lazy screw bren gun or rifle?

As a boy soldier, our weapons instructior, told us where the lazy screw was situated,i remember where its situated,but dont remember whether it was the 303 rifle or the bren gun?anyone know?

 

Theres not many screws on a Bren, apart from the butt there are 2 on the Bren (That I can think of) so I suspect it must be the Enfield rifle. Can you remember why it was called the Lazy Screw? Is it because the screw dosn't appear to do anything?

 

Memory - 1964 cadets recruits test - No 4 rifle name all the parts (still can) the extractor on the face of the bolt extracts the cartridge as the bolt is pulled back the rim hits a projection (if it has not already ejected by the return speed of the bolt) which is the ejector screw. Could it be this?

The Home Guard Manual 1941 (the reprint) lists the 'lazy screw' as part of the backsight. The accompanying drawing just says 'screw'. Inevitably, the section on aiming makes no mention of its purpose. Stuff I've seen so far says the sight had a wind gauge and fine adjustment for elevation, so it could be either!

10a is the Windgauge, 10b is the Windgauge Screw. As above, the instruction is to aim off for the effects of wind rather than using the windgauge - perhaps it's a lazy screw because it's never used.

 

guess idler you came the closest, the lazy screw is situated in The BED of the back back sight,this was told to me, by my platoon sergeant.A sergeant Suddle of The Royal Norfolks,way back in 1955/56,and it stuck with me ever since,could be because I sleep a lot. LOL now I know it was the rifle Thanks guys for your help,

 

I never heard that term for the screw that retains the backsight spring. I guess it was just an individual joke by the SNCO?

p.s. why would he be referring to the No1 rifle in 1955, when by that date even an SNCO would probably only have encountered the No4 during his service (ie 13 years since the No1 was replaced for UK regulars).

all I know is I was a boy soldier in the Infantry boy's Battalion in Plymouth and that was how it was explained to me,maybe it was a joke the way he was explaining it,if it was, it worked for me,for its stuck with me for about for the past 56 yearsps our weapons instructors came from the School Of Small Arms Corp.maybe it was an instructor who explained it that way and not my platoon Sgt as I had stated,

 

I was under the impression it was the 'screw' that goes horizontally across the rear sight of a No.4. It appears to be a screw but, in fact isn't. It has a screw head, but no thread (instead it is a cross-bolt held in place by a pin on the majority I have seen), which means that while a screwdriver can be used, the 'screw' does nothing but rotate. Later versions did have a small amount of thread but a similar situation ocurred - not all receivers hd a receprocal thread. Mine certainly don't.
