I have a slight problem. I bought a very used pre ban Essential Arms J15 lower reciver recently. I got a Stag parts kit and started assembling it last night. Everything went together fine except the bolt catch. The problem was strange though. The bolt catch spring and detent when placed in the hole are flush with the outside of the hole thus not doing a damn thing to keep and tension on the catch. Anyone ever heard of this kinda problem before? Yes I used the correct spring before you ask. I am drawing a blank here, possible solution is trying to find a longer spring somewhere (where?) or putting a spacer into the hole.

Also, couple quick questions on EA Arms recievers. This is a cast reciever, was it ever annodized? It doesn't appear it was. Also the markings are engraved on it, I thought they were raised on cast recievers, the SAFE and FIRE are marked as they ususally are on other AR15's, I was under the impression SAFE was written vertically. Not complaining if the previous owner had them engraved, just curious.
