I need a pinned and welded muzzle device removed, NSR swapped to MCMR, and then a new muzzle device permanently attached. Looks like ADCO will cost about $175 for the work which seems like a fair price, but I used them once in the past and was surprised at how many tool marks were on the upper. Doesn't affect function, got it, but if an upper doesn't come like that from the factory, I don't see why they can't do it without scratching it up. Rainier is the only other shop service I've used and they did good work, but it looks like it would cost an extra $100 for their labor because that includes hand fitting and headspacing, which I think is kind of bullshit on an AR. Any recommendations? Its already boxed and ready to go, I'd like to send it off tomorrow before I sit on it any longer.
