Are these worth picking up? At that price it’s hard not to want to grab one or two for a build.
i cant believe they still have some…
yes, they’re most definitely good barrels. DD switched to CHF barrels shortly out of the gate, so they clearanced all their standard barrels.
i’d have bought a stack of 'em, back when bravo first put them up, but money’s been tight lately.
They must have been good because they are gone now.
maybe i got the last one. 
Brownells still has some.
