Tribute AR15 Lower Receiver - NERV

Just like in your favorite video game.  I don't know anything about Evangelion so I don't have anything witty to write.

  • CNC Machined from a 7075-T6 forging
  • Hard coat anodized - Black
  • M4 style fire control group pocket machined to current government prints
  • Manufacturer markings are underneath the trigger guard
  • Model:  UC-M4
  • Manufacturer:  Bad Attitude Department
  • Caliber: 5.56MM
  • Manufactured right here at the Bad Attitude Department.

Note:  We mill the lug pockets for the upper receiver at the very bottom of the specification.  If your upper is at the top of the specification, you will have a snug fit.  If it is out of spec on the high side, you may have to stone the sides of your upper receiver lugs to fit.  This is a feature, not a bug.

Favorite New Lower
Written by Derek on 2nd Dec 2023

The finish on this lower was excellent. Came across Bad Attitude Department after searching for a new lower with a cool roll mark for a new build. It was the final piece and did not disappoint. This lower fit tightly to my upper, even better than my Centurion lower which I got for the same price. Nothing but great things to share.

Fun Lower

Fit and finish is awesome, no issues dropping in a lower parts kit. Rollmark makes all my weeb buddies laugh
