When I first bought my 1894 I read alot about the gun . I've noticed alot of enthusiasts not only dig the pre 64 because of the nostalgia factor but alleged changes in production quality . From everything I've learned about those changes I have come to the conclusion ( now this is my humble opinion so feel free to disagree ) pre 64 version does not stand out to me as a superior rifle. Let me explain Pre 64 1894s had a solid steel receiver , solid steel roll pins and a solid steel cartrige elevator . And was a top eject rifle . 1964-1977 Errr dunno much cept they used more solid steel than post 1982 1982 -1992 1894s have whats called a sintered steel receiver ( http://en.wikipedia.org/wiki/Sintering ) which from everything I could find is either equal to or stronger than solid steel . The only disadvantages seem to be 1. sintered steel doesnt hold bluing as well 2. 100% sintered (iron ore) can not be charged in the blast furnace. 3. By sintering one cannot create uniform sizes. Now again feel free to disagree as I am no metallurgist but Bluing on my rifle is immaculate after almost 30 years What does charging in a blast furnace mean ? With any luck my rifle will never see the inside of a blast furnace sooooo I dont think that would mean much pre 64 post 64 argument . And the fit is more than acceptable on my rifle so uniform size ??? moot Advantages are 1. Very high levels of purity and uniformity in starting materials 2. Preservation of purity, due to the simpler subsequent fabrication process (fewer steps) that it makes possible 3. Stabilization of the details of repetitive operations, by control of grain size during the input stages 4. Absence of binding contact between segregated powder particles – or "inclusions" (called stringering) – as often occurs in melting processes 5. No deformation needed to produce directional elongation of grains 6. Capability to produce materials of controlled, uniform porosity. 7. Capability to produce nearly net-shaped objects. 8. Capability to produce materials which cannot be produced by any other technology. 9. Capability to fabricate high-strength material like turbine blades. 10. After sintering the mechanical strength to handling becomes higher. Now theres alot there so I won't go over the specifics but I'd say that list speaks for itself . Only other 2 differences are a stamp steel cartrige elevator ( Does that make a difference? I havnt seen 1 complaint of a elevator deforming or failing in all my research . ) Hollow roll pins ( makes it lighter?? again I havnt been able to find one instance of a hollow pin failing in all my research ) Ohh and lets not forget the angle eject allowing for a scope. Which the advantage is debateable considering the 150-250 max effective range for hunting for this rifle depending on the ammo flat nose vs hornady flex tip im referring to. 1993 - 2006 rifle is now CNC machined , solid roll pins re introduced and made by FN herstal ( good company far as I can tell ) with the only negative being the introduction of saftey sally crossbar safety 1992- 2003 and then tang saftey 2003-2006 Im not going to get into the jap models cause I dont know enough about them all I know is they are expensive and Japanese make good products as far as I know and use good steel but I cant say that is the case in the 1894 cause I just dont know that to be true . So , in conclusion All I see in later models is A lighter stronger gun excluding the roll pins and elevator but again I've never seen anyone complain either of those components failing as far as I could find. And they make the gun lighter So Aside from being a heavier nostalgic rifle you couldnt mount a scope to without tapping the receiver what advantages do the pre 64 rifles have ??? All I ever see is comments like " the pre 64 is a better gun cause it used solid steel components " but from everything I gleaned I couldn't figure out why that made it a better gun . Now I'm simply proposing a question . Again Im no metallurgist nor expert . I very well may be wrong in my conclusions but Id just like someone to specifically tell me why with a more in depth answer than its got solid steel components with no explanation . What say you FTF ?
