i received a PM from a member of this board and he has thrown a doubt as to whether any russian SKS are chromed bore .

i visually inspected mine and bcos i dont plan to shoot them , i was unable to positively say yea or nay .

from all my research (books , sites and gun boards) indicates that there are chrome bore in russian SKS but is there positive method to testing the bore myself?

Did a little search on google and this is the only test i could find...A drop of cold blue will stain the bore if the barrel is not chrome-lined. It won't touch the color of a chrome-lined bore.
 
My '52 refurb sure looks chromed.I have a Chinese chromed I will have to compare it to.I heard that they put on a chromed barrel when they Refurb it if the barrel looks rusty and grey, and leave it alone if it dosen't look too bad.That is why some members were getting dirty dark bored refurbs and others looks shiny, because it is a new barrel.I would rather have chromed, even if it doesn't shoot as good as a non chromed barrel.I think if you have a shiny ring, on the crown of the barrel, it is most likely chromed.
 
results are in

yes, deanner is correct , this method does work .

firstly , i use the instant gun blue on a piece of steel and on an spare chrome faucet , cleaned the surface with varsol , i used a q-tip and dab gun blue on the steel and instantly it turned black and then i did it to the faucet and nothing happen , the bluing solution just sat there till i wiped it off and still no sign of any reaction to the bluing .

secondly , i used 3 rifles in this test .
1. a known chrome bore , an early chinese SKS , factory 26 1965 , althought there is no sign of the chrome by looking at the crown (this was the same with my other russians) so visual is not always reliable.

2. a known non-chrome , a russian 1950 , refurb , paint on the crown , i steelwool off the paint, dull color steel underneath .

3. a known chrome , a russian 1954 , refurb , paint on crown , when i steelwool the crown, this one i can see a chrome near the muzzle .

thirdly, i applied a dab of bluing to the crown and also to the chamber of each of the SKS and these are the results .
1. factory 26 1965 , crown did not change color (indicating present of chrome) but the chamber did (absent of chrome) .

2. russian 1950 , crown changed color so no need to do the chamber.

3. russian 1954 , crown did not change color but the chamber did .

conclusion: the russian SKS bore has both chrome and non-chrome , and the chambers are all non-chrome.
