Nevermind, figured it out.
Hey folks, I have a pre-ban Colt SP1 with a large pin lower and a small pin upper. I have two different offset screws, one is the standard Colt offset screw and the other is made by DPMS with a larger screw head. Both yield the same problem... Is there some kind of trick to these things? I install the screw and I can "open" the upper a couple times but then it will be unable to close. It's like the pin is shifting orientation and throwing the position of everything else off. When it's first installed I can still operate the rear takedown pin without difficulty (it's not binding or anything). Is there a specific rotation of the pin that I can install it in that won't yield this problem, or can I do something to keep the pin from getting out of position, or some combination thereof? Please, no "buy something else" comments  , I live in a ban state and I wanted a pre-ban rifle 
Any help on this would be GREATLY appreciated

I have the same problem with the offset pin. If you pivot your upper/lower apart, you are almost guaranteed to have the pin not allow you to put them back together without turning it a slight bit with a screwdriver. It's like it binds up and won't allow the receivers to come back together completely. I think it's just the nature of the beast.
Does that describe the problem you were having? |
