Im not going to go back and look through for all the names of the particular questions/comments posted but if they apply to your question/comment Im directing it towards you!
To obtain a full auto weapon they must be legal in your state. In my state all you have to be is 21, pass an EXTENSIVE back-ground check, pay the federal $200 tax stamp, wait a few months for bull**** paper-work and that is about it. If you want a full-auto M-16 (again legally) expect to drop 12-20 THOUSAND dollars! The cheapest full-auto would be a MAC-10 and will run you 2-3K.
Zepplin, are trigger locks required by law or do you just use them?
Viscous_fish, why did you bubba your Romy SAR-1? Man I love those rifles and they should be kept pure! That M-44 kicks like a mule doesnt it? At a gun show a vendor where selling them in good condition for $40 a piece a couple years back and Im kicking my own ass for not getting a few!
The gun with the "cannister" is a Romanian SAR-1 (AKM-47 clone) with a Romanian 75round drum.
