I am new to airsofting and i've decided i dont want to spend a lot of money on my first AEG. I've been looking at the Cyma mp5k pdw and the CM041 MK5A5 RIS. I am very small and have short arms so im not sure if the MK5A5 will be to big or not. I also like how its costomizable unlike the MP5K. If anyone can provide some help as to which gun to get or if you have any tips for a beginner airsofter please post.
