Bad Attitude Forged M4 / A4 Upper Receiver - Prudent Technology

We have a limited quantity of these uppers, machined by Prudent Technology during the time that they were running uppers for Colt & FN.

  • CNC Machined from a 7075-T6 forging
  • Mil-Spec Type Type 3 Class 2 anodizing
  • M4 marked above teh gas tube hole
  • M4 Feedramps
  • Snug barrel fit
  • Fits all standard Mil-Spec dimensioned components
  • Custom engraving available

If added, T-Marks will be laser engraved in white

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.

This is a great fitting upper with tight barrel fit and fantastic anodizing. It reflects the rest of B.A.D. ‘S inventory of stellar quality items and great customer service.
