So Ive been testing this. It is VERY good. I think that you should maybe add ironsights to it. Also, I thin you should add to the range of the bullet, and/or make the bullets be effected by gravity. Its odd when you shoot at something that isn't TOO too far away, and you don't see any projectile/ bullet hit. Thats just my opinion. Everyone, including me, LOVED this gun!
I encourage you to make more of these and eventually release them :)
