I am new to GSSF and will compete for the first time in the Amateur Civilian Cataglory this comming September. I want to pracice a bit for the competition. In doing so I want to make sure that my gun will be set up the way it needs to be for the competition. After reading the rules, I find them somewhat unclear (probably b/c I am using a loose interpretation of the word "stock"). Well my question is it legal to have non-stock sights(I have meps) and a 3.5# connector made by glock?
