Description

Bad Attitude Department AR15 Stripped Upper Receiver - Clear Anodized

********THERMAL FIT********

  • CNC machined from 7075-T6 aluminum forgings
  • Mil-Spec Type Type 3 Class 2 anodizing - clear (Clear anodizing varies in shade and texture)
  • Fits all standard Mil-Spec dimension components
  • Custom engraving available
  • These are thermal fit receivers.  You will need to heat the receiver in order to install your barrel
    • Heat the receiver in an oven set at 250*.  Install the barrel and let it cool to room temperature before you install the barrel nut
    • GENTLY heat the front of the receiver with a propane torch.  Do not overheat the receiver.  You need only to heat it slightly to install the barrel.  Install the barrel quickly and let cool to room temperature before you install the barrel nut.
  • Bad Attitude Department is not responsible and will not replace uppers damaged due to improper heating or installation.  If you run in to a problem, let us know and we can help you out.  

If added, T-Marks will be laser engraved

For custom logos, please check our our BCG page for examples or email us first with your logo idea.  Logos will only be placed on the top rear of the receiver, just above the charging handle.  Deep engraving destroys all anodizing and usually requires a coating or color fill to protect the exposed aluminum.

A note about clear hard coat anodizing - it is not an even color as it is effected by the aluminum beneath the anodizing as well as the way the light reflects off the finish.  Upper and lower receivers may not match at all in color.  Unlike anodizing with black dye, it also does not cover minor imperfections that would normally not be seen.  Shade will vary on each receiver.  It is every bit as protective as hard coat anodizing with black dye.

    Has to be one of the best uppers I've worked with. The fit and finish is amazing. Matches their lowers perfectly! Tight tolerances makes for a perfect build. Highly recommend purchasing!

    Got this lower about a week ago and went to work putting it together...so smooth! Less upper lower flex than my Knights! Highly recommend them for any builds.

    Skip the T Marks

    Posted by Daniel on 20th Apr 2025

    Nice light color, matched FCD parts well. Had a few little pits on the left side, not a big deal. Not a fan of the T Mark Font and small size, knocking off a star for that.

    Perfect match for the low-key lower.

    Posted by Kevin on 4th Feb 2025

    The color matched the low-key lower perfectly and they lock up very tight. I understand that the clear anodized doesn’t hide imperfections as well as black anodized but I feel like the one I got should have been a blem due to a long imperfection along the side. I think BAD has become my default for uppers and lowers because the overall quality is great.
