Took a little polish - TacFire .45 ACP Complete Upper Assembly

This upper took a little work but works as it should. The round would only chamber about half way. Machining did not look smooth or finished. Removed the bolt carrier and and chucked up a 12" piece of 3/8 dowel with a vertical cut to hold a piece of 600 grit wet/dry sand paper and a little oil. Took about 7-8 seconds with the drill on high to hone out the chamber. Unit cycles perfectly now. However the compensator that comes with it really dirties up the barrel and blows fouling back into the action. It works well but will order another brake. Over all I'm happy with it, just wish TacFire would polish their process.
