What I am currently using are Bartlein barrels, not "breitling," and Shilin as well and God help your ass when you don't know what Lilja is and don't spell it right as Danny is going to kick your ass. Accuracy is important, even in spelling, as to finding what you want.
I may be wrong, but I feel that you are a young person trying to get into shooting, and I admire you for that and hope you stick around, but, you haven't a clue as to what you have, nor how to best to use what you have on hand, nor how to use it as is. Maybe 20 rounds downrange? with that rifle.
Were YOU to drill and tap the reciever and mount a scope, and not a GOOD Gunsmith, would your bolt lift and clear the scope that you just mounted without you doing anything to that bolt? Maybe it would have been best to just leave it alone and shoot iron sights.
I will help you all that I can, but I suffer no fools. It took me a while to learn that from others, but I did. FM
OR, Are you a TROLL?
