Practice up, then take your M4 and Spring-Action MK IV pistol to the field and take NO prisoners! It's the complete package for Airsoft enthusiasts... 2 life-like firearms all packed up and ready to roll for your next skirmish.
The M4 boasts semi and fully automatic modes to accommodate your conditions. And with a durable plastic body and gear mechanism, you won't have to worry about performance when it matters most! See-through construction shows the innerworkings of the Gun, too... from cogs, to the firing mechanism.
Spin-up: The Spin-up system is available in AEG, Gas and Spring operated models. The basic theory is to put backspin on the BB. When the BB is fired there is resistance on the upper side of the BB creating a backspin. This offsets the effect of gravity, wind power and air resistance and pushes the BB to travel a longer distance.
