Love it
I just did my first upper receiver build, using this receiver. Stern Defense 9mm barrel and BCM handguard. Everything fit perfect. The upper has zero wiggle mated to a Type-A lower receiver. Will buy again.
Bad Attitude Forged M4 / A4 Upper Receiver
- CNC Machined from a 7075-T6 forging
- Mil-Spec Type Type 3 Class 2 anodizing
- Dry film lube on the interior
- Lugs held to the high end of the spec to help with a snug lower fit
- 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.

Excellent Upper
If you want an upper from a reputable source, you can’t go wrong here. There is some minor pitting in a couple of places that you have to get REALLY close to see, but the finish is perfect and tolerances are TIGHT! Very happy for my milspec build.
