New Colt--Cage code + Square forge
by Nic -
Cage code. Square forge. Quality seems good enough. We've gotten to a point where you really need to trust your retailer when buying parts advertised as Colt. I do happen to trust Primary Arms, so no worries, but the fakes are getting good enough that I wouldn't even consider buying from a less credible source. Stay off the forums. Stay away from the gun shows. Lots of fakes going around these days.
