it lasted this long with no spares right?
besides.. you gonna have a gunsmith headspace it afterwards?
as for cleaning fluids.. I'd keep some spray cleaner like brakekleen, some silicone spray.. and some synthetic oil. walmart sells quarts of 10w30 and 5w30 synthetic engine oil for like 5$. a quart will lube yer guns in the hereafter past your lifetime
I use that syn oil saved from 'empty' bottles.. use it to lube my relaod equipment. works great and is 'free'
after a couple oil changes.. I had 4-5oz reclaimed.
some syn grease would be nice too.. remember.. a lil lube goes a long way on a gun.. and more is not better.
ps.. that's just what i'd do.
I'm no expert by any means.. just ask LD..
