Ran into the guy who is working on my Rem VM a few days ago and told him briefly of my next intentions, re-barrelling my oldest AR. It will be two or three more weeks on the shotgun, which gives e a bit of time to plan a route for the rifle. The rifle is well over ten years old and has always been a safe queen due to its barrel length, a Bushmaster Varminter 24" fluted and unlined barrel without muzzle threads. I want to go with a twenty inch barrel on this gun and was wondering what would be a good barrel swap to. My son has shot a couple of really amazing groups from this rifle and wants me to just buy a Bushmaster Predator upper unit for swapping BUT I am not sure I like the idea, I hear the BM line is suffering under Remington?? Though I am not looking for ***** accuracy, I do want a barrel that can do its part for Three Gun when the 16" running gun is left at home. Any thoughts here??
