Nice gun. I like the look of it with the silencer, flashlight and laser.
Just be aware that full auto pistols tend to be a real pain in the ass and extremely high maintenance. They tend to break down a lot. It's going to be expensive in parts and labour to keep it running if you use your pistol in any any appreciable manner. And also, the laser is nice, but you won't be allowed to use it at games because of potential for eye damage.
