First off, let me say that this gun is AMAZING for the money! Right out of the box, this thing is mean. Even though mine is the basic version, it EASILY goes through the bottom of a Coke can and wil totally shred cardboard. This gun (once you get the hop-up tuned) shoots EXTREMELY accurate, even in alittle wind. The iron sights are a perfect fit for the gun and having the 2 different size apperatures helps in all enviorments. The hop-up works great, but it took me about 75 to 85 round to get it ABSOLUTLEY PERFECT, and yes it can be absolutley perfect. The barrel is 6.04mm which isn't super tight-bore but close (CA's are normally 6.05 or 6.06mm stock). Nothing on my gun wobbles now (had to send it back because the spring guide was stripped which allowed the buffer tube to come off) but now it is rock solid steady. The rate of fire is crazy high and accuracy isn't affected at all, it looks just like a solid stream of BB's coming out of the barrel.
