Enfield Rest Telescopic Sight Layer with storage case--Canadian Long Branch

[Peter Laidler]

The explanation isn't QUITE correct Paul........ We had these layers, one issued on the AinU account with each Enfield Rest. The system was to boresight the boltless rifle (we used a slave bolt body with a reduced bolt bore diameter) then used the layer across the backsight and slipped over the foresight blade. A quick glance through the layer at the target would show how far you were off the PoA. Those that were good or who did it regularly (range testing at Base Workshops was always a bit of a chore, believe me, especially in enclosed NDA ranges) could tell you pretty well exactly where the MPI would be.

As a result of that info you could change the foresight, left/right/up/down, put it back and you'd be on target. Test fire a 7 round group, tweak if necessary and that's be it. It made it VERY quick.

There was also an adaption for the L1A1 too but this was slightly different because the vertical adjustment was done on the foresight and laterally, by the backsight so the formula for the backsight adjustment was reversed for optical reasons that I won't go into. The same layer was also used for the No5 and if you look under the underplane, you'll find another thin slot for the shorter sight radius of the No5 rifle

We used to do the No4 snipers with this and also the tele sight. That's why the No4T and L42 paperwork always went back to the unit/sniper endorsed with 'SNIPER RIFLE Noxxxxxxx. FINAL ZEROING IS THE RESPONSIBILITY OF THE END USER.

Hope that's cleared things up a bit unless you already knew this
