Finally got a hold of Para. At least when they answer they are willing to talk for extended periods to resolve your questions. Regarding the barrel they say to wait till the 500rnd break in period is done than see if im still having issues. My trigger that has alot of side to side movement in it is another story. they will look at it provided i send it in to them sometime soon. I will once i get through the break in process. I also asked them about night sights and they gave me a website that makes them for a GI style rear sight. i will post that link below. They also answered my question on my recoil spring. The standard spring in Para Experts is 18lbs. So at least now i know that. So i got my information now to see what i can do bout making the changes i need. Thanks for the advice guys.
