The parts from Kidd are as the highest quality in machining and materials and DLASK is very comparable. I have a bunch of custom 10-22 variants in both 17 mach2 and 22. The Kidd or DLASK bolt will improve reliability as well as accuracy. They have much better extractors as well as pinned firing pins which are not stamped but wire edm produced. They are also radiused where needed and highly polished. Check to make sure your extractor and the extractor groove in ur barrel are clean . They should also be in alignment and not rubbing on one side or the other but extractor in the middle of extractor groove. As far as triggers I have experience with a bunch and will list in order what I think from best to worst. Kidd,Timney,Volquartsen,and Bx. The Kidd is as good as a match trigger on a centerfire rifle. Expensive but impressive
