EBR and BAD Levers

[penciljockey]

I currently have a Magpul BAD lever on one of my AR's and it never fails to lock the bolt back when the mag is empty. My other build has a Phase 5 EBR and it never stays open on the last shot. I've been wrecking my head trying to figure out the difference. Someone suggested that the weight of the EBR and the tension of the bolt catch spring is causing a timing problem.

Just wondering if any of you have this problem and if anyone of you have heard that using a weaker bolt catch spring or cutting a few coils off to shorten it remedies this problem?

i have a phase 5 and the only time it doesnt lock back is when whomever is shooting hits the lever with their trigger finger... but it works fine for me... could it be that that phase 5 sits a little lower in the trigger guard so your binding it with your finger when you release the trigger?

I have the Troy Ambidextrous Bolt Release. The only time I had the same issue you're having is when it became a little loose. Ever since I tightened the screw and put loctite on it, I haven't had a single issue with it. Maybe this is a solution that might help you.

Have you tried different mags?

Swap the levers and see if they still do it.

No it's clear of the trigger.

Well my Phase 5 is the one piece kind in which the bolt catch and EBR are one piece.

That's the thing, I had a Magpul BAD lever on it and since my upper is a Vltor Billet people told me the BAD lever doesn't work with anything except standard uppers. So I swapped it out thinking that was the problem.

I had a clearance problem with a BAD lever on a Carbon Bushmaster upper. It was a little wider where it seats against the lower, and the bolt would lock back when I still had rounds in the mag. Changed the upper and no problems.

The Phase 5 EBR I have seems to fit perfectly on the Vltor and it does lock back manually when there's an empty mag in the chamber. I'm thinking it's a timing issue. I cut the bolt catch spring about 2 coils, which still leaves it with plenty of rebound tension. I'm thinking the added wait slow the timing and the bolt just misses it. I'm hoping this will work.

My friend was having problems because the bolt was outrunning the catch because of the added mass of the lever. You may be overgassed or your buffer may be too light.

I'm using the JP Silent Captured spring

[penciljockey]

Does a lighter spring make the cyclical rate of fire faster or slower?

[penciljockey]

Anyway if trimming the bolt catch spring doesn't work I'm getting an adjustable gas block

[penciljockey]

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