  1. Love or hate 5 Star Review

    Posted by 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.

  2. Needed On Every AR 5 Star Review

    Posted by 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.

  3. Very Good for a B.A.D. lever. 5 Star Review

    Posted by 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 !

  4. AR essential for righties, must have! 5 Star Review

    Posted by on 23rd Oct 2017

    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!

  5. High Quality Product 5 Star Review

    Posted by on 5th Sep 2017

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

  6. Pretty good, but needed work. 4 Star Review

    Posted by 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.

  7. Now all my friends want one 5 Star Review

    Posted by on 17th Jun 2017

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

  8. First AR, already spoiled. 5 Star Review

    Posted by 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.

  9. No AR without it! 5 Star Review

    Posted by 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.

  10. Why did I wait so long to buy this? 5 Star Review

    Posted by on 31st Dec 2016

    I've seen all of the great reviews for the bad lever, but I was still skeptical. My hands aren't extremely big, but I do have long fingers and I was afraid that this lever would get in the way more than it would help. Boy was I wrong, it's placed nicely in the trigger well where my trigger finger could easily maneuver around it. Once you use this lever, you won't ever want to go back to locking/releasing the bolt the old way anymore. Love this lever!

  11. It's the original and still the best! 5 Star Review

    Posted by on 27th Oct 2016

    Have it in all my ARs; makes locking/releasingT the BCG a breeze. Wing tactical have the best price and fast shipping!

  12. Pretty cool 4 Star Review

    Posted by on 17th Sep 2016

    I think it's a cool mod, only down fall, it has a lot of play.

  13. Must Have! 5 Star Review

    Posted by on 10th Sep 2016

    A buddy of mine adds this to all his builds and recommended it. I added this to an existing stock rifle with some Strike Industries furniture and it's like a brand new rifle. Took it to the range and the first thing my brother noticed was the BAD lever and said this is amazing. Installs in less than 5 minutes , makes loading a new mag easier, no need to charge it just tap the lever while still mounted and you're good to go. Must have, will order for ALL builds.

  14. awesome 5 Star Review

  16. Short Screw Stripped Threads 2 Star Review

    Posted by on 7th May 2015

    First impression of the product was good solid feeling construction, until I installed it. I installed it and locked the bolt back and used the BAD to release the bolt. I noticed it instantly came loose on the bolt release. Upon further inspection I determined the provided screw was not long enough to grab all the threads on the rear plate, and the threads had stripped. I then used vice grips to hold the two pieces together in an attempt to squeeze the plates together so the screw could grab the remaining threads, no luck, the screw was just not long enough.

    Using a Rock River Arms mil spec upper parts kit (bolt catch/release , dust cover and forward assist including roll pins, springs...etc) on a Tactical Machaining stripped upper.

  17. vary usefull, 4 Star Review

    Posted by on 23rd Mar 2015

    I have installed the BAD leaver to all my rifles. It's quick to install, easy to operate, while keeping the weapon pointed down range. Your hand stay on the grip while the charging handle to actuated with support side hand.

  18. great price, very quick delivery! 5 Star Review
