So what makes the SIG optic better than the Vortex? Reticle? Weight?

I can only speculate, but let's assume the Razor was competing alongside the Tango6 in the SFP component of S-VPS solicitation. While unlikely, it's entirely possible that Vortex outperformed in every category except price. Sig had just previously been awarded the Squad Designated Marksman Rifle optic contract and after the S-VPS would go on to secure the Army's Direct View Optic selection. So on the contrary it's fair to argue the Tango6 has merit from multiple evaluations.



Perhaps a more interesting subject matter is the inverse of your question: Why would SOCOM purchase the Razor 1-6x (adopted as the SU-300) when it already had a new SFP scope in the pipeline?

Again, this is only conjecture. I believe it came down to timing and availability. The Gen IIE's NSN was established in November 2020, two years after the Sig was selected in October of 2018. Yet we're just now starting to see Sig's get fielded, whereas the Vortex scopes have been prevalent for some time (though exclusively with Rangers.)

The Leopold protest and resultant litigation caused a delay in procurement of the SU-293 that Regiment seemed to have been unwilling to wait for. That, or maybe USASOC never intended purchase of those MAS-D optics for the 75th to begin with. For that matter I haven't seen any ATACR's in their unit either.

In whichever case, the adoption of the Razor comes as a result of Rangers being forced or simply choosing to do their own thing.

Is that a Modlite head?

Not just a head that’s the whole light.  I’ve seen a handful.  

75th Ranger

That's a fuck ton of glass for a 14.5" barreled rifle..................................I bet that bitch is heavy especially with that raptor up top

Back to the weight room

It’s killing the die hards but tech the industry as a whole has finally surpassed the old days of self innovation and there are no longer rules in the clone game aside from a specific barrel really.  Build the bitch the way that works for you just like units do.  I love it the possibilities are endless and minus a few specific parts clone game is fun again

Sorry if this has come up but are non cage code Colt uppers making it around inventory? I have a spare one and was debating using it for my URG-I but I'd rather wait for the numbers or use a Mueller instead if it ain't fully correct.

Going back to the Tango6T.

So the DVO FFP is NOT correct anymore? The SFP 6T will be correct going forward?

I would say 95% URG-I uppers are non cage coded.  Remember they were rebuilt using existing uppers off URGs already in service.

CD

Anyone remember what page the correspondence with the vortex rep was on regarding their contract 30mm mount? Hell of a time trying to find it.

254.

They didn’t say much:

GBs

Thank you very much, I thought it was in the 100s but I was dead wrong.

Wow!  Is that a Vortex Crossfire in Pics 1 and 3?  I haven't seen those issued.

So is this an actual mil spec ATACR, or just a mil spec  illumination cap installed?

Am I going to get a clone demerit for having my razor in a 1.93” reptilia mount?

Any reference pics knocking around out there or should I just sell/trade it for the G?

Not issued. Probably unit or personally purchased.

I got 2 of those on Unity mounts, so I can have a budget clone optic.

Quick question - have they tested the Razor Gen 2 enough that they've decided backup irons are not needed any more? I don't see them in the pics. Thanks for any info.

I don't think that decision has been made specifically in regards to the Razor, but it is common to not see backups. I believe the decision has more to do with a command's policies on the matter. Reminds me of something I heard about 15 or 20 years ago when one of the MEU's required their Marines to have iron sights on their weapons at all times so there were a few pics of guys with an ACOG up top and a carry handle in an obscure location on their M5 handguard.

Also, with fewer and fewer QD mounts out there, it's a bit of a hassle to take your Geissle or NF mount off in order to flip your irons up (but you should have the tools on hand in case you do need it off). That's why offset sights, whether red dot or irons, are pretty popular.

The DVO is an Army program for their infantry M4A1's and NGSW. SOCOM has redundant capability with the SFP S-VPS. So it's unlikely you would ever see a DVO scope on a URG-I. But who knows, check back in five years once some National Guard SFG unit has had time to do weird things.



Given the previous assertion these all roll off the same line and assembly process, what's the difference? The only thing I can tell you for certain is that it came from Night Force this way.

I'm surprised no one has posted this yet: FDE Mark 5HD

I believe that is an actual MILSPEC ATACR.So I just dove into this for a different reason. I had to talk to people that use these scopes.  The MILSPEC marked battery cap is on ATACR's that are issued to non SOCOM units. The SOCOM contract scopes like Nightforce just released have non marked stepped caps and are FDE. The commercial ATACR has " ATACR 1-8X24 F1" on the battery cap. The dot matrix on the MILSPEC black ATACR is put on at the unit where as the SOCOM contract scope the dot matrix is included in the rectangle label  and is put on by Nightforce.
I probably explained that wrong so Tiny Crumb or Combat Diver can correct what I messed up. I saw a picture of one of these MILSPEC marked caps last week and wondered what they were on so I asked some guys that would know.

Does the entire reticle tree illuminate on these Milspec marked ATACR’s that are the non SOCOM model people are receiving?

I do not have a milspec marked. I bought one of the socom contract scopes and I have only had time to mount it to my gun. I have not played with it yet.

Well sum'bitch I knew they would but damn I'm impressed!!  I will buy one this summer for sure..............

I don’t think a tan mil-spec has ever been spotted in the wild. Only mil-specs I’ve seen are black and with JSOC SMUs (24th & dev). And those ones have different illumination than civilian atacrs. They may be made at the same facility but they’re not the same exact scope as the civilian ATACR.

So, only plausible guess I have is either a) someone accidentally engraved civilian atacrs with the wrong marking and NF either didn’t notice or didn’t care and sold them to distributors anyway…

Or

NF maybe marks all of their mil-sold ATACRs that way (for reasons like ITAR etc…) and maybe some random mil unit (maybe not even U.S.) bought some that were tan and newer reticles and these are an overrun or cancellation from that order that NF decided to sell to distributors.

Just random guesses. But either way I haven’t seen evidence of any U.S., mil group with tan “mil-spec” ATACRs, and I especially guess we’d never see that in any SOCOM unit given their access to S-VPS.

Thanks,
 I have a second URG-I with a eotech, eyes are getting old and trying to decide between a SIG or another Razor.

I really like the Razor, so guess it will be another Razor when the time comes.

RLTW!

CD does this still stand? No FN Lowers?

A buddy told me he saw some while at range 37 with URGI uppers but i don't know if he was mistaken...

And are black eotechs starting to pop up??

There are very few FN M4A1s in Groups in my experience due to timelines.  I haven't been to Range 37 since 97' when I graduated SFARTAET so can't commit on current weapons there.

I haven't seen any black EoTechs recently

Makes sense, thank you for your reply.

Excuse my ignorance, but do you think SWCS had different purchasing timelines and inventories compared to Groups?

I was digging for FN pictures last night and stumbled across SMA Grinston with a black eotech at range 37 of all places... couldn't find any clear pics of the lowers.

Interesting.

Is there a issued suppressor cover for the RC?

Not that I'm aware of.

Thanks CD. Are you seeing any used? The mirage out of the NF scope is awful on 8x.

Not CD obviously but I've seen a good amount of mod tags being used in photos.

Thank you

Ranger

That Eotech has probably seen some stuff.

Having dealt with both M855A1 offerings from both Sig and Vortex, I would have to say Sig got the contract nod from price alone. There is nothing better about the sig optic in 1-6. Now, as off last fiscal year change, both Vortex and Sigs are ruynning the same price on the NSN website. Maybe that might level things out for them.

I'm thinking the more I see it and where it positions the Razor 1-6 that Whortex should release those mounts because I kinda want one...................

URGIs literally can have any kind of optic on them.

"clone correct' means nothing when anything in the inventory can be found on them

My build list:

Demco mueller dog bone upper 150 (They had the best deal I could find)

450$ DD chf 14.5 Gov barrel

SF4p 180

Geissele SSA-E on sale 200

DDC 13.5 mk16 350

Have a noveske BCG, NFA lower, stock, and the other small bits.

Could have saved you some $$ on the DD barrel at Rooftop Defense.
Sol, owner, is good people and has them in stock with the pinned GB for less, even more less if you join their Hero’s program.

I haven't bought anything yet but when I do I will buy it from them now

Thoroughbred has SF4Ps for $152.  I think free shipping as well.

https://www.thoroughbredarmco.com/product/43/

They have dogbone uppers as well for $145.  Charlie’s has a pretty bad rep for not actually having things in stock.

https://www.thoroughbredarmco.com/product/1030/

Rooftop is where it's at, and Sol is a certified quality human being. Very responsive, and accommodating as heck.

Plus free Ramen with every order.
