Next up from TM is the Colt M733. This is the carbine assault rifle best know for it's appearance in BlackHawkDown. Due for release sometime in March this new Colt variant is roughly 10cm shorter than your common garden M4 but comes with an A2 frame. Your guess is as good as mine as to what TM will do to this release to make it special/different - remember nearly all of TM's releases come with some form of innovation (camo paintjob maybe?).
