May purchase an upper from them, asked if they would shave down the FSB so I didn't have to duck with it.......do they do good work, yea I know it's just chopping down a FSB but we all know how even the small things can get mucked up........they any good?

They sell a lot of stuff and I haven't seen much at all negative about them.

FWIW, I ordered two barrels both priced at about $550 each from ratworx a few years ago, Both barrels were wrapped in butcher paper and put in a triangular USPS shipping tube. The package arrived with the muzzle end of both barrels sticking out of the box. All that held the box together on the end was one strip of packing tape. Luckily the barrels had a flash hider from the factory installed.

I hope that person who shipped my order no longer works at ratworx.
