Hi guys I’m starting to collect pieces for the gun on the left. The optic is kind of throwing me off, I think it’s a x24 NF but the resolution sucks and the eyepiece and the knobs look off. Anyone have any other pics of this gun?

Looks like an x24 with a duct taped BC cap.

The guy without his face blurred is Bill Rapier. The guy is total badass. From knife work, Jujitsu black belt and one of the best shooters at DEVGRU. He was also on the UBL raid. Very humble guy. Owns his own shooting/defense business in Idaho now.

Getting back in the game. Who makes an off the shelf barrel that allows for the smallest rail to suppressor gap with a standard AE collar? I went with a BA 16", had it chopped to 15.1" and pinned and welded. Got it back and it had more gap than I wanted, so hoping for better results this go around. Picture of my previous upper.

You may not be able to hit 16" with a P/W and have a flush fit to the rail. Not sure on the math.

I've got 2 sets of MA110 rings sitting here and I'm not sure which set to use for my OG SEAL build with 2.5-10x32 scope. The set on the left is pre-2010, the set on the right is 2010 to current issue. There's subtle differences between the sets, I'm trying to figure out which set would fit the time frame for my clone build. I'm assuming it's the pre-2010 rings, but I'm not certain. Here's some pics:






Also, I have 3 of the x32 scopes, but 2 of them are .25 MOA turret adjustments and the other is .1 MRAD. I know the SEALS used the .25 MOA turrets on their other NF scopes, but did they ever use the .1 MRAD turrets? Or was that an Army thing?

MOA/MIL would be more correct I'd assume for that time frame. If your actually going to shoot it a lot and go past 600yd I'd put the MIL/MIL on there. The 5 MILS on the reticle would get you out to 600 with heavies no problem.

Pardon my ignorance I read this thread about 10 pages or so and then I got tired I can’t figure out where the NSW Reece/recce  is. I searched GunBroker for NSW nothing came up I know that Noveske used to make a Recce”. You guys seem to be referring to an AR with varying length barrels a suppressor a multi power optical site and collapsible stock generically as an NSW no matter what the maker- am I correct about us ?   As for me I thought that NSW used the HK 416 because of its piston design. Now it looks like they’ve gone back to previous designs. Am I right? Then I see the Daniel defense mark 18 sold as “used by socom”. Not trying to go off on a tangent but what is the tier 1 rifle is most commonly these days or a mishmash based on each individual operators preference.  Until I recently figured out I could buy an A.R. pistol I could never dream of having a weapon similar to that used by special forces.  Frankly when I clicked on the thread I thought it was people making short barrels or pistol versions of the HK 416 making kind of no easy day Devgru replicas

First post is pretty all-encompassing. They all used 15.1" or 16" barrels. Minor variations here and there, but it's put into a pretty small box.

- Recce is just slang for "recon", so this is just a recon rifle. It's not an actual brand of rifle, it's just a somewhat specific configuration that was used for a time inside of devgru. It's similar in purpose and capability to the SPR or Mk 12 family of rifles. Basic idea is just a fairly accurate M4 using specialized ammo. It's still being used today because it's a capable platform and meets needs that other systems don't.

- The varying length of barrel, and suppressor, etc… is because the rifle/configuration varied over time and over different groups. But generally the purpose of the rifle is the same.

- They didn't use the 416 because of its "piston design". They chose it because it met their needs. They haven't gone back to "previous designs", they've just chosen a different carbine that meets their current needs.

- The Mk 18 has nothing to do with this thread. It's an issued 10" carbine within socom. Vanilla SEAL teams get it, but it's not used within devgru (different weapons altogether). There are a few photos floating around where individual operators have set Mk 18s up as "recce rifles", I.e., adding a Nightforce, bi-pod and moving the laser off to the side so it's compatible with CNVDs. So you could make an argument that that's technically also an "NSW Recce" but it's not really what this thread is about.

- The no easy day carbine has nothing to do with this thread. That would be just a standard issue dev 10.4" 416 set up as an assaulter-style configuration (EOTech, etc…). But again, plenty of operators have also setup 10.4" 416s as "recces".

- If your goal is to own a clone of a rifle used by SOF, then decide what you want to do with it first. If you want to be clearing rooms or primarily shooting up close then something like the Mk 18 or a 10" 416 would work great. If your goal is to be out shooting on open land past 200yds then something like a recce or Mk 12 is a great option.

Which begs the question, 15,1” or 16”, and why? Which was used in greater numbers? The reason I ask is, I had Kevin build me up REECEish 16” a number of years ago, using URX3 with a 16” SS barrel, profiled for my OPS brake and collar, well I kept the barrel (unfired) but sold the URX, I now have everything to correctly build a NSW, REECE except my barrel needs to either be built as is, or send it to D Wilson, have it shortened and reprofiled.

Idk about "seen in greater numbers", but a 15.1 with the KAC RAS, iirc, will bring the suppressor damn near touching the handguard. Pretty bitchin' look imo. when i get around to a Recce, that is what im going to be going with

There are no ITW pictures of a 16" NSW Recce with a 12th model attached

If your planning on running the 12th/AEM5 and want to stay clone 15.1" is what you will want.

If you want to run a 16" then the Lilja/249f/NT4 would be clone correct.

With that being said the NSW Recce with a 16" and the 12th/AEM5 is still a very good looking rig and plenty of guys in this thread are running that setup.

If I were you I'd chop it to 15.1" before the build. That gap will bug you and it not being a true clone will also bug you. If that matters to you.

My old Mod1 has been rebuilt into a 16" recce. I shoot with @Eyekahn all the time and while it may not seem like it, that little bit of length does make a psychological difference, if nothing else. The NSW just feels a slight bit more handy and maneuverable. Both look great, and I see no good reason to go back to an 18" barrel as the ballistics aren't that far apart, but there is a difference between 15.1" and 16" and there is certainly a big difference in those vs. the 18" Mk12 platform. All are great, however.

I feel the same way.. My Mod 1 doesn’t get much love at all and sits there collecting dust.. Was planning to go 16”, BUUT I already have a 15.1, any reason to have both 15.1 and 16 NSW, other than just because... lol

Not at all ha. 15.1" is life.

I will say however if you have the means to keep a legit MK12 in the stable I would do that, if not for anything else but the sound alone!

Is that double rings? Does it have the same footprint as the rmr/507?

Both look great, and I see no good reason to go back to an 18" barrel as the ballistics aren't that far apart, but there is a difference between 15.1" and 16" and there is certainly a big difference in those vs. the 18" Mk12 platform. All are great, however.

Did you notice any difference between the mid length and rifle length gas system? I would think the rifle length would have a slightly softer recoil impulse...yes/no?

Double Rings..?? It’s just a 3.5 MOA Dot, and NO the Mount is compatible with Docter, FastFire, Vortex Viper/Venom.. Just to name a few..

@SSOUNN I think by double rings he meant the Docter is on its own ring, and not attached to the scope ring. The answer is yes. That ring can be mounted anywhere along the tube and rotated around it wherever you want it. That rifle is titties!

I need to decide which route to go. I already have a 16" CLE, but I have the Armalite tube over that. Seems silly to get a 15.1 also. The Lilja seems like a logical route for me

I'll chime in. It's a small difference but noticeable. It's much more noticeable when you have rifle gas and rifle buffer.

An H2 with sprinco spring with the middy is perfect for something like this.

A 15.1" with AEM5 is about the same OAL as an Unsuppressed MK12. The NSW without can is only .6in longer than a standard M4. The handiness of it really outweighs that TINY bit more felt recoil.

I had a picture of my NSW and J's old MK12 lined up. Can't seem to find it though.

If you already have a 15.1, convert the 16 to an 11.3 mini.

Negligible difference, I'd say.

There’s part of me that want to chop down my mod 1 to go along with my mini NSW recce but I have a block II setup as a recce that’s a nice shooter. No need for two rifles within .6" of each other. Something about the mod 1 and the exposed gas block that I can’t get rid of it. Maybe I’ve watched lone survivor one too many times.

I did some research and found the BRT eztune gas tubes. I didn't want to bother with taking off my gas block and installing the BRT gas block screw. Based off of their recommendation from my setup (Lilja M4 barrel, 0.080" gas port, carbine gas, G42 spring, H2 buffer, and using 77gr 5.56), I got a tube that had a 0.0625 hole. The difference in size between the standard gas tube hole and the BRT is pretty crazy. Installed it and got to test fire it today. The recce now shoots much softer and the casings are ejecting at exactly 3:00. I know the ejection pattern doesn't really matter, but the rifle isn't as jumpy and my crosshair isn't bouncing off of the target as much. Overall highly recommended if you have a Lilja m4 recce build!

Just found this post.  I have the Lija and know of what you speak.  I asked Carson Lilja (Dan's son) about that port size.  He says the background on the hoggish .080" port is lost in the mist of time but that this is how Crane spec'd it.  Maybe they just wanted to make damned sure the thing would cycle under any conceivable operating conditions, softness be damned.

I have sub 1/2 MOA match loads with light 52 grain Bergers that have the best accuracy node down at .223 pressures.  They cycle reliably and ejection pattern is about 3 o'clock.  So, I've not tackled the serious over-gassing with 5.56 power 77 grain SMKs.  They do really snap, for sure.  

I was debating an adjustable gas block or insert.  Didn't know someone was making a correctly sized gas tube.  Thanks.  I'm going to try that.  Thanks for this information.

If you have a B2 Recce I'd leave the mod 1 alone.

If you were considering ditching both of your setups I'd replace both of them with a 15.1". That's exactly what it was made for!
