I picked up a MAGPUL Battery Assist Device for my M4gery and took that out to A-Zone to test out between teaching classes yesterday, I have to say it rocks! I found it very easy to use and switch over to from using the bolt catch to using the BAD. Pretty slick and out of the way. I was a bit concerned about hitting it with my trigger finger but unless I was wearing rather thick gloves, I don't see that happening.
I didn't post photos or video as there are much better demonstrations out there from MAGPUL themselves and all I had was my crappy cell phone camera.
FTC DISCLOSURE: MEGABYTE ME! I paid for this and was in not way compensated by MAGPUL or any of their dealers for the evaluation of this product. HELP HELP, I'm being repressed.
