This is kinda ridiculous if they actually watched all the vid's they would see on the first
M14 vid a BB came rolling by the camera at around 0:18. Seems to me a lot of accusation before all the "evidence" is reviewed.
Personally what Ive been thinking for my you tube vids is put a disclaimer on them. Like The "weapons" shown are air guns that fire 6mm BB's the are incapable of accepting real bullets.
