  • Love or hate

    Posted by Bob on 9th Aug 2018

    Yeah, you either love the B.A.D. or you hate it. I love having all my controls (trigger, mag release, bolt release) where I can work them with one finger. Other folks hate the idea for various reasons and feelings.. I have them on two rifles and an AR pistol. I have parts for one more rifle build and will be installing a B.A.
    D. on it also.

  • Needed On Every AR

    Posted by Troy on 30th May 2018

    As a resident of California you try to find ways to keep your rifle running without complications caused by the outlandish features you are required to have on your rifle. With the BAD lever installed it makes holding your bolt to the rear a breeze if you have a fin grip installed. Can’t recommend this product enough.

  • Very Good for a B.A.D. lever.

    Posted by Sandy on 13th Jan 2018

    My son uses a B.A.D. lever on all his AR rifles. When he demonstrated it to me, I tried it on the range. When I installed one on my rifle it allowed much simpler and faster manipulation during mag changes. So now I need two more B.A.D levers !

  • AR essential for righties, must have!

    Just bought a second one for my fiances build I am currently working on. I honestly can not think of any reason not to get one of these for every AR-15 out there, unless you are left handed. Best purchase by far!

  • High Quality Product

    This is my 2nd BAD lever from Magpul, Awesome product, easy install and high quality as well.

  • Pretty good, but needed work.

    Posted by RG on 18th Jun 2017

    Neat idea, but not all bolt catches are the same. Mine was a bit too thin so that when the BAD lever was installed and the screw was tightened, there was lateral movement in the lever and NOT because of slop in the bolt catch pin. I fixed the problem by taking a piece of Teflon sheet (.015" thick) and cutting it to fit into the shallow oblong cavity in the lever. The soft nature of the Teflon filled the gap and the remaining thickness cold-flowed into the serrations in the bolt catch button face, locking it in place. The lever is now tight and works well.

  • Now all my friends want one

    Posted by Ken on 17th Jun 2017

    Installation-simple, price-good, envy of my range pals- priceless!
    Thank you wing tactical.

  • First AR, already spoiled.

    Posted by Unknown on 18th Apr 2017

    This ended up having almost no play for me, pretty solid, pretty happy with it. Really had to tighten it more than you'd think.

  • No AR without it!

    Posted by TK on 24th Feb 2017

    I would not want another AR to be without the BAD Lever. Simply makes for quicker operation for a righty without needing to change shooting grip. I prefer this one over the other I've seen.
