Things I liked:i liked the metal clips,the durability,the camo,and the tactical bipod.also 85 percent of the gun is metal, and you get used to the weight. the gun is very powerful and does a wooping 485 fps. Things I would have changed:i would change the reloading but i am not 100 percent how to use the speed loader it comes with but its no big deal. I also would suggest getting a new sling cause it isn't the best sling but its not very expensive to buy a new one. all the other things you need to buy is a new sling if you wnat one and a scope if you want one. What others should know:this gun is sweet for wars and hurts if you get shot by it. TRUST ME!!!!! if you want more velocity than accuracy use .12 gram bbs or lower if possible.if you want accuracy use .20 gram or higher. if you are more of a stationary sniper this gun is made for you.if you like to run with a sniper i suggest using A sling for it.
