    Thanks, I just saw that. I used the BC from my spare LPK for now.

    I wonder if Magpul had any break while they tested the BAD.

    That's a good example of why I don't use one...

    Sorry to hear about your bolt catch.

    Any metallurgical types here who can give insight on probable cause from those pics?

    And I'm curious how that particular part was made. Cast, forged, MIM...?

    Just curious, you've seen this happen before?

    Its interesting that I see this thread tonight. I just took my BAD off of my duty gun, for this very reason. Not because I broke my catch. But, because after using the BAD for a while, and really considering the way it works, and the increased leverage you can put on the catch while using it, I feared it may cause a failure. I actually figured the roll pin or aluminum ears would fail, or the BAD clamp would loosen or fail, before the catch itself would break, though. I agree, it does seem your LMT catch was most likely faulty, though.

    While I LOVE the ability to manipulate the catch with my trigger finger, I just don't think an add-on lever is the best way to achieve this. I wish someone would come out with a lever that was one piece (BAD lever and catch, in one machined piece). I would consider running something like that. Then again, you would be putting a large, higher leverage lever on a mounting pivot, originally designed for a tiny lever.

    Again, I love the BAD for its intended functionality. I just can't completely trust it on my duty gun, at this point. Plus, I don't want my range guns to be vastly different, so it won't go on those either.

    The version 2 of this comes mighty close...its a one piece that has been welded...

    I can't quite see clearly from your photo, but in my experience the steel will often show a bit of discoloration through part of the break if there was a crack. Probably caused by some kind of inclusion from the molding process or heat treating. My guess would be the heat treating. That's where I've experienced the most failures in hardened steel. That's just a guess based on my experience as a tool maker for the last 25 yrs. Either way I'd bet on a bad bolt catch. Of course the B.A.D. lever hasn't been on the market that long, time will surely tell whether it's going to be more of a liability than a boon. And as hard as you guys run your guns, I'm betting this will be the place to keep apprised of the situation.

    I was thinking this, it seems like a clean through and through break, and iirc that's how an internally defective part breakage was described to me to look like.

    About the B.A.D, I think the concept has been around for some time before Magpul started commercially producing them. I hadn't heard of anything like this till now, more of functioning issues like the bolt not locking back after the last round. I guess we'll see how it works in the real world as it gets more common.

    And yeah, this would be one of the first places to get the skinny on it.

    That still wouldn't solve the problem, if there is a problem, with the breakage.

    I'd be curious to know if anyone else has seen this issue. I can tell you that I sure haven't, and I think I've had a BAD, starting with the prototype, just about as long as anyone.

    For those with concerns about this, but that still want to achieve the lock-back feature for malfunction and other clearances, there is the Boonie Packer Redi-Catch which replaces the hammer and trigger pin and mounts to the side of the gun.

    I don't have a picture handy of the operational side, but this is the mounting side and how it interfaces with the "ping pong paddle".
