Just an extra data point on this - I’ve had a DD RIS II barrel nut with similar “gaps” in the grooves. Posted a pic of mine a while back and the general consensus was that it’s been seen before and a non-issue.

Did he lose a golf ball? That's gonna be a tough shot to make. Looks like a double-birdie-bogie.

Good to know. The fact that CD has changed countless barrels, and never noticed the gaps leaves me with two possible conclusions: 1) DD sends all the good barrel nuts to fulfill gov contracts and we get the wonky ones, or 2) CD has been avoiding the eye dr for too long. Just playin.

The muzzle device, sling and optic are a start. Probably fits better in the pistol thread.

I believe they have their own thread. In my opinion, 10.3" is what makes this thread. The 10.4" 416's have their own thread, and the urgi thread is a mix of 14.5", the unissued 10.3", and I assume 11.5" are eother already there, or soo, to be there. Im curious to see what everyone else thinks about it.

These threads have no rhyme or reason lol

Edit: we got the Block 1,1.5,2 thread which covers basically all 14.5 sopmods and mws, Block II , URGI for 14.5 &11.5, the mk12 thread, mk12 mod h, recce, etc...

When probably it should just be Block 1 10.3/14.5 (can debate wether mws is included), Block II 10.3/14.5, urgi 14.5/11.5 etc

Yes, that's basically what I said in the M4 SOPMOD thread.

A Block I CQBR has way more in common with a Block I M4A1 than it does a 10.3" RIS II URG.

It is what it is though.

That's just the way the site is. The threads mentioned will still be around even if we agreed upon and started new threads with said parameters. Since each thread grew from a need that wasn't getting met from another thread, there really is no rhyme or reason. Don't forgot that there are 3 iterations of this very thread.(not exactly this thread, but you know what I mean.) That said, I agree with your conclusion. (Oh yea, almost forgot we even have a GWOT thread that covers just about everything posted above )

My recently acquired 10.3" FN barrel looks to have a gas port smaller than my previous one.

The other is now assembled, but I don't remember it being smaller than the Colt gas port.

The gas port looks like it might have been drilled after the barrel was finished and may be standard 14.5" M4 barrel size.

I'm tempted to open it up before I assemble it.

I don't have any pin gages that size, so I'm going to get a few numbered drills and check it.

Is this a common build issue?

Just picked up a factory DD mk18 upper I’ve always thought mk18s looked pretty sick and my LGS had the upper in the glass display I saw it once in there and it kinda nagged at me so I went back for it $899 for a stripped upper is kinda meh but I wanted it

Took it out once so far to test and zero and what I can say so far is it’s so well gassed I had my DA  Nomad on the front and barely noticed any gas to the face what so ever with Wolf steel and gold it shoots so smooth suppressed

It will not be very clone correct or anything like that with a T1, Nomad, Dbal D2 and a Modlite but I’ll post some pics when I get it all slapped together



I gotta say I’m a disappointed to look and find that it uses a set screw gas block but that’s what I get for just assuming it was pinned and not giving buying it much thought beyond “hey that’s super cool I want it” but apparently they were issued that way so no biggie .... does anyone know if DD uses a specific thread locker and if they dimple the barrel?

The 10.3" barrels are now dimpled for set screws.

The set screw gas block should be the Daniel Defense black stainless MK12 gas block.

It is sold with military specified red Loctite 262, but the instructions recommend blue Lotite (242).

I think I'll let someone else have this one. I'm just looking for another that's used a bit more and priced accordingly. For example, I actually got one a few weeks ago for 2 fiddy .

Needed- no but are good to have on hand if your bolt stops extracting correctly
Clone correct-no not that anybody would know since they are just small
I like having a few BCM sopmod bolt upgrade rebuild kits on hand.
