I run the Chimera MKII basically same as the Spectre just chunkier, anywho i run 16:1 Gears with a Lonex A1 Motor, m120 and a lonex Red Piston
Gun runs awesome, tbh i know tons of people who have been running Spectres and Chimera's for the longest time. Nothing really new here but yes those are great.
and + 1 on low FPS, you should be running at least close to 400 FPS on .2s with an m120 from what i know.
