I've had about 3-4 transactions with Rainman. And had several custom pieces made, guns milled, and annodized. His work is top notch and so is his quality and attention to detail. I recommend him to anyone looking to customize their gear.
I bought a cocker grip frame from rainman awhile ago, He shipped EXTREMELY fast and was very friendly and helpful with my problem aswell as selling me a great frame! RM is the bomb and I look forward to future transactions with him!
