Just wanted to scope it to see if I'm cleaning it okay, didn't expect to find anything. I don't know if this happened on the last round or the first round but the gun did shoot sub moa using non-match factory ammo so I'm assuming its okay. I bought some match ammo, and made some hand loads so I should know how well it shootsIf it shoots, shoot it. I don't scope barrels, because they either shoot or they don't. I've seen these videos and pictures where the barrels look like they were the remnants of a bad car accident, but the owner claimed that they shot .5moa.
It makes no difference what it looks like, only how it shoots.
