Well mine is pretty bad ass and it came shooting 385 stock! no joke. But i guess u can have your opinion.
You are basing whether or not you got a good rifle on FPS? Fail.... if its shooting that high stock, and you had nothing done to it, then its probably an Echo 1, in which case, good choice. CA G36's are about 340- 350 stock, FIRM. So unless you had it modded, or got it second hand, I think you need to get it re- chrono'd. But whatthefuck would i know? I gave you my best assumption of what was wrong based on a lame one line explanation, so try and fix it if you can, im not going to sit here and argue this.
