I’m on too many sites.  I forgot what I posted where.  

I'm debating to build one with a KAC FF RAS with a FSB or another one with a a DD RIS II.

I see black RIS II rails available, but the FDE ones are expected months out.

Tan ones commonly pop up on the EE.

Looks well balanced.

"903215" followed by your individual Elcan serial is correct for Gen3 SU230s.
Keep in mind if you are using CLW, their Elcan Uid's are about an 1/8th of an inch short height wise. (No one will ever notice though)
Also, he has a 12 character limit on the Serial number portion. You can enter the full "903215-xx-xxxx" serial, just add notes saying you want a more "correct" Uid


Pic compliments of CD.

902896 was also used as a serial prefix, not sure when the transition was made to 903215, if one is earlier and one is later or what the difference is. I've spoken with CLW a few times and he can accomodate the 13 characters for the serial on the elcan uids. They are not to exact specs or made from the same material but will suffice.

Thanks, I've been watching for them.

I just missed the last one at Primary Arms, by a day.

Correct, 902896 were used on Gen2 Su230s.

Not just Gen2. Here is a pic of one of my early su230s with a 902986 prefix. 903215 is correct I'm assuming for mid to late models, as all my newer su230s, including my HD models have 903215 prefixes.

Interesting.
I bet that's an early 10 series Elcan.

I opened my MK18 RIS II rail box from Daniel Defense and the rail is sealed in plastic, but I don't see an instruction sheet / card that used to come with them.

The wrench and hardware are in separate plastic bags.

The ladder rail covers are inside the rail.

Are the instructions missing or are they not included anymore?

I did find the instructions in PDF.
https://danieldefense.com/media/asset/r/i/ris_ii_instructions.pdf

The old Lite Rail instructions say the same barrel nut should be 40 ft/lbs.

The RIS II instructions say 55 ft/lbs with the same barrel nut wrench.

Where are the socks

SecretSquirrell had PM'd me that he wanted them... and specifically not to wash them. So I shipped them off to their new owner. Pay it forward as they say.

Brownell's just posted mk18 uppers with handguards minus charging handle, muzzle device and bcg for anyone that's been looking.

yeah i'm tempted.  is there any 10% off coupons out there?  I have one for $40 off.  But $90 off would be awesome.  

Just a head's up... The description says 10.3" but the accompanying video says 10.5".

I wouldn’t worry about that because I don’t think DD even makes a 10.5

Repost but I don’t give a shit, leaf sight and fast in the wild makes my pants tight.

I caught that as well.

I'm pretty sure this rifle has the same operator as the 11.5 URGI that was just posted.

Interesting..

Tempted also...miss the days of $600 after all the discounts.

$40 off code is all I’m aware of right now.  Haven’t seen a 10% off in well over a year.

Just for reference...

I've got some questions about the MK18 FSP upper receiver.  I understand that they were very rare, with not too many of them every made by Daniel Defense.  Were these ever issued?  During which years were they issued?  Are there any pictures of them in the wild?

If I were attempting to build a "clone correct" MK18 FSP, what upper and barrel would I be looking at using?

Do these uppers pre-date cage codes or would one be kosher?  I assume that the barrel must be a cut-down 14.5, but how much grief would I get running a current production factory 10.3 fsb barrel (cage code)?

The answer is no they were not issued.

if you want to scratch the clone and fsp itch try the 28th eod cqbr.

Cross-posting this from the M4A1 Block II thread where I haven't seen any action lately.

For those in the know, were the MRDS used on the Elcans (Insight, Docter, etc.) generally the 3.5 MOA versions or the larger 7.0 MOA versions? I am just curious which size would be considered "clone correct". Note that even if the smaller MOA versions are correct, I may still go with the higher MOA because my eyes are starting to suck.

7.0 MOA just seems like a massive dot size. I suppose for CQB it would be fine, but I'm so used to Aimpoint reticles I couldn't imagine going that large.

I bought the DD Mk18 pistol because it looked cool and the Navy SEALs use it but now I keep reading about 11 1/2 inch barrels like that’s the greatest thing I know it’s only 1.2 inches more. should I feel bad and I keep reading about overgassing.  are these actual practical concerns? I plan on using this as my home defense rifle loaded with green tip. I read somewhere online That although the SEALs use the mark 18 devgru does not. any truth to this?

Oh boy there is allot to decompress in this statement....

quick simple answers.
seals don't use the DD MK18, but they do use more or less the same thing. 11.5 is what USASOC is going w/ in the CQBR URGI. Your dd Mk18 will work just fine but I wouldn't use green tip for home defense. And finally, correct DEVGRU use to use the 416 for awhile and now are moving over to the noveske

I have the rail already and was originally planning to build it up as "clone correct" as possible.  But since they were never issued I guess I have some discretion over what parts to use.

My plan then is to just take a current production cage code upper and mate it with a current production cage code 10.3 fsb barrel and call it done.

Any fault to that logic?

Nah I'd say that's the best route to go.

Nice. If it's out there, cd prob already posted a pic. Definitely not as aesthetically pleasing as the su230, but it's 6x, so that has to count for somethin.  All these recent pics of the elcan that got away (long story) has me jonesin pretty hard. I'll just stick with all my 1x optics until another chance arises.

I hope you will be using a suppressor. You’re not going to want to shoot down a residential hallway without one.

Him: WHAT YOU SAY?!?

I finally started to read through the manual.

(In terrible Australian accent) That's not a cqbr scope, this is a cqbr scope!
id be interested to see what kind of damage the muzzle blast does to the sunshade when fired without suppression.

The most correct thing to do with a Mk18 RIS II FSP would be to use circa 2006 upper, M4 barrel cut down to 10.3", NT4, and early Block II accessories.

Yes, you should definitely feel bad and be worried about it. The entirety of socom that has standardized on 10.3" barrels since the early 2000's basically just have guns that don't work. Every time we go to war with partnering countries our operators usually just line up behind guys with 11.5" barrels so they don't have to shoot their broken, over-gassed guns. Our entire SOF is kind of the laughing stock of the world because of this and nobody takes us seriously. They mostly just use them for "show" at this point, like PR events because they look cool. But in terms of an actual functioning firearm, 11.5" is the only length that actually works.

A lot of the cool guys will just buy 11.5" uppers from Aero, PSA and the like and sneak them over in their luggage and swap them out when nobody is looking.

If you just want to take pictures of them, it's fine, but if you're planning on defending you're home with green tip you might at least want a rifle that works, I.e., 11.5".
---------------
To actually answer your questions:

- It's a short barrel with short dwell time, so parts are going to wear out quicker than on a 20" M-16. But as long as you keep up with maintenance you're fine. Keep it lubed. You'll want to keep an eye on gas port erosion after thousands and thousands of rounds, especially if quickly fired or full-auto & suppressed. Keep an eye on your gas rings. Replace springs at recommended intervals.

- 10.X" barrels, because of their short dwell time can be slightly pickier about ammo than 11.5" barrels, that's really the only practical concern to be aware of. Their "range" of operability is a little bit smaller. Make sure you have a mil-spec barrel with the correct size gas port (.070) and then only shoot military-equivalent loads through it, basically full power 5.56. It may not cycle unsuppressed with lower-pressure .223 or steel case ammo.

- Green tip is a really poor option in general. For home defense look at something like Black Hills 77gr or Hornady Tap 75gr. Green tip is fine for plinking/range ammo.

- DEVGRU has access to alternative supply chains than "vanilla SEALs", so yes, there is truth to that. They have been using the 10.4" HK416 for quite awhile and are currently transitioning to a 10.5" Noveske DI system in both 5.56 and 300 Blackout.

The sass.

This is the cqbr thread. No room for sass in here. Attached File

Where are we getting the info that DEVGRU is switching from HK 416s over to Noveske 10.5" systems? I know all about the spotting of the gen 3 Noveskes with ATACRs mounted but everything else I could find was on Airsoft boards and Japanese gun blogs. Are we sure these aren't just SMU COT purchases?

EDIT:

Did a little searching and it looks like Clasky (who is reputable) is vouching for this.

IIRC the shade hits the front sight so I couldn't completely lock it down. Otherwise, I might have attempted shooting it.

My SASS is the wrong color.

Wait....was that racist?

Never did get my sr25. Probably never will at this point .

Thanks for the replies guys. I admit I am a bit light on knowledge about the AR 15 I bought the Daniel defense iMK 18 because I’m worried I won’t be able to buy an AR pistol in the next few months. I really wanted a shorter barrel HKMR556 but I don’t we’re ever going to get it because everybody on the forum says HK hates us.
