I am currently looking for an m4. I am not super rich, so my budget is about $230. I was looking for a good quality gun that was pretty accurate stock, because I probably won't be upgrading anything too soon. I am leaning towards the GR15 raider, but at $210 I would need a crane stock battery, so that might be more than my budget. I was also looking at the Classic Army Sportline, which I am unsure about but have heard good things about. Also, I was looking at the Smith and Wesson MP15 that ICS has, since I really like the split gearbox design. So could you guys please help me out? Any help from people who have owned these weapons would be great.Thanks in advance for all who help.
