Daniel Defense Licensed CNC Aluminum Outer Barrel (Model: 20" Government Profile)

"This outer barrel is great, I loved it I used it to build a mk18 . It fit great I had no problems at all if I need another I’ll definitely get another . This will fit great on any m4 upper receiver although the back piece shows black on the picture but it’s like Grey it shouldn’t matter though you can’t see it

"DOES NOT FIT THE NEW GEN HOPUP

Other than that it's nice looking and seems to be a strong and pretty good barrel. Just beware the hopup stuff I mentioned.

"Fit and finish are great! Looks quite nice and realistic on the end of my G&G M4, even with the stock rails. Need a low profile gas block to finish it out, but works great! Definitely love it!

"This outer barrel is awesome!! It's lightweight, strong, good tolerances,threads are beefy (tight tolerance) and has real markings on the barrel. Overall it's a great barrel! My two complaints about it is my outer barrel is not completely straight with my mk18 rail; It sits slightly upwards. But I believe it could be my receiver making the rail to not sit level making the outer barrel to appear that it is sitting flush. Second is the barrel is a little short to fit a thread on matrix suppressor. It's work but it rubs up against the rail when using a Daniel defense mk18 rail with it.

Pros:
Solid

Tight tolerances

Lightweight

Only one on the market that is the correct outerbarrel for a Daniel defense mk18 rail.

Real markings (twist, caliber, etc)

Cons:
Tad short for a suppressor when using a daniel defense mk18 rail. Works perfect with flashhiders

Little bit expensive

In my case the outer barrel is not straight with my Daniel defense mk18 rail.

"I got this outer and it seemed to work great. No problems at all. I didn't have any wobble like the other guy maybe he installed it wrong or something?? Well it's great and would definitely reccomed it.

"Great barrel.
Looks great, works great with the Madbull 12" Daniel Defense Rail system and my G&P receiver.

Feels solid, no noticeable wobble.

"Great quality, doing a mk18 build and it's exactly what your looking for if doing that build. I've had no issues with the finish rubbing off. Does seem to wobble a bit will have to disassemble to get a better clue as to what's going on with that.

"Fits perfectly in a G&P body. Light weight, very high quality, looks amazing. Make sure you tighten both the top and bottom allen screws before installing the rail or you will feel REALLY stupid when the main part of the barrel slides out after you put your rail on.

pros:
very sturdy
easy and smooth install
trademarks (not that most people will see them)

cons:
none yet

"I have no idea what the guy above me is talking about. i have thrown this thing against a wall (not on purpose) and there is not a scratch on it.
Very well made.

"I absolutely love this barrel incrediably realistic and almost to light!

Pros:
Realistic finish
durable
reasonable price
very light
I am always the only one at my field with a 16in barrel which makes my gun stand out

Cons:
honestly cannot find one great product and lots of choices in length, prsonaly prefer the 16in

P.S.Looks great with a Daniel Defense 12in rail especialy if you like the Larry Vikers look.

"Works well, is made out of solid metal, but to fit it in without it rattling around I had to put some duct tape behind the insert that you put into the upper receiver. Its also quite heavy. Other than that, works great!

"A good barrel, very nice quality construction.

But it does have 1 flaw.
The notch were the hop-up unit is supposed to go was not wide enough for my stock hop-up unit nor the Pro Win hop-up I bought. I was able to fix it by filing down the sides of the notch until the hop-up unit fit.

Other than that, some sticker paper residue was left on the barrel from the factory.

4/5

"My barrel didnt even come with anything to secure it to my m4, i am doing s mk 18 build so the mk18 ring holds it a little bit but the barrel is still loose, I must be doingsomething wrong

"So I just got this today for my Mk18 mod 0 build and as I was putting on the triangle front site the finish was practically rubbing off, now there are shinney spots where there is exposed aluminum. Needless to say I'm not very happy. Especially since its $41.00. The least they could have done is pit on a decent finish. It's cool that it comes with DD trades and whatnot, but you can't see them if you have a rail or anything over the barrel. And there are two set screws on the base of the barrel and mine came with them loose. Overall only get it if you are building a Mk18. Now for the pros and cons.
Pros:
Licensed and trademarked by Daniel Defense
Milspec 10.3" long
Cons:
Price, $41 is too high
Set screws were loose
Finish rubs off very easily.

"TERRIBLE BARREL. UNLESS YOU ARE USING A DANIEL DEFENSE RAIL, IT WONT WORK WITH ANY OTHER AEG BARREL NUT EXCEPT A DELTA RING. EVIKE NEEDS TO UPDATE THIS PAGE TO NOT SAY COMPATIBLE WITH ALL AEG.

NEVER BUYING FROM MADBULL EVER AGAIN. OVER PRICED GARBAGE.
