You understand that you do not need a bump stock to affect "simulated full auto fire" from a semi automatic rifle right? All you need to do is slip your trigger finger through the trigger guard, hook it in your belt loop and push the rifle forward with the other hand until it fires. keep forward tension on it and 30 rds go in about 1.5 seconds.
do we ban trousers with belt loops? or fingers?
there is a Class 3 manufacturer who wanted to illustrate the lunacy/stupidity of the current gun laws and legislation that makes the masses feel good but doesn't prevent anything. . he is a licensed Class 3, title II manufacturer and can legally make automatic weapons. he took a string, yes a piece of string, put a loop in each end and turned a mini 14 into a full automatic. he even attached a metal coupon with a registered serial number to the string. He then took a piece of coat hanger and made a simple couple of bends in it and serial numbered it also. put it in a registered lower and ran full auto with it. do we ban coat hangers?
point is, full auto fire is easy to do with any semi automatic mechanism from an AR15 to a Remington model 742 Woodmaster.
