Quick little update here, I went to Paul to have my engraving done and holy hell was that an experience. First off, his laser engraving is great. Second, he makes suppressors, brakes, flashhiders, ammo, thread protectors, threading barrels....pretty much anything you can think of he can do. I now have a list of stuff I plan on working with him to get done soon, first off some barrels threaded. I think I ended up spending an hour in his shop getting a tour and his people talking to me in each section about the stuff they were working on.
It's $60 for the first engraving, $50 every time afterwards since he has your info saved into his system. He does is right where you can watch the whole thing. If you get something done, ask him to rub some hydraulic fluid on the engraving as it re-blackens it roughly 90%, I mentioned getting that area re-blackened at some point and he wandered out and back in with some on his finger and took care of it right there.
All in all, it was an awesome experience as I never thought I would see suppressors, brakes, barrels, and other stuff being built in person like I did today.
