    Group it, then decide. I have barrels ten times uglier under a scope to include a really ugly leade that still shoot MOA.

    I have an FN Optimum barrel on my favorite build.

    Glad it was just jacket fouling. Cool scope.

    Teslong? I think is the name. It's not expensive; the trick is adjusting the head/lens. I've got it at the sweet spot for .224 bore


    However, let this thread be a warning, most guys freak out/overreact/misinterpret things they see in the bore scope. I'm guilty of this myself...one time I thought my chrome lining was pitting...it was just carbon fouling. The pic in question:

    I've posted on here before that I've scoped FN, Hodge, DD, HK and Bartlein barrels and how fresh/clean the rifling looks is not necessarily an indicator of how the barrel will shoot. That FN above with those striations across the lands and groves is a decent performer compared to some things that look like glass but just phone it in at 2MOA.

    It may be the best/worst $75 you ever spend

    Thanks. And i have seen some threads on TOS with people freaking out. I know some not so great looking barrels can shoot well and shooting it is the best way to see what a barrel can do. I would just like on to have in case i need it. IE if a barrel is shooting bad from the start it may help further diagnose why

    I use my Teslong to compare gas port erosion given the documented number of rounds fired. Mostly useless but interesting to compare to used uppers I have bought.

    Funny enough a lot of those "defects" like rough spots gets ironed out and "chips" get filled in by jacket material when you just shoot the damn barrel.

    Glad to see it's gtg. Though I rarely use my Teslong I do find it be of a very acceptable quality. Especially for the price.

    Perhaps I overlooked it. Which copper remover failed to remove the residue?
