What is the gas block diameter for this barrel? 0.75" or other? I really want to get this, but need to know first. Will it fit my DPMS Oracle A3 LR-308 upper? It currently has a heavy barrel profile 0.75" gas block diameter, carbine length gas system. I know this will be longer at midlength so I need a new gas tube too.

BEST ANSWER: I have several of this exact barrel. With 168 grain Sierra Match King they are all sub MOA. With mil spec 147 grain rounds about 1.5 to 2.0 MOA.
Is this barrel compatible with a DPMS upper and BCG?
Matt B on Jun 2, 2018
BEST ANSWER: It worked with my dpms style upper but make sure you go with a bcg that matches your upper. (My bcg don’t line up with my forward assist but cycles just fine)

Goes bang every time, has mediocre accuracy but looks very nice.
I bought this barrel with the plan to make this a mid range carbine out to 300 yards, barrel looks very nice and assembled easily, but..... with GOLD medal match, Winchester 308 150 grain soft points, and my own 168 grain handloads, this barrel only was able to produce a 4 inch group at 100 yards. May consider replacing in the future.
