does the wear from cycle more than compression theory hold tru for all spring's. say a hammer spring, will it wear out faster from shooting as opposed to leaving cocked for long periods. the way i understand either will cause loss of tension over time. if you remove a hammer or mag spring that has been compressed for years it will have lost some tension. i know its apples to oranges but say you load down a truck to rated capisity and leave it sit for a year or two, then unload it. it's not going to be like it never happend. i thought they used cheap springs in usgi because they are considerd disposable. that said crome silicone spring's will out last any other spring several time's over especally in hot envirement's. someone please correct me if i'm wrong, with proven facts.
