Kjw m4
 

Hey guys i have a kjw m4 v1 and years ago i did the cradle airsoft bolt upgrade and tdc hop up upgrade. After about 8 years of use my cradle airsoft bolt snapped in half. Lol so now im back to the v1 bolt with the cradle airsoft nozzle and velocity reducer. My question is; how is the v3 bolt? I had the v2 and it was crap but im wondering how the v3 is and if its superior to the v1? Any feedback on this would be great.
