I found a M4x30mm screw cut the head and 10mm off it then cut a flat head notch in it so its a flat head 20mm grub screw
Screwed it in till flush and was getting lots of 795`s over the chrono but a few drops to 780 not great but 15fps spikes are better then 30-40 spikes.
Hope get to do some proper chrono-ing at the club soon as the AR20 is to loud to be shooting so much in a terrace house.

The AR20 has a fairly unique set up whats the optimal FPS?
