Some parts came in the mail today. So I dug out the Spikes lower (blem) that I bought 5 years ago. They said it had a slight discoloration in the finish. I couldn't see it then and still can't see it.
I tried fitting the new billet upper to the lower and the front lug barely fit into the lower. Closed it up and tried to install the back pin. Went through to the far side of the lower, but no joy. I've squeezed the upper and lower pretty hard and pushed and hard as I can on the rear pin with my thumb.
I shot an e-mail off to the supplier, but won't get an answer before Monday. They will probably say it's the lower, and I don't want $20-30 in postage back and forth. I'm thinking of taking a few thousandths off the shoulder at a 45* angle on the pin. Least expensive part to replace.
Any thoughts before I fire up the lathe or grinder?
thanks,
CC
