This is from our COBALT BLUE TRAINING RIFLE model line.  The 416 Super Shortie is one of my favs...More of a PDW than a CQB, this gun, as all of our Cobalt Blue M4/M16.416 Series Training Weapons features full size and weight, working: Bolt, Trigger, Fire Control system with HK Type markings.  Bolt assist works, mag releases, dummy ammo loads in the mag with 5 dummy rounds included.  Please note: LEGALLY, these can not chamber live or Dummy Ammo.  This is the line drawn by the US BATFE, and these guns are 100% compliant with ATF regulations, and all are certified as "Non-Guns".  Super realistic look, they will fool even the experts and are excellent training aids.  Even the Front sight adjusts!  Bolt and charging handle remove as original, and same with the breakdown.  These Bad Boys are even X-Ray Correct, with more info and a downloadable spec sheet available on the Cobalt Blue Website.  www.CobaltBlueGuns.com   Other INERT weapon companies claim to have these, but the patents and trademarks are OURS, and we manufacture them right here.  Accept NO substitutes.  This is a great gun for collection, and movie productions.  Very Impressive.
