well im running my sr with an mq2 an a 2liter, with stock settings.
im getting some bad blowback or atleast thats what i think it is.
it sounds normal when im dry firing but then when i fire a ball i get alot of air coming both out the back of the bolt and the feedneck.
im guessing its my settings so i would appreciate it if some other sr owners (preferably if your running an mq) would give me their settings as a starting point to make changing mine easier and also any tips you guys might have.
can't claim to own a SR, but based on what you're describing, it sounds like you need to increase your CDEL setting (not sure what it's called on the SR, but it's the time between sear noid activation and cocking noid activation). might also be the bolt, i think i remember seeing a few threads where people were saying their bolts were way undersized. unload it, pull the barrel, hold the back towards a light and look in the front, and if you see much (or any, since the bolt has orings) light, that may be the problem.
