built several lowers all with success and thousands of happy rounds down range, last build i did im having a slight problem with,  bolt catch works as its supposed to and holds bolt open on empty mag, but it is really hard to push to drop the bolt, almost as if its rubbing, its a snug fit in the mega lower, but moves freely, like i said with pressure on it, the bolt catch feels llike its very very stiff when pushing

I just built up a Spikes lower with PSA parts kit and kind of have the same issue. The catch feels as though the spring isn't even there. It's tight, and the catch just moves from one position to the next only with "significant" pressure.

But after running some test mags through it...it works.
