Well it was bound to happen. You tinker enough and eventually you break something. I have a really awesome Franken Pam 089 with gen dial and hands. It has an H-factory Crystal with fantastic AR. The only problem was, the mag on the cyclops was such that it made you dizzy whenever you checked the date. You guys know what I mean, it's only clear when you close one eye. So I found a replacement on eBay. Got it installed (almost) and loved it. The replacement had a great AR and a perfect cyclops. Awesome!!!
Only problem was it stopped about 0.5 mm from seating all the way down. Of course for my OCD ass that's not good enough so I'll push real hard and get it seated. Oops
So $70 later I have another Crystal on the way. I also ordered a better press and micrometer to check tolerances. Fingers crossed I can get this one in perfect.
