Be very careful of youtube reviews a lot of them are sponsored so will praise even the biggest piece of crap on the market.
A lot of the others are "look at my new gat its the bestest ever and I know this because I own it and paid for it out my own pocket money bro" sort of thing.
Trust the forum advice over youtube, just dont listen to sittingduck because he will tell you to buy a G&G combat masheep but they are made out of cheese alloy.
