Thanks guys!
I wasn't really thinking of tracking one down, I was more thinking more along the lines of what HeartBlade said "good replicas of the booster do not include the bearing so it is additional proof that your bearing is real." And though I did read a post in a gun forum where someone mentioned Roman's replicas as a possible replacement in lieu of an original booster, they weren't quite sure of doing so for live fire. Noone in that thread mentioned anyone in the gun community creating replicas, and I felt more at ease about the possibilty of there being fake boosters out there once I read what HeartBlade said. Then of course I read the next post and Chris is like, oh yeah I have some replicas, and that feeling of ease lept right back out of my mind. I guess I'm making myself a little paranoid. I tend to overthink big decisions. But once I have all the facts, and make up my mind to purchase something, I seldom regret my decision.
