so im looking to upgrade the internals on my 10/22, but im on a college student budget. the biggest thing im looking to have answered is what order i should buy parts in, and what parts i should get. on midwayusa.com, they have a volquartsen action parts kit plus which includes: target hammer with shims EDM disconnector EDM sear target trigger with overtravel adjustment trigger plunger with an improved radius trigger plunger spring special hammer spring recoil buffer to reduce wear on the action and bolt. all of this for only $137.99. now, i went through volguartsen's parts list and this is what i think i wolud buy if i got parts seperately: target hammer target trigger extended magazine release auto-bolt release all of these great parts for a whopping ~$90 now, is it really worth the extra $50 or so dollars for the extras that the kit gives you? their description says it gives a "crisp clean trigger pull" which is something i'd like. however, if there isnt much of a noticable difference from the stock trigger its not important. lastly, is there a certain order i should buy parts in that would be the most economic?
