New replacement Mainspring system for the Winchester 1873Featured, From the Marshal, Industry News Thursday, July 16th, 2009
TK4B Enterprises, makers of “SliXprings*” and “SliXpins”, is coming out with a replacement Mainspring system called “SliXpring-Main” 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.
In most cases, it will feel a bit more brisk in the initial cocking action of your rifle, but it will respond much more smoothly throughout the hammer cycle than a normal leaf style spring. It is at least 30% faster than the competitively adjusted leaf spring. The “SliXpring-Main” kit requires competent installation with minimal stock fitting and is completely reversible to your existing arrangement.
