  1. Greg S.

    Purchased MBA-1 (elsewhere) to serve as a fixed stock on an Indian Creek Tommy chassis. When installed on a std. mil-spec buffer tube, the chassis isn’t long enough from the back of the mounted pistol grip to where the tube inserts. With the MBA-1 installed on the tube, the lower front portion of the stock prevents getting your hand between the grip and the stock. Maybe the design works with other fixed stocks but not the MBA-1. Returned the stock and will get an MBA-3 and an adjustable buffer. MBA-3 doesn’t have the protruding lower, forward portion like the MBA-1. Both the chassis and the buttstock are nice pieces, they just don’t go together. Thought you guys should know…
