I just purchased my first Bushmaster and it's on its way (pics soon). I also recently purchased a New England .204 ruger. I love the way it shoots, can't be beat!
I have seen the .204 build post but I am still not %100 sure on a couple things:
1. Will the .204 rounds work with standard mags, bolts, etc?
and leading into...
#2. Is the barrel the only thing I have to replace to convert the weapon (maybe buffer system as well)?
All criticism welcome.
