50 is the result of a joint effort by two shooting
enthusiasts to make a new lightweight upper with a magazine.
Chaney and Dave Finnie have both been shooters for
many years, and their combined past interests have covered most
forms of shooting, from Black Powder through to competitive Benchrest
rifles, culminating with the challenge of the 50BMG.
has for most of the past decade specialized to the building of
prototype rifles as a hobby and has perfected the art of making
short, lightweight but still very manageable 50BMG rifles.
past rifles are testimony to the fact that this large caliber
does not need to be shot in a massive rifle if the muzzle brake
operation is fast and efficient.
carries out on a small scale basis, the custom manufacture and
repair of mostly Benchrest and other long range rifles, but like
Dennis he also became fascinated by the big 50 caliber.
the past year or so they have shared ideas, and early in 2003
they decided to work together and use their combined experiences
to see if they could come up with a new magazine fed upper for
AR15/ M16 lowers.
Several makers had succeeded with single shot uppers, but there
appeared to be an obstacle preventing a true bolt action repeater.
This challenge was the motivation behind what they now
refer to as the
The basic design was soon formulated, modified and ultimately
the successful prototype was produced by Dennis and Dave
in Dennis's well equiped home workshop in Florida, between April
and May of 2003.
