Smoother, More Durable Main-Spring
1873 Style Rifles - manufactured by Uberti
Want a Faster Lock Time?
Tired of those intermittent misfires?
Tired of continually adjusting hammer tension?
This is the System!!
TK4B Enterprises, makers
has produced a newly designed “SliXpring-Main”
replacement Mainspring system that is designed to complement an already
properly tuned and short stroked Winchester style 1873 rifle or carbine.
Its sole purpose is to provide a faster lock time (faster, more
positive hammer travel), a more dependable primer strike and a more
durable, longer lasting, smoother cycling competition grade spring
operation. It, in most
cases, will feel a bit more brisk in the initial cocking action of your
rifle, but be assured it will respond much more smoothly throughout the
hammer cycle than a normal leaf style spring, plus it is at least 30%
faster than your competitively adjusted leaf spring.
kit requires competent installation with minimal stock fitting and is
completely reversible to your existing arrangement.
Because there are so many different tolerances and
dimensions between bolts, hammers, lower tangs, action frames and
tune-up styles the “Kit” itself is manufactured so the qualified
installer/tuner can fairly easily fit and align the unit for optimum
operation with minimal alteration. It will not
fit the earlier square bridge lower tangs and some Border Rifle tangs
without Tang modification. Also, since there are many different styles
of shooting and needs for different levels of speed, the kit will
include two axles. The
basic axle will provide the fastest possible lock time and the most
positive primer detonation while still retaining a smooth action cycle.
A smaller diameter axle is also included which will still provide
a noticeably faster lock time but with a slightly lighter, smoother
lever cycle feel for the not yet absolutely competitive shooter.
The manufacturers want to clearly point out that if
you have little or no idea how this Spring Kit is supposed to work, get
help or find someone who does know how to install them.
Due to all the variations in machining tolerances on the
different rifles this is
a “one-size-fits-all” perfect “drop-in” set. It may/will
take some individual fitting.
Contact your local “Smith” to arrange installation.
Our practice installations have taken about an hour to finish.
