what to carry

[Tartar Horde]

Nothing lasts forever, no matter how many spare parts you have for it.
That useless expensive club may very well come in handy - there's not much that can go wrong with a scope - as long as the glass isn't broken.
Open sights are usually just a reference point anyway, same with a scope if you're firing at a different range to what it's zero'd in at.

I have had three scopes that have broken the reticules BM due to recoil, trust me mate they do break, but you're right the lens tend to be tough. I am unable to make any parts for a rifle in a SHTF scenario, and to be honest don't know many people who could, they all rely on put by spare parts. The only weapon I myself can be truly self sufficient in is the Bow as I can make everything I need to shoot, the only other weapons I could honestly put my hand on my heart and say I could make would be the Atlatl and spear. I could make a catapult, or even a slingshot rifle but eventually the rubber would run out and there aren't many rubber trees in East Yorkshire. I may be taking an extreme outlook here but I don't like relying on something that relies on other people making parts for it.
