I just got off the phone with the head of LE sales/armory at colt, And asked about the 6940 and got some great info he said I could share!!!
1st. the FCG pins are spec on this model, it will start the change over to all normall trigger pins. Also the 6940 is meant to replace the 6920, the idea being you dont have to spend extra on a rail, BUIS ites, etc. The bottom does come off like said and the new special barrel nut is a lot easier to remove the barrel.
While i talked to him. He told me that yes, colt made all of their major components and always have, that means the lowers too, cause I asked. All civilian guns are made off the same line, there is no extra plant, factory or line etc for civilian sales rifle.
he told me the 1020 will not be made cause the government told colt they didnt want a piston and colt made one and tested it to find that is had no advantage over DI and even was worse at some things He told me it was just a fad that will pass when all the other companies pistons started seeing the problems colt found in them years ago. ALl civy rifles are tested to the same quality as military guns. he said colt made combat weapons for battle and the men who use them. Fit and finish is not their priority. And of course as we all know, Other companies guns are different because thery dont know some of the tricks colt knows about how to make a true combat rifle.
as for a debate in the retro forum. the sporter slabside lowers where not A2s machined to not have the mag fence, colt atually ordered A1 type forgings up until the id 80s and went to A2 when they ran out of A1 cause it was easier to use one and the difficulty in making large hole lowers in A2.
He told me how the front site locked up with spring tension and lock washers etc, but it was a bit more than my simple mind understood
thereis more but I am so excited I am having trouble remembering it all. i will post more when I can.
He also told me he use to post here and is a member but stopped posting about 3 years ago, after too many guys tried to argue with him and tell him he was wrong about how colts are made
He does still lurk here though and I told him my screen name and told him he is more than welcome to post in the colt forum and he would be more than welcome, so I want to show my thanks to him for is time. he spoke to me for almost 45 minutes.
now that the FCG pins are going to be spec, what are the haters going to gripe about?
