Most Helpful Positive Review MK12 Gas block
If I weren't trying to build an accurate clone of the MK12, I would not have spent 3 times the price for something that I can get for a lot less and that works the same. Its of good quality and has a good fit. Finish isn't anything special but it is just a gas block.

Usual DD quality you’d expect. Tight fit and quality fasteners.

Exactly as described

by Burt, from WI, United States Written on March 2, 2021
Quality MK12 gas block from a great company, that actually has/had the contract for this gas block for the military. Optics Planet had it in stock when no one else did, and at the normal price. Included everything needed; loctite, set screws, gas tube roll pin, and allen wrench for the set screws.

Good Low Profile Gas Block

by C.S., Verified Owner from CA, United States Written on September 26, 2020
I am using this gas block with a Knight's Armament Co RAS free float long rail. The gas block is low profile and it fits well underneath the rail. It's made of steel and it's made in the USA so you can't go wrong with that.

MK12 Gas Block

by Jon, from OH, United States Written on June 26, 2020
This gas block was purchased for a MK18 inspired build. I assembled the item onto a 10.3 inch Daniel Defense barrel. It was a tight fit to get it into place, but once the hex screws were locked into the block, I was confident that it was secure and will not budge.
Pros:
  • Durability, Construction
Cons:
  • Tight fitting on first install
Would recommend: Yes

Daniel Defense Mk12 gas block.

by sgtkmk, from WA, United States Written on May 25, 2019
Fit and finish was great. If you are looking for the "correct" part for a Mk12 SPR or similar build this is the part you want. The packaging includes the block, the set screws and loctite. I don't know if the description from DD stating they make these for the Military is correct or not.

MK12 gas block

by Barry, from MN, United States Written on March 10, 2019
Great price and lightening fast shipping! This gas block is the perfect addition for a URG-I upper. Daniel Defense is a proven supplier to USSOCOM and this gas block is the mil-spec standard used in the MK12 SPR rifles and the new URG-I uppers designated for the US Army.

DD MK12 Gas Block

by Rhetorical Duck, from FL, United States Written on November 17, 2018
Chose this gas block for a MK12 mod H clone build, quality is very good and I trust anything from Daniel defense. Fits snug and securely on a BA 16" barrel, had to lube it with some WD40 to get it on and move it around. Only downside to this gas block is the price, its a little high for a non adjustable gas block but it is clone correct for a MK12 build and MK18 and definitely will be buying again for a MK18 clone build.
Pros:
  • Quality build
  • Clone correct for MK12 & MK18
  • Comes with thread locker
Cons:
  • price is a bit high
Best Used for:
  • MK12 & MK18 clones
Would recommend: Yes

Mk12 gas block

by Pumpymagnus, from NH, United States Written on January 23, 2018
Great product and the fit and finish was excellent compared to other similar products. Perfect fit if your using a DD RIS II rail for a M4A1 or Mk18 build. This will also work for a MK12 mod 1 build. I recomend this low pro gas block over any other one out there. Optics planet had the best price and shipping rate.
Pros:
  • fit and finish are flawless, sleek, well made
Cons:
  • None
Best Used for:
  • M4A1 MK18 or MK12
Would recommend: Yes
