The above video shows the infamous Chainsaw bayonet. I must say that this is a pretty rare bayonet. I cannot say I’ve ever heard of this idea, but as you can see it does seem like a cool one. If the motor was stronger I think it would be even cooler. Maybe he could just add a full on chainsaw to the rifle. The guy was offering to make this bayonet for other people so if your interested here’s the link: Rare Bayonet Info.
