Well ive got a ULE RT Pro custom and ive been trying to get it to run right before my first game with it. First it was having bad bolt stick every 15 shots, used the level x tuning guide and lubed it well and everything seems to be running ok now(still gotta crono it and see where I am but thats life). Then I decided to mess with the ULT a bit to get some reactivity out of it. Im using a crossfire tank and added 2 shims making the total 4 shims. I get some reactivity but not runnaway which is what I want(allows me to do 3 round bursts nice and easy). My current problem is when I added the shims it now makes a weird squeaking noise every few shots? I placed like 5 drops of oil in the bottom line and fired around 30 shots through it, doesnt seem to have helped. What am I missing?
Thanks
Thanks
