I have a knight disc in 50 cal which I have had for about 17 yrs it has a 22" barrel and it shoots very well. I was at my local gun shop and found a used knight disc 50 cal almost identical to the one I own so I bought it. The one difference it has is that the newer one has a 26" barrel. I would like to get it cut down so they would be the same. My question is, is this a good idea and is it hard to find someone to do this and do it right?
