    I now have two DD barrels (300blk/5.56mm 10.3 inch) and believe they are worth every penny. The quality is unmatched. Not every barrel is created equally!

    Great Performance & Accuracy... Foundation for 300 AAC Blackout SBR w/ Suppressor build. Only thing I would recommend is a Adjustable Gas Block to control the cycling of the Bolt Carrier Group when suppressed! Wish Daniel Defense offered one.

    Bought this barrel for a suppressed SBR setup, and couldn't be happier. It is superior in materials AND craftsmanship over the barrel offered by Advanced Armament Corp, (CMV steel & cold hammer forged, vs 4140 steel and "who-knows-the-process"). It also costs $140 less than the AAC barrel. However, it IS 1.3 inches longer than the AAC, but I figure that is a good trade-off for the superior materials and process. It IS a few more bucks than more "common" barrels that you might find, but again, it's worth it for the quality. There's an old saying: "Buy once, cry once."

    Just shot it recently, and I am impressed. Shoots a ragged hole (1/2in), at 25 yards, and has no problem reaching out to 100yds to hit 3in clay birds. I can also hit the 2 foot plate at 200yds in the same spot repeatedly. I haven't tested it beyond that, but am sure that it is capable of much more precision. In fact, I aim to test it out on paper and post another review. More to come, standby...

    This is the ONE. If you're on the fence about it, don't be. Just pony up the dough and buy it - you won't regret it.
