The other day, whilst picking up a 12 gauge i got to handle the gsg-5 mp5 type rifle. I havent shot it, but the qaulity is very good and soild not cheap plastic crap like i thought it would be. After some research on the net, the barrel even has same rate of twist has the original HK (6 grooves) and having a 16inc barrel and in .22 should be more accurate then a 9mm. But as i havent shot it can anyone tell how this thing shoots??
