I built this frankenstein a while back, shot it a few times, got bored.
Parts are:
https://liveqordie.com/honey-badger-handguard-kit/ $299
https://liveqordie.com/honey-badger-barrel-assembly/ $425
https://liveqordie.com/honey-badger-barrel-nut/ $50
https://liveqordie.com/honey-badger-turnbuckle-assembly/ $40
https://www.aeroprecisionusa.com/m4e1-threaded-stripped-upper-receiver-black $150
BCG ~150
CH: $80 or something, I don't remember
Cherry bomb: $55
Aero Upper: $104
Probably forgetting some small hardware/parts kit.
Total cost of the upper build: $1353.
I'm selling the upper only for $1000. Only the upper. Not the lower. Not the optic. Just the upper.
I will accept trades on the whole setup, however. The total cost of the build is probably ~1700. CMMG parts kit, Aero M4E lower. I accept trades in the ~1300 range.
If you have something in 300 PRC I will come up with cash on my side.
