If you look at it like a normal guy and bought it ($250) then went to a gun smith to fix it?
Shop rate and parts might very well be as High as the firearm aquisition cost.
Then went to fix it yourself, there wouldnt be a shop rate!
Yet the hours of your time searching for the parts needed to fix it could take years (Time is Money)
So your converting $250 of your hard earned Covid-19 era dollars to aquire a non-firing firearm?
So your investing on junk in the shape of a gun that you may find parts for soon or possibly take years to fix?
Wouldnt the $250 earn more staying in the bank drawing intrist than the the pie in the sky investment flip/re-sale of the fixed decrepid firearm?
The worst part is it takes you a couple years to track down the missing used part that may likely be worn and needs to be repaired/built up
Only to discover 2-3 other parts are out of tolerance and it wont function correctly till they are replaced/repaired?
I could see all that money invested if its a hobby you spend the winter tinkering with the old thing and cost dont really matter because its a hobby.
