Has anyone used the Long Range trigger adjuster? It is listed on page 5 in Brownells #57 catalog.
Basically it is a grip screw with a smaller set crew in the end. The set screw is adjusted to push against the base of the trigger, adjusting the hammer sear engagement.
I have a 50 BMG upper on a Bushmaster lower, and would like to improve the trigger pull. The 50 uses a larger hammer, so the RRA match set won't work. Thanks for any help.
