Most Helpful Positive Review Worth every penny...
I purchased this barrel for my first build and it never has disappointed. Accurate as Cupid’s arrow on prom night, reliable as a hound dog. I would trust my life with it... It is on the heavier side so if your tryin to keep your rifle light weight this probably isn’t for you, but you would be missing out on the best barrel on the market. So I’m on my 3rd build(2nd AR-15) and tried to find a different barrel so I wouldn’t be having 2 same rifles, BUT I got it down to two barrels and this one was still the best(don’t wanna put any other company’s down but I chose this over the FN equivalent).

DD 18" Midlength 5.56 NATO Very Accurate

by DDfanboi, Verified Owner from CA, United States Written on November 15, 2024
This 18" chrome-lined barrel is very accurate.
Has a 1:7 twist rate and eats 77 grain OTM nicely.
Groupings at 100 yds were 1 MOA.
Shot at 200 yd steel targets and hit most.
It's ~$300 but well worth the investment.
It's a heavy barrel so be ready.
Highly recommend. Can't go wrong.
Shot 223 Rem 55 grain great.
Shot 556 55 grain great.
Shot 556 77 grain OTM tremendously.
I recommend shooting heavy rounds.
Longer barrels deserve heavy rounds.
Pros:
  • Chrome lined barrel
  • acccurate & reliable
  • midlength gas
  • 1:7 twist rate
Cons:
  • heavier than 16" duhh
Best Used for:
  • Scope attachment
  • bipod bench and hunting
Would recommend: Yes

Very accurate 18” rifle gas S2W barrel.

by Bobby, Verified Owner from AZ, United States Written on December 29, 2023
Finally got this zeroed in to 44 yards (due to my sights height over bore being 2.88”). What an accurate barrel!!!! Super happy with it.

Took it to the 500 meter range here that has steel targets at 200, 300, 385 and 500 meters. I was able to hit the targets at various ranges with the appropriate hold overs. I using a red dot with 3x magnifier. All the misses can be attributed to me for not doing my part.

At 200m I was close to dead on and could hit a dueling tree with targets 6” in diameter.

At 300 and 385 I was hitting 10” targets quite easily.

At 500 I had the most misses but without anyone to spot me it was hard. I did see a couple of hits. Again no reflection on the barrel, the misses were all mine.

Overall I am very happy I purchased this barrel. No regrets at all. Definitely would but again.

BTW, I did not do any barrel break in procedures, just took it to the range, zeroed it and then had fun with it. The ammunition I used was 5.56 62 grain.
Pros:
  • Accurate
  • No barrel break in required
Cons:
  • None
Best Used for:
  • any contingency within 5.56 ballistics
Would recommend: Yes

Great Barrel

by The MC, Verified Owner from VA, United States Written on November 19, 2021
This barrel is outstanding.

Pros:  Accurate, Regularly stocked, not the most expensive, 1:7 twist, heavyweight

Cons: heavy, chrome lined if you don't like that

This is the most accurate chrome lined barrel that I've ever shot., and I have shot two separate criterion .223 wylde barrels. This thing is sub-minute all day. With match 75 & 77 grain . 223 and 5.56 this can turn in sub . 50 moa groups. I wish DD made this in 16 inches, id definitely buy it.  It really doesn't feel that heavy to me, but I do go to the gym from time to time. But if it's heavy, a lightweight rail would be a good idea like a BCM rail.  If your used to a 16 midlength govt profile barrel, yeah this is a pound heavier, you may want to stay in the 16 inch barrel length range.
