Research notes
The 277 was developed by Mad Dog Shooting Systems and is based on the 5.56 NATO case necked up to 6.8mm. Any existing AR platform can be used with just a barrel change. The 277 Wolverine is basically a hybrid cartridge between the 5.56 NATO, 6.8mm SPC, 300 Blackout and the 7.62x39 AK-47.
