Abu american its good that you are that much aware of it so in self defence it is always better to know how the weapon operates.

I did a lot of practice with G3 which has a caliber of 7.62 mm on an army pratice shooting range in Pakistan, it takes a lot of time to adjust your target with recoil.I also used AK-47 (which i consider is the best) but G3 is very different and more accurate at long range.

The cops there in USA use maximum M4 rifle maximum ,not a weapon larger than that becasue they woont need it in 99% cases. If a robber comes out to pocess AK47 then they are in deep trouble.

Yes Brit expat is right but i dont want to go against women becasue i wrote somewhere in another forum as well it is better stay behind than contesting them :-).
