Things I liked:Before I start the review, I would like to say that there is NOTHING bad about this gun and nothing has broken or went wrong since I had gotten this last year. The UTG Master Sniper is the only sniper I would recommend to friends and players because it is very reliable, accurate, strong, and comfortable. I've been seeing reviews about how it needs a cheek rest and I have to say it doesn't need one at all since it is very comfortable when standing up or laying down. There is nothing to not like about this gun. Things I would have changed:There's almost nothing that needs to be changed. But when I had gotten this gun, the scope that came with this gun (Swiss Arms 4x40 scope) was inaccurate, heavy, and not very reliable. I'm not sure if I should give it 4 stars for that because that problem was my fault for getting the gun with that scope. Because of that scope being so heavy, it caused the top rail to become loose and the rail needs to be more secure when there is a large scope mounted. Other than that, this sniper is perfect. What others should know:If you plan to get this sniper, there are 3 things you should know. First is that if you can't decide what BBs to use, get .28 5.92mm BBs or .23 5.95mm BBs. Air Venturi BBs are very good and I recommend you get them. I haven't used any other BBs in the gun and those size BBs seem to work extremely well. Second, do not buy this with the Swiss Arms scope and get a lighter, higher quality scope. If you're low on budget, get it with the Swiss Arms 4x40 scope but be careful with the scope and the top rail. Lastly, I can't say the bipod is good but I can't say its bad either. If you have the money, might as well get a new bipod. If you don't have the money, it will work fine.
