Best left to a trained professional.
Yes this gun has great accuracy if you adjust it and set hop up right
adjust the hop up on the left side of the barrel put it to middle.
there is no hop-up system on a Crosman C-11.
Aim lower. I am not exactly sure, but try adjusting your hop up
Your hop-up is on way to much. If it is not adjustable, heavier bb's should go straighter. If most guns it is adjustable, so you just need to tone it down. The most common place to adjust the hop-up in an AEG is be hind the bot cover. To expose it just pull back on the charging handle. Sniper rifles often have a small hole on the bottom of the fore grip in which there is a small screw, which when turned with an allen wrench adjusts the hop-up. In gas blowback pistols, to adjust the hop-up you often need to take the whole upper receiver off, and then turn a small wheel near where the bb is loaded into the inner barrel. If it is not in one of those places, check the instruction manual. Usually, turning the hop up clockwise will make the bb fly up more, and counter clock wise will make it fly up less.
you don't. uhc super 9 don't have it and the uhc super 9 pro have fixed non-adjustable hop up.
UTG M324 is a great buy and it is about $120. It has great hop up, it is compact, and it is relativity silent and accurate.
Because of strong muscles in their back legs.
To be a good airsoft sniper, you need to have a decently good sniper in the first place. Second, you need to zero in your scope and hop-up to make sure its dead on. Third, I recomend buying a gillhee suit, to keep you camoflouged. Lastly, if you cant get a gillhee suit, play your matches in the forests, where you can cover yourself in leaves.
it is like a hop up system but you can change the bb's left and right trajectory ans well as the up and down trajectory. It also has two contact points shaped like a V so that the shots will not go crazy, each shot will be the exact same as the last (unless you adjust the hop up)
It has eyes that provide excellent vision for the nightIt can hop well for climbing in the mountains and can hear well.
