Thread: trouble with Superlative Arms Adjustable Gas Block

OK so question im using a promag 5 shot and i'm starting to wonder if its not coming up and holding the bolt back but some times it is.... hence i feel like i'm running around in circles, ive had it hold the bolt back at 18 clicks out(max gas pressure) also at 27 also down to 14 but ive also had the opposite and its getting really frustrating as to what the thing actually wants... as i think the mag is giving me dramas ? pretty sure i'm not doing it wrong seems pretty simple, is there something else it could be ? seriously think its the mag....? i did see small amount of powder residue coming out the gas tube rear of the gas block too?
