I'm doin research before I buy my first gun, and I'm looking for a little more information on the CA M15A4. I've watched a few review's on youtube, but I'd like some information from people who've used it in my own country, maybe even some pictures. If you've used/owned this gun and were displeased, please tell me what problems caused this and maybe suggest another gun/brand that I should look into. Thanks for any effort

Also, is there any differences between the carbine and the long in terms of performance?
