Has anyone here tried to use a “bump stock”?
-I have. I don’t own one but have shot one. Almost impossible to keep a constant uninterrupted fire rate without gaps in the firing.
Has anyone else here heard the uninterrupted fire from an M240?
-I have.
The videos sound like a fully automatic weapon. Not a bumpstock AR or AK.
JMHO.
I would guess that this guy had the best quality bumpfire available. I would also guess that he practiced, adjusted, lubricated, etc. Money and a year of planning/practice can do wonderful things for effectiveness. He also had several jams. Instead of troubleshooting, the report is he switched weapons. That was (at least part of) the purpose of so many bumpstock weapons. Apparently, he had the .308 (.308s?) to try to shoot through a fuel tank. The .223s were so he could shoot thousands of rounds without breaking his shoulder. Unlike the larger .308, thousands of .223 are no big deal, no worse than .22LR.
