[john walker's workshop]

geeze, just get some stock, normal sized guides and install them in the stock, normal bores. i do it all the time and there is no fitting issue. always important to use a micrometer and compare the old and new size so you don't split the guide bore. new ones tend to be a couple of hundredths of a mm oversize anyway, which is a good thing. 1st over is way too big.
