The Gold Standard


If I had to choose a carbine upper, this would be it. All Colt (except rear sight is Magpul). Chrome-lined, cold hammered forged barrel. Buy one to stash before what is remaining on the civilian market dries-up.

You get what you pay for!


Excellent upper, was everything I hoped for. If I could buy another I would. Very comfortable to shoot, well balanced as far as weight... all in all I was impressed. Buy one if you can, before they discontinue this model completely.
