This should probably be posted in the black rifle room, but since it is a supporters only room I wanted to open it up for more to comment on. If the mods think it is more appropriate there, please feel free to move it. I have one of these LR-308B. When I bought it suppressors weren't really on my radar screen. Now that I have a specwar soon to be released from NFA jail, I would like to use it on this rifle. This bull barrel model did not come threaded. My question is this, my LGS where I bought it from says they can thread it for $100. That is not bad, but I would really like to know about the quality of the DPMS barrels in general. Where do they rate say on a 1-10 scale as far as quality and accuracy goes. If these are rated towards the high end, then I would keep it and have it threaded. If they are below average then I would rather put the money towards a match grade barrel that comes threaded. This gun does not get a large amount of rounds through so I don't necessarilly need something chrome lined for high round count or low maintenance as I clean it after every session. Your recommendations are appreciated.
