on my olympic arms today, it's been officially de banned. 4 position collapseable. Man it's so nice to see this gun configured the way it's suposed to be. After the class, I'll be having the barrel de-banned and a phantom will be replacing the y-comp. I can;t wait. On monday i'm going to go meet up with a budy and were going to switch out my A1 upper for a flatop, and put a YHM lightweight railed forend on the Hbar. Oh I can't wait to get this all done!!!!. Still waiting on the sling and a couple scope mounts. once all thats in I'll be set up and ready to roll!!!
