I have just installed the Magpul B.A.D. lever.
But now the bolt does not end up in the rear position when the last round has been fired.
I currently use a standard buffer, but I am planning to get a H buffer.
Will changing the buffer help???

Ensure that you don’t have a gas leak anywhere and that you’re using known good mags and full power ammo. An H buffer should be used anyway if you have a carbine length gas system.
Did it run before you installed the B.A.D. Lever?
Everything was running great before installing the B.A.D. lever.
I have also used the Enidyne buffer before, and that ran smooth as well.

Just a thought - if your rifle was running 100% before the addition of an aftermarket piece, it may be the aftermarket piece causing the issue and not some inherent flaw with the rifle.
I would not go modifying a perfectly good rifle when the answer is probably right in front of you.
Very good point.
But it could also something that was borderline working and adding this was enough to cause it to not work. If it were mine I’d try a know good other carrier in it and see what a happens. It could also be running so fast that the magazine doesn’t have enough time to lift the bolt catch in time to catch the face of the bolt. Or so slowly and weakly that the bolt isn’t moving far enough rearward to be intercepted by the bolt catch. Just things to look for.
True as well.
I just hate to see a guy go tearing into a known good rifle.
“It could also be running so fast that the magazine doesn’t have enough time to lift the bolt catch in time to catch the face of the bolt”
I have thought about this myself.
That’s why I thought getting an H buffer might help (slow the cycle down a tad).
You guys think that might be a solution.
(I switched from the Enidyne to the standard buffer when I installed the B.A.D. lever)
I run a carbine length gas system.

IF you changed fro mthe Enidyne to the CAR buffer at the same time then yes, it’s likely running too fast. An H or H2 buffer would slow it back down close to the cyclic rate of the previous Enidine. Since you have the Enidine already pop it back in there and head back to the range.
FWIW, when I put a BAD on my Colt, I had to go from a H to H2 to get reliable lock-backs. When I added a suppressor, it would only lock back about half the time. I went from a H2 to a 9mm buffer and it locks back 100% both suppressed and unsuppressed.
i find it strange that a BAD would cause failures, it is essentially a floating piece of metal.
Well, it adds more weight and stresses on the ping-pong paddle. On one of my two LWRCs, it occasionally causes bolt hang ups when I charge the gun. If you think about it, you’re basically adding more leverage on a pin designed to support just the paddle.
I’m gonna run the B.A.D. through my two carbines for a couple more thousand rounds, if it causes failures, I’ll take it off. Otherwise, it is good kit.
i agree with gotm4 that something was borderline failure but the BAD pushed it over the edge. Theres a lot of BADs purchased on another forum I frequent, I havent heard these types of problems there.
Well if it helps, I have two BADs on a DPMS lower and a CMMG lower both on BCM midlength uppers, and I’ve never had any problems manually charging and getting it to lock on empty practicing reload drills. I’ve shot them at the range and had no problems getting them to lock back on empty. I will try to run it someday in a class.
It sounds like the BAD is slowing down the rise time of the bolt catch. A heavier Buffer should fix this.
yea slowing the rise time of the follower pushing up the bolt catch, does it do this with certain mags? Timing must be really tight if a BAD can slow a bolt catch enough to where it doesnt catch a cycling bolt.
i got same problems time ago…
with the new Pmag the bolt was not lock open…
i try and try and try…
the problem was…the anydine…
probably broke…
i replaced it with a normal buffer and the rifle was ok
The weight of the BAD on the bolt release is probably causing it. This was a concern on some earlier devices. I saw a photo of a BAD prototype that had lightening slots cut length-wise in it. It looked to me in the photo that would affect the strength of the lever.
I fired my AR with the BAD for the first time today, and I brought only 3 mags . It started off fine, but then when I added the suppressor, it locked back fine with a standard aluminum mag, but would almost never lock back with the two PMags I brought. (oh, the irony)
That said, I think the BAD is an excellent piece of equipment, especially for clearing double-feeds. At this point, I plan to check mag-by-mag, and will have sort of a first tier/back up system with them.
those with problems, are yall using carbine gas systems?
Remove the BAD and verify that it runs fine without it. if it does not, then you have another issue. If it does, then I recommend not using the BAD.
Could it be that the B.A.D. is causing the bolt-catch to be dragging on the bolt-carrier? Slowing it down and resulting in failures to lock-back?
