just received a CZ83 from AiM Surplus (whom I've purchased from before) - 1st thing I noticed is that the leftside Mag Release button "doesn't" release the Mag and the rightside button will, with difficulty, release the Mag but it doesn't "free fall" from the Mag Well - I've gotta grab and pull it with my fingertips and then it will come out but it feels like it's being scraped along "something" and there's a lot of resistance
I sprayed the exposed parts with Brake Cleaner then wiped off - have oiled the entire area of the release mechanism - will let that "sit" and might possibly go after the area with more Brake Fluid and a toothbrush (might)
will take it by a local gunsmith when they're open on tuesday and see if he's got an opinion - hate the idea of having to return it to Aim, but.....
so, any suggestions.............thanks
