Just gave the old girl a service

Decided it’s been a while since I got old Bertha out the cabinet… So gave her a service and re greased her then ran through the chrono to see how she’s running…it’s still good https://youtu.be/_RiYLSkrtBk

How does it go for accuracy man? I had my M4 clocked over 360fps, I’ve just been working on tuning it down. I’m at 290 now and accuracy is way better but I still think it should come down to about 270 for the absolute perfect tune.

Overall accuracy is pretty good at 20m in burst fire you get 2/3 straight and that last one mite veer off But in terms of hitting a Target it’s good. Only issue I’m having it getting the mag to sit still. As the vibration makes it drop a little after couple shots
