for longer ranges. Bore up internals, a one-piece metal hop up featuring a locking wheel and a tight-bore barrel ensure that you can propel your choice in BBs out to a significant distance that rivals the more expensive competition.

Internally, the rifle has the updated G2 gearbox with a brand-new electronic control system, 9mm bushings, 6.03mm tight-bore barrel for enhanced accuracy, a 31k high speed / high torque motor and a quick-change spring system. The ECS eliminates traditional trigger contacts and uses a programmable micro-switch trigger that allows for three or five round burst fire and semi-locked function. The Nemesis Mk18 will shoot 390-400 fps using 0.20g BBs and combined with the new motor it can provide up to 26 rounds per second on a solid 11.1v Lipo, making it one of the fastest AEG's on the market today. It has a true quick-change spring system through the back of the receiver by simply unscrewing the stock tube saving you precious time so you can quickly and easily upgrade or downgrade your spring to change the power level to adjust to any environment.
