ICS throws in there contender for this not so common model and what a contender it is. It comes with some very realistic markings which results in an extremely realistic Airsoft version that is properly scaled 1:1 and with exact real steel dimensions. This gun is also extremely rigid and stiff.
Although including a significant portion of metal, the material used is very dense, strong and weighty, adding to the feel of the gun making feel less like a toy and more like a serious tool. The ergonomic compactness, rubberized pad on the plastic folding stock and smooth facets and lines make for a 'SWAT' length weapon that leaves little to be desired for the aspiring ninja style of player. The mock charging handle can be pulled back to reveal the rotating hop up unit.
The weapon comes with a short style 400 round hi cap magazine of the normal kind. The layout of the mass of this weapon is such that when shouldered with stock extended the user may find it front heavy. With stock folded, the weight centers on the front of the receiver, right in the middle of the weapon, a very balanced setup when moving though confined space with a compact weapon. The drum sight style backup irons sights add yet one more minor eccentricity which harkens to a brotherhood of proud non-Armalite weapons. Also features fold-aside trigger guard.
The ROF is decent out of the box when you use a 7.4V Lipo battery, a little higher then average and at 400 fps it is squarely in the region of skirmish ready but of course should you find the desire to modify beyond the norm then its compatible internals will be more then accommodating when you turn to Redwolf custom services to hook you up. That said, 400 fps with a decent rate of fire in a weapon of this sort is nothing to scoff at, more then enough for a close to mid range assault type AEG.
If you are in the market for a SIG 55X series weapon then ICS is a serious contender. The various different versions replicate different type of SIG 55X with their varying lengths, colours and details to suit different needs and tastes.
