Ok i figured it was something i did, will this increase creep?
No, this screw merely prevents any further movement of the trigger after the sear drops. It is a screw that is usually mis-adjusted by well intentioned folks. Properly set, you should just feel a slight amount of play in the trigger after the sear has dropped. This little amount of play maintains the proper clearance so the gun will still cock and function when parts heat and expand. It doesn't affect accuracy.
