Moderator: I was uncertain whether to place this query in GUNSMITHING or in MILITARY RIFLES. If you believe it is wrongly placed, please move it.
**************
During World War II Great Britain, Canada, and the United States manufactured variations of the SMLE No. 4 rifle. And Holland & Holland rendered a small number of No.4 Mk. Is into sniping/target rifles for extreme long-range accuracy.
1. No. 4 Mk. Is have a spring-loaded vertical interlock that need be used to allow its bolt head (and bolt) to be removed from the receiver while No.4 Mk. I*s use a simplified system that dispenses with the interlock assembly in favor of a rotating bolt head-with-slot. I am nearly certain that No.4 Mk. I*s are unable to use No.4 Mk. I bolt heads because the slot that allows bolt insertion and removal is absent. . . . BUT can No.4 Mk. Is accept and function correctly with No.4 Mk. I* bolt heads? Is the presence of its slot irrelevant for use in a receiver that allows bolt head to be manipulated by way of an interlock?
2. Holland & Holland created a small number of long-range No.4 Mk. I rifles. Did these rifles use [especially adjusted] military trigger assemblies, or did Holland & Holland use some sort of target/competition trigger that was designed to be adjustable? If the trigger was a military assembly, what was the result of 'smithing it - that is, weight of pull, creep, did it retain the "double-pull" feature, etc.? I've always believed that while standard military double-pull triggers can be "improved" by a gunsmith to become acceptable for most big game hunting, for precision a 500-800 yards, such improvement by gunsmith just wasn't possible.
3. Following up #2, since SMLEs as competition rifles have been in use for generations, it is likely that third-party match triggers have been made. Please identify adjustable target/competition trigger assemblies, also such trigger assemblies that can be installed on No.4 Mk. IIs.
4. Many years ago I read an article that described a simple, easy, inexpensive method to alter No.4 elevation-ONLY rear sight assemblies to allow some windage adjustment also. Of course I no longer have the article, nor do I remember the process described. I will appreciate information pertaining to how to render the sight assembly adjustable for windage and elevation.
5. Following up #4, please identify adjustable target/competition rear sight assemblies, preferably that are close to as compact and sturdy as the military assembly.
