This is good Pandan, you should go for making a standard guns pack, like gravity cat tried to do. (Don't add gravity)
For now, my standard guns are just ephi's shotty and kaje's sniper in addition to the default guns. If you keep making your guns balanced with the default guns like ephi's and kaje's are, I think it has the potential to become a useful standard guns pack.
My only suggestion: Make the sniper barrel longer
