The BAD-ASS Loses Some Weight

The race to the bottom has been running in earnest for the last few years. Various manufacturers have been vying to produce the lightest weight parts for Modern Sporting Rifles as the market has moved from heavy picatinny rail systems and barrels to the modular attachment systems and pencil barrels. There are reports of AR-15s being consistently below 4.5 lbs, unloaded using commercially available parts.


Expanding the appeal of their BAS-ASS system (Battle Arms Development – Ambidextrous Safety System), Battle Arms Development has a lightweight offering, the aptly named BAD-ASS-LW. The BAS-ASS-LW system reduces weight over the standard BAD-ASS by removing weight from the steel safety/selector barrel and by skeletonizing aluminum selector tabs. Weight for the entire system comes in at less than 1/2 and ounce–.42 ounces.

The BAD-ASS-LW is currently only offered as a 90-degree throw (but I am sure a 60 degree will be coming, as BAD was one of the first to introduce short-throw offerings).  Likewise, only two levers (long ans short) are available at this time. The LW is compatible with all standard AR-15 compatible Modern Sporting Rifles including the larger .308 cousins.


Retail pricing is set at $65. The system is available directly from Battle Arms Development or through their large domestic and international dealer network. Packing includes the steel core, aluminum levers, torx screws, selector detent (made by KNS), and selector detent spring.

  • I want a Lightweight BAD-CASS.

    • Steve

      BAD-CASS is my selector of choice on EVERY new receiver I build!

  • M-Cameron

    $65 to save what?…half an ounce over a standard safety selector?

    Maybe spend $10 and buy some barbells fir your girly arms and spend d the $55 on ammo

      I think the logic is that if you were going to drop your $50-80 on an ambi safety, you can get their light weight one within your budget.

      I put a BAD-ASS on a build. It had about the same MSRP as the lightweight version, assuming I could have gotten similar pricing, I’d have saved half an ounce or whatever.

      • JumpIf NotZero

        I could give a crap about the weight vs stock. It’s the 45 throw ambi that’s vital.

        Personally I like the 60º from Noveske, but all the same.

  • Garmanarnar

    And all these extra machining steps are going to inflate the already ridiculous >=$50 price even higher for a tenth of an ounce savings in weight?

  • USMC03Vet

    Gotta shave ounces off rifles, but when it comes to EDC gotta increase ounces, cuz one is none!

    Bipolar firearm industry is bipolar.

    None of this stuff appeals to me much. The areas to lose weight are the barrel and the receivers, with the hand guards bringing up the rear; nothing else matters much at all. But then, I didn’t exactly come out with a light weight rifle; the medium contour barrel alone weighs 2 lbs 13 oz. But I prefer it to one of those skinny little pencil barrels that look like they’ll droop after a hundred hot rounds.

    After having a custom BAD-ASS-ST on both my ARs I won’t ever go with anything else. I run the crank on the left side and the short crank on the right side. Way easier to engage and disengage with that lever type. Love it.

  • SpartacusKhan

    you can get titanium lower parts from V7

  • Frank Grimes

    If they really want to impress people, they should finally make safety levers that don’t have a massive gap between the lever and the lower.
