Did Colt change specs? I have an alleged Colt upper that both taper pins are about 1/8” shallow & not all the way to the smaller end. In other words, they look too short, and the wide head is mangled. It looks like the taper holes wasn’t appropriately reamed & they tried to hammer the pins across?
Looks like Colt is still in it’s tailspin towards the bottom of the heap to me. They were good when they were they only game in town and didn’t have to be. Competition will kill them. Colt is the next Armalite… Squeezing as much juice from the prancing horses as possible before putting them out to pasture.
A friend of mine had very bad experience with Colt customer service taking almost a year with a new rifle that fired a shot & wouldn’t work afterwards. I don’t know if this reflects additional “slippage” is indicative of more Colt issues or something else.
There’s more to this issue than Colt. Reading his other post on the seller, it’s unclear if the pins themselves are Colt or if the upper was assembled by the retailer from assorted parts.
