I sent my trigger in last year for a Tier 1 job, figuring I'd support a local company rather than give my money to Volquartsen or Kidd. It really wasn't much of a gamble, Brimstone has an excellent reputation. More than my aftermarket stock, bull barrel, or Leupold scope, the Brimstone trigger is by far my favorite modification, and the first thing I'd do to a stock 10/22.
David does a good job. I've had him to a trigger jobon my 10/22 and glock 19. Sights installed on my shield 9mm and my ruger sr9c. He's also threaded and installed a brake on my savage model 12 lrp. All for a reasonable price and turn around time. He answered all my questions and is very easy to talk to.
