AT THIS TIME) We are currently producing a DIY Discovery/Maximus
Tune video... Should be up and available by January 14th, 2017.
feel that we offer the best Discovery Air Rifle tune in the hobby
$80 Discovery tune includes:
the gun for accuracy and shot string before disassembly
and check for wear and corrosion
barrel, smooth leade (chamber), chamfer the barrel inlet port
and lightly lap the first 2/3 of the barrel. We also slug the
finished barrel for tight areas.
.001 from the breech end of the barrel.
the airtube slots and screw holes
the striker bearing surface
the striker, especially the nose section
work depending on the level of power wanted (We aim for accuracy
first, then work on power if wanted. We feel that an accurate
gun (and one that gets more shots is better than a powerful gun
that won't shoot straight.)
assemble the ports with a polymer glue to create a perfect seal
from the valve to the barrel
and tune a TKO Drilled Barrel band
work includes adding a sear engageent adjustment, polish the sear
and transfer link, changing the trigger retur spring and altering
the sear return spring.
assemble the finished action in our test stock and shoot for accuracy
and shot string
Tune is guaranteed to exceed the factory accuracy level of the Discovery.
BSA Lonestar tunes $80:
The BSA Lonestar is a trememdous value for the money with a terrific
barrel in all calibers. It has the potential for great power with
a rather easy to perform tune. We remove the valve choker and enlarge
the ports slightly which can build tremendous power... but at the
e xpense of shot count with the rather small airtube.
The BSA is a bit tricky to disassemble and assemble correctly,
and the trigger parts benefit greatly from a re-hardening and tune.
assemble and test 3-4 of the Crosman based PCP pistols each month.
Each gun has a unique set of features, but all are built and tested
for accuacy above all else. Even though they look huge, they handle
and shoot beautifully. Models include specific features for field
target, hunting, plinking, high shot count, or power. All have great
triggers, either tuned Crosman trigger parts or TKO 2-stage trigger
assemblies and either a TKO Stage V brake or the TKO MB-50 target
