    I'd suggest cutting off everything behind and below the box.

    Not that I think the lever should be cut in the manner described, but it won't weaken the paddle unless the cut is made too close to the pin hole.

    How do we know that the problems with the bolt locking back on the last shot is caused by the extra weight of the lever? If the mag spring is good enough to raise the next round into place, it is more than enough to raise the lever

    Oh gee well thanks guys. Never swapped a bolt release before, never checked where the spring was. I do hate guys who suggest magical fixes when they dont understand the system theyre talking about... Shit.

    Still.. Would be nice to see some lighter devices marketed towards guys who intend to make use of it and not its ping pong paddle..

    As for replacing the mag springs, end users would have to replace every mag spring which may prove costly. A single part solution that worked with any and all mags seems like a better idea, but I dont exactly have my own CNC mill.

    Anyhow. Would be nice to see it... All Im saying.

    Ive thought the same. Yet somehow I experience consistent FTLBs with particular springs when using a BAD, and reliable performance when not using a BAD.

    I dont want this to turn into another "diagnose my AR troubles" thread, but if we could begin to understand the true causes of FTLBs with BADs, it would be very helpful.

    Just a SWAG- The BAD lever should be lighter than even a single cartridge. However, if there is some kind of drag at the pivot point (or anywhere else) that could slow down the mag spring pushing the bolt catch into place just long enough for the bolt to over ride it

    I would think any drag from a tighter fit lowers would be more of a factor than the weight of the bolt catch. I have six BADs that all work with looser fitting bolt catches and lowers.

    Your problem is not so much weight as rotational inertia. The bolt latch has to rotate in a short time, the more rotational inertia it has the slower it will rotate. The BADD lever has a lot more inertia than the standard lever. You are not going to be able to reduce the inertia of it by much and still have it function as you want. The trouble is that mass has more and more effect the farther it is from the rotational axis. Imagine you are trying to rotate a barbell bar 180 degrees. It is a lot eaiser to rotate it about the long axis than it is to rotate about the short axis.

    Even so, the moment of the lever would be measured in inch/grams even considering the mag follower is on the short side of the fulcrum (pivot point). If the silly thing were made of steel, maybe. But it's made of aluminum, yes? Even so, it appears the mag follower has less distance to travel to engage bolt lock than it does to raise a round into feeding position.

    I did forget about the bolt hold open device spring. It does add to the resistance but it shouldn't be much

    If you're having problems with the bolt locking back, may I suggest this new conversion which will fix the issue?

    That's pretty clever. Wonder who came up with it.

    Pound meters MistWolf. Milli pound meters maybe. Or micro pound meters. Something like that.
