    Friend of mine just called with a question I couldn't answer short of telling him to go back to our LGS. He bought an RRA meat and potatoes AR, A2 handguards, 4pos stock, integrated front sight, flat top.
    He had a low pro railed block installed and now says its canted about 5deg left. Said his original was as well but never mentioned it because he thought the swap would remedy the issue. It did not.
    Anybody seen this? Is it an installation problem? Barrel problem? I'm stumped.

    Sounds like the problem may not be with the gas block, but with the holes drilled for the taper pins holding the gas block in place. Is the Lo pro gas block pinned in place or is it a clamp on or set screw unit. If it is pinned like the standard gas block, thein it's likely it was improperly drilled and pinned at the factory.

    Most low profiles are set screws. I draw a witness mark with chalk to find the center to line up gas ports. It should take 3 minutes to correct it.
