I'm suspicious of this story....100% lol. The bolt needs to cycle for the gun to fire properly AND.....with airsoft BBS being so small any barrel attached to the gun would be too small (bore too small)for the bolt to cycle through. Not to mention the feeding of the BBS down the feed neck and the logistical problems that creates.
