b.a.d. or no? (magpul battery assist device)

Post by cemoulton » Fri Oct 12, 2012 12:05 am

I haven't used one and can see several pros and cons. What do those of you who have used them think?
My main concern is extra leverage on parts that were never meant to withstand any real measurable amount of leverage and possible bolt hang ups.

b.a.d. or no?

Post by Recon101 » Fri Oct 12, 2012 12:11 am

Are you referring to the Magpul B.A.D. lever? Mine has survived a deployment and I never had any issues with extra stress on the paddle. When the blood is pumping I tend to slap that paddle near inside of the upper receiver anyway. The Lever just made it quicker to re hot the chamber. Only issue I ever had is the vibration from firing loosening the Allen screw that holds it on. A pin head sized drop of loctite blue fixes that.

I read about it, and liked it. My Dad showed me his on his AR, and now I love it.

The sole reason I have one is that it assists in malfunction clearance. Other than that, the only other time I use it is making the weapon clear because I don't have to let go of the grip. Is a very lightweight part, and the problems I suspected I might see haven't happened. As with anything with a screw, I regularly check it to make sure that screw hasn't moved. You can do that with a paint pen witness mark. Its not for everybody, but since I found it didn't interfere with previously trained techniques, I've kept it.

All depends on what you are used to and trained with. I can see how they can make manipulation easier and faster but at the same time since I was a kid all I've used is the bolt release. I can operate it without even thinking about it so I see no need at this point to re-train myself how to use a BAD.

I like them and have rocked one in the stan. Makes locking the blot back immensely easier with no real negatives that I am aware of.

I walk past them everyday at work and have been looking for either an excuse to try one or a reason not to. So far I just can't convince my self that they solve an actual problem.

The best thing about the bad IMHO, is that it gives me more ammo against the "you can't do 'X' in a fight because its a fine motor skill" crowd...

I don't prefer them, but if you like them, drive on.

Seen problems inadvertently locking the bolt mid-magazine, premature release during reloads, can induce failure of bolt locking on a spent magazine.

Seems like those would be the problems of a bad bolt catch. I recently had a problem with a new build, where the bolt catch wouldnt catch the face of the bolt. It would catch the carrier. The problem was resolved with a new catch. Ive never had any problems with my BADs, through 2 deployments and work-ups, and hundreds of range trips since Ive been out. Just this guys experience though

Until somewhat recently I was opposed to anything that wasn't basic, like scopes, red dots, if it didn't didn't really need it to do the basic operation it was just a toy and only people who wanted to cut corners used them

Then I had a epiphany, better living through technology, use a scope, red dot, GPS, ebook reader, any that helps you to do something better is good, provided that if it breaks you can still do the task without it.

No, it would most likely be indicative of weakened mag springs (mag spring doesn't exert enough upward pressure on the follower to engage the bolt catch)--except, for a couple reasons:
1) Seen this with brand new magazines (once with brand new mags on a brand new complete LMT...)
and
2) the problem (mags not locking back) immediately corrected itself once the BAD lever was removed.

If the gun runs 100%, then you add a widget and it doesn't, it's probably the widget. If once the widget is removed and the problem doesn't exist, it's 100% the widget.

This is a problem (mags not locking back) that is seen across the board with enlarged/enhanced bolt locks/releases (BAD, Phase 5, or otherwise).

I'm not the only one who has seen these problems dozens of times first hand. There's a thread on M4C called, 'Why does the BAD Lever suck?' which goes well into detail about all of the above and more.

I much prefer my Gucci RevEng mag release as a solution. Next SBR will be built on a Lancer L15 or Legion lower /w another RevEng mag release.

and I'm not saying that everyone has seen these problems, just that many many have. Sample of one versus sample of thousands etc.

Nope.

What is the "RevEng"?

I have no problem releasing the bolt in the traditional way in fact it seems very natural and the built up muscle memory takes care of it with out thinking.

Now locking the bolt open/to the rear on the other hand has always seemed cumbersome and awkward. Not that I've really practiced it often or had many failures that required locking the bolt open/to the rear. magazines with weak springs have caused the only failures of this kind for me. Now I just don't buy cheap mags and destroy mags that cause me greef
