Buy it & enjoy it! I have a field grade I got from CMPicon that has a couple of other Win parts in it.
It shoots great & I have used it in matches. The other I got at auction & appears to be a Danishicon return as it has the sighting label in the barrell chanell & a lot of Win parts. It also shoots great. You will have a good shooter, you can pick up parts here & there if a good price
& you can correct slowly. You may never get it correct, but you will learn & enjoy.
