10gauge,
I've bought several items from them (10-22 & Ruger Mark Pistol stuff=> including VQ and Tactical Solutions' Ruger MK 3 & 4 uppers, and VQ trigger kits for same).
I think it is a one man show.
No complaints.
I bounce around from them to grabagun, brownell's, and Midway for availability and best price. Grabagun had(has?) the best price on 10-22 & Mark 4 magazines. Brownell's seldom has good prices, but if I'm unsure about an item's fit or utility I buy from them as they will take it back with zero issues. Midway has some good sales and I use their reviews.
