Quality also means that even although everything looks nice coming across the parts counter when new, what materials are used will tell you how long your hard earned money is going to keep in the real world of use. Constructed using polished stainless steel endcaps, a stainless steel interior tube and a clean sleeve with no rivets to rattle loose or wreck the sleeve, as many of our competitors set-ups do. Micron canisters use our newest 3&4 bolt end cap designs, which means that unlike companies which are stuck in the 1970's and still use rivets, our canisters have NO rivets holding the sleeves to the canister.
