EBR and BAD Levers

[prometa]

Has anyone had any experience with trimming the bolt catch spring?

I haven't trimmed it, but did have a related situation on a CMMG .22 dedicated upper. When I installed their bolt catch adapter into the lower, it would catch if I used the lever, but not on an empty mag. Turned out the follower wasn't sprung strong enough to lift the mass of the adapter, bolt catch, and spring. CMMG included a different bolt catch spring that was the same length but fewer winds (weaker), and installing that solved the problem.

Ironically, without the adapter, it would catch on an empty mag but not using the catch directly.

So in theory it should work. I'll keep you posted. I'm trying it out this weekend. If it doesn't work I guess I'm changing to an adjustable gas block and be done with it. It may be the BCG rebounding to quickly for the catch to hold.

Well for those interested it didn't work. I'm going to change to an adjustable gas block.

Ok here's an update. The adjustable gas block solved the problem perfectly.
