Woodchopper the front sight is still original, however the bayonet lug is cut off and the barrel re crowned. I was thinking of just putting the nice forestock on along with the uppers etc and installing all the other bits such as the front sight ears. Would that not look good?
well you have options.
it will always look funny with the full wood and bobbed barrel.
one option would be to find a parts gun with bent barrel or buggered receiver that still has the bayonet lugs, ad cut off the last few inches of barrel bore it out to about .375 (3/8") and then use that to sleeve over the end of the barrel as near as you can to the bayonet lugs and try to hide the splice with the front sight ears.
you would have to turn down your barrel and cut a step in the sleeve bigger then 3/8", I don't have a barrel to measure but 5/8" might work ok.
this way you would have a barrel that looks correct with the full length forestock.
when guys say tanker it usually implies an 18"- 22" barrel chop, modified wood and other parts, like what I did.
Go the opposite way and cut the barrel shorter. Beater has made a few as well from sporters but I don't think he does the spliced foreends like I did.
your choices will depend on your skills and access to a lathe.
Now if you just put that forestock and wood on the bobbed barrel, it will always be an obvious bubba with a bobbed barrel. I would buy it cheap take the wood off to restock one of the ones with a full length barrel I have kicking around in my pile, throw some sporter wood on the supporter barrel, strip off the best and interesting parts and replace them with some less desirable parts from my bins and just sell it again.
to me its not worth the effort and there are other sporters out there that are more interesting and are not cut, like the early 5C savage Mk 1 no star I have with most of the original parts like the button style cocking piece that are worth restocking. But that one needs a low wall Mk1 forestock and those are not that common.
One thing I don't see in you questions is if that is a Mk1 or Mk1* rifle and if the stock has the cutout for the bolt release of the Mk1 or not.
