  1. How is this a lower parts kit? All I see are a bolt catch, safety selector and mag catch. There are a hell of a lot more components in an lpk…

    • I agree Indy Jones. Didn’t even show the parts installed to get a better idea on how they look. TTAG should just label these articles as ads and be done with it.

      • We do label sponsored content. This is not sponsored content. We get paid nothing for this post.

        • You do get paid. You drove eyes to advertisers by those who clicked on this story in hopes that there would be pics and opinions. Heck if you hang out at the LGS with your camera, you could knock off a hundred of these kinds of useless posts a day.

    • You should. This “article” is nothing more than a Battle Arms Development press release. It’s not even a “Lower Parts Kit,” as the industry knows it.

  2. Now, I just finished a lower with Seekins Precision’s parts kit, and that actually has everything but a trigger. Except it needs one more set screw for the ambi safety. If I thought BAD had a complete kit, I might have gotten it instead.

    Really, for all the little upgrades people do on their ARs, I’m surprised there aren’t more kits that are “upgraded from the start”.

  3. “At a penny over $24.99 they’re not cheap”
    The linked BAD page price for this is $35.00
