Toolcraft & Colt Military Contract BCG 5.56

I'm giving 5 stars because it's wetworx, and I don't want to say anything to hurt them... But the bolt, while it is white-dotted, is not marked otherwise...and it does not appear to have been fired. Extractor is marked 13629... The carrier is absolutely... Possibly the finest phosphate carrier I have ever seen...thought the cage code is not as deep as the one in the picture. The cam pin is not to my liking, and extraordinarily tight... I can't make out the plating on it... No comment on the firing pin... I picked this up for an URG-I clone...so I find a marked bolt somewhere else., maybe... If you're getting this for a normie build, replace the cam pin with an np3 one from triarc or other, and you would have a fantastic BCG...
