I've heard that the barrels are not threaded into the receivers, does anyone know if this is correct.
Well edu as you say, you can see it any way you like. Fact is you will have to put thousands of rounds through it and abuse it before it wares out and as a dealer of course you have the right to decline any trade in if you are not happy with it just like the original purchaser had the choice not of buy if it was not going to be the right type of rifle for them.Well Cris, you can see it any way you like, a barrel has a certain amount of shots life span. We as firearm dealers would not take a used "throw away" rifle in as a trade in. At the moment the last 22-250/243/25-06 rifles we took in 50% were re-barrelled due to being shot out. Of course the owners said round count was low, done nothing...bla bla.
I can shoot my fathers rifle and my son can shoot it now too, it would have gone in the bin if it wouldn't have had a new barrel fitted. Now it shoots better than it ever did in it's 50 years.
