WOO! FIRST REVIEW! Alright couple of changes here from the standard G4.
First off: The I4s have a Split-Gearbox design which means it has the breakdown kinda like a real firearm.
Couple of changes with the new ICS Gearboxes; No Pneumatic Blowback System =,( still has the Functional Forward Assist though =)
average velocity 290-300fps
m4/m16 mag compatible
ICS Retractable Crane Stock
Semi / Full Automatic / Safe features
functional Forward Assist
rounded RIS making it easier t grip as you can see the MagPul Angled Vertical Grip in the picture (i got one on my gun ++highly recommended++)
convertible outer barrel
flip up front & rears
I only came across a couple of cons with this gun, but for some people they can be pros too.
the crane stock is unique the wires are arranged in a way to not impede the movement of the stock in all positions however the stock only houses 1 type of battery "ICS Crane Stock Battery" or your gun will NOT work
