I headed out yesterday to do a little zeroing in with my ASR, and was not exited about the accuracy I got. First up, here is a list of parts/ modifications I have done:
Echo 1 Upgrade Kit
Mad-bull Version 2 509mm 6.03 barrel
PDI 96 hop up
Guarder bucking with dental floss insuring tight fit
Six barrel spacers
Polished and slightly widened cylinder head as per here: http://www.airsoftforum.com/board/Upgraded-Cylinder-Head-t87014.html
Teflon taped cylinder head, and piston head screw
I shot from 100 feet using .25's at a torso sized target, and while I could hit the target every time, there where no good groups to speak of. I then moved the target out to 240 feet, and had no consistency at all, any hits were pure luck.Also, while the time it took the BB to hit the target at 100 feet was roughly one second, the time at 240 was incredibly long. I had time to lift my head from the scope, and count to 3 before hearing the hit. Seems like the fps are slowing down a lot, but my gun is shooting hot (550fps).
I'm getting .3's and .4's soon, I'm assuming this will help?Any suggestions/comment would be appreciated!
