Hi there folks, I have a dumb question about my new Colt 6721 carbine. I was just looking it over and noticed that the two Fire Control Group pins are sliding quite freely back and forth in the receiver with just a little finger pressure. Is this normal?
I noticed this while pulling the trigger while the gun was uncocked (already pulled the trigger on to "uncock" FCG). As I sat there watching and pulling the uncocked trigger back and then letting it up, I noticed the glean of oil weeping in and out of the pin closest to the mag release.
At that point I went to wipe the excess oil away from the pin and it immediately started to drift to the left. The rearmost pin slides some but not as easily. When I recock the action, the pins go quite tight again and cannot be moved my hand.
hatMy carbine was last fired at the factory (I presume), as I've not had a chance to go to the range yet. Also, I noticed that there is a moderate amount of lubricant (a light oil of some type) continually oozing from the action around the pins, charging handle, take down pins and ejection port to a lesser degree.
