Yeah, definitely. Part of the reason I prefer factory DD 10.3 barrels even if a chopped Colt would be more accurate. I've seen quite a number of chopped barrels where the shoulder didn't match the RIS II; clearly they were more like 10.4 or 10.5, and that would really bother me. While it's certainly not something I would want in any case, I could live with it a bit more on a Mod 0/CQBR Block I. On a Block 2 it just stands out like a sore thumb when the shoulder isn't even with the rail.

ETA: I guess you could say the same about an incorrect barrel length sticking out on a Mod 0 because of the bayonet lug, but until I replace the 10.5 on my Mod 0 I like to pretend it's really not that bad, lol.

As far as I know those specs are completely accurate. @Pezboytate would have to chime in with exactly the source, but they should be correct.

But to me, and likely most people here, the difference between 10.3 and 10.5 is pass/fail.

Has this schematic been vetted for accuracy? If so, will be really helpful.

It was correct at least at one point. I can't say that all of the barrels were cut to that spec or not.

If you cut a barrel to exactly 10.3" with a .63" thread length, it will be too short. Crane cut down barrels are about 10.35" with a .60" thread length. Colt 10.3" barrels are about 10.38" with a .63" thread length. The problem is that ADCO and others don't know this and they probably don't care.

The mod 0 was an adco job, and it really appears more like a 10.5 than a 10.3. to me. The mod 1, I was told, is factory, but I have my doubts  based on the marks left on the barrel. Only a date, no c mp or 13629 which leads me to believe it's chopped. The shoulder of the barrel is even with the end of the ris ii so, I'd say it is spot on.

@milspec556 besides avoiding having to cut down a precious rail ladder, I have the sight that way for ease of access. As I was  installing it, I noticed how the design almost begs to be placed like that. It has wigs to protect the sight ears, which is useful more so when placed like that, and the under side has a recess cutout to aid in flipping the sight, which is basically lost when it's placed like a std sight. I'm not sure if there is a right way, but that works for me. I honestly thought I'd get more flack for a qd in place of Cqd or the m900. Honestly, I'm just glad to have a rail that the 99051 can feel home on. Even if it's makin room for a rail ladder.

eta- if I had to guess based on shoulder of muzzle to bayo lug distance mine is close to a 10.4(mod0).
The bottom barrel is the colt cutdown by adco (through previous owner). Note: the tan ring of paint is on the fh, not the barrel. Adds the illusion of being even longer than it really is. Need to strip it but not really bothered by it enough to do so.

All my replacement barrels that we have received from Crane for rebuilds have been Crane cut down Colt Govt profile 14.5" barrels.  Haven't received any in a year however and the last few were new FN SOCOM profile 10.3".  On leave right now so won't be able to measure for a few weeks.

I'm about to finish the Mod 0 and planned on the classic look with LMT rear sight Comp M2 with a Wilson mount.  However, I have trouble with Aimpoints.  The dot looks like a blob.  I was thinking of a TA01NSN for the Mod 0 with a Matech rear sight.  Thoughts or alternatives?  Thanks

Same here. But yeah it has always been Colt 10.3 govt, throughout the Mk18 Mod 0, Block 1 CQBR, Block 1.5, and most of the life of the Block 2/Mod 1. The FN 10.3 SOCOM is something he found this year. Pretty awesome.

Yeah the problem for us with FN is due to TDP rights their commercial products and mil products have to be manufactured at separate factories unlike Colt. Since they snagged their lions share of the last M4A1 contract they make military SOCOM 14.5s and now SOCOM 10.3s, but without sourcing "fell off the back of the truck" barrels, we are stuck with their commercial stuff. Which is a major bum deal.

The early barrels were Colt barrels cut down by Crane to 10.5". As far as any LMT barrels go there is only one purchase documented for 40 10.5" barrels and there is a question as to whether any actually made it into builds or were just for testing. Once Colt was contracted to supply the short barrels the length was revised to 10.3".

I would tend to agree but everyone knows the the first barrels were Colt barrels cut down by Crane.  However based on the article I linked to the Crane cut Colt barrels were 10.5" and were revised to 10.3" only when Colt started supplying the short barrels. From this I would have to say that there were either 10.5" barrels fielded or that none of the original Crane cut barrels were fielded.

Based on the acknowledgments at the end of the article there is little doubt that these people knew what they were talking about.

Crane is still cutting down Colt barrels for use in CQBRs, that never stopped as far as I know. Crane cut down 10.3s are still being supplied currently as replacement barrels for CQBR URGs along with some FN SOCOM 10.3s that have appeared recently. I'm not 100% sure if new URGs come with cut downs or factory barrels, but Crane cut barrels are definitely still being supplied for replacements. Either way, you'd have to be cloning something very specific and very early to get away with a 10.5" being acceptable.

We've had pics here of URGs directly shipped straight from CRANE as received, brand new. Standard chopped 10.3 Colt govt.
@Combat_Diver in your supply system can you request full CQBR URG's from CRANE as well, or is it only for the individual parts that you normally order and receive?

Yeah, I thought so, but couldn't remember for sure. You'd think Colt factory 10.3s would be used in some capacity, but I've never really gone looking for that info specifically; no idea if it's all cut downs or a mix depending on availability on current CQBR URGs. Either way, Crane is still supplying chopped barrels, so there is no question that Crane cut barrels were and are currently being fielded. Just not 10.5s.

'Cept for mine, you see. My 10.5 is currently being fielded in the mountains of Arizonastan, and has been "seen in the wild" quite often. Feel free to clone away ;p.

The walrus visited me one night and I woke up the next morning to an email welcoming me to ARF. No idea that I did it and the first thing I noticed was that my name was misspelled.

Same thing happened to me and FB. Minus the misspelled name.

@milspec556, I think I figured out what happened to this guys handgurd mount up system. I think this is what happens when you have an ris ii mounting bracket behind the barrel nut, and try to force a dd lite rail to fit. I have an o.g. Dd lite rail, and thought I could just slip it off and install the ris ii.... Nope. They don't line up. Almost cross threaded/ stripped out the mount. The top four bolts lined up, but the bottom was off. Made me wonder if the same thing happened here, just vice versa. So I guess the lesson is, if it didn't come with the rail, don't try to mount it? Although it appears to be working for him.


Eta: I'm glad the dd lite fsp that was in the EE finally sold. I do not need another rail/ build.
eta #2: is that a sf mini on the end of his muzzle?

I noticed we both have a first gen m951. The one with the older mounting bracket. Mine has the sw02 tailcap, but I do have one of the tail caps that yours appears to have. I don't think I'll ever sell that one.

Cancer can wait. Workin on multiple sclerosis currently. Wife was diagnosed 4 years ago and it has (been) rough! Drs don't know what causes it and no cure in sight. Any way, one thing at a time. (The cure for cancer was vegetables all along! Momma was right to make us eat  our veggies, but terribly wrong to reward us with Micky d's!)

edit it to correct grammar

I don't even know half of what lights I've got. I see one I like, buy it, play with it for a while, then toss it in the pile.

Just found a ti-7 pic. I recently got one for a friend, and I mounted on my cqbr, and it's great. The rounded heel of the buttstock feels great when shooting heads up. I'm likin em more and more. Plus the placement of the adjustment lever is nice, and to take the stock completely off, you just pull the lever the opposite way. Easiest one I know of to remove.

Eta: check that finger placement.

Chop that front grip
Chopped KAC vert grip you say? I did mine the other night, still needs some work but I like it so far. I know the rifle doesn't fit the thread so please don't flame me to hard.

I don't know what anyone else thinks, but we've had a pretty good (and pretty rare) run of excellent first rifle pics.

Great stick, thanks for sharing!

A Black peq is better than invisible! If you squint hard, i mean really hard, till your eyes are completely closed, you'll see it. Why else would my 99051 be on backwards? The guy I bought it from said its Fde, but I honestly can't tell. And I didn't realize the invisible ones cost almost twice as much as a visible one. Somethin to do with extremely limited runs.

I have tried searching high and low for some rough numbers here for a comparison I'm doing but strangely found nothing. So, could a couple of you chime in with your rough unloaded weights of your Mk18 CQBR rifles that are fully outfitted with optics, IR laser, suppressor, etc.? I realize there are an infinite number of variables here, but I'm looking for a rough approximation. Thanks!
