Re: upper/lower fit
if it wasn't tight it wouldn't be "precision," would it?
most people try to make their sniper rifles tighter, not looser. but if you think that is going to help then by all means give a go and see what happens.

Re: upper/lower fit
mine are the same way. Looks to me on mine the spot making it tight is at the rear rounded edge of the upper.

Re: upper/lower fit
I would have to agree about the rounded edge of the upper.
So what should I do? Ream out the upper hole a little? Sand down the rounded edge of the upper?
IvanR, it's so tight I can't push it out or pull it out with my fingers. It must be hammered out.

Re: upper/lower fit
Did you put a little oil or lube on the pin? Do you squeeze the upper and lower together to take some pressure off the pin when you attempt to remove it (note remove rear pin first)? Can you get another take down pin ti try?
Don't grind the upper or lower.

Mine's no Seekins but it was very tight, like put against something and use the leverage of the forearm to get the rear pin in and tap with a punch and hammer for removal. Shoot the shit out of it and open and close it a few times and it will fit perfect. I think mine had loosened significantly by 1000rnds.
