JUST RECEIVED IT TODAY. I MEASURED THE BARREL AND IT'S 10.5". NOT SURE WHY IT'S ADVERTISED AS 10". ONLY MARKINGS FOUND ON THE BARREL IS 5.56. NO TWIST RATE ENGRAVED. QUALITY SEEMS DECENT.
Best 75$ Nitride Barrel you can get
This was put on my new AR pistol. I was a little hesitant because it was such a cheap barrel but Diamond Back has surprised me significantly. Shoots great and on target. Shot 500 rounds of 5.56 FMJ 55gr through it to break her in and not problems. Of the 500 shot four were out of my clusters.
DB 10 inch carbine barrel
This barrel is spot on! Been getting one inch or less groupings consistently
