receiver/barrel thread problems?
So im finally getting around to swapping barrels on my stevens 200. Going from 223 to 300 blackout. I bought the barrel from the gun shack during the group buy. I got the old barrel off, but the new one wont thread into the receiver. The barrel nut goes most of the way on but stops also. Im not the trype to force things so i stopped when it got tight. What are your thoughts on this? Chase all the threads to even them up or have a gunsmith take a look at it? Sorry for any typos, im writing this on my phone.
One more thing. I took the scope base off before i started.
