Navy SEAL's Thoughts On The New SIG SAUER XM5 Rifle

Retired Navy SEAL, Mark “Coch” Cochiolo, shares his thoughts on the new SIG SAUER XM5 rifle.

The SIG XM5 is the U.S. Army variant of the SIG MCX Spear, a 6.8×51mm (.277 in), gas-operated, magazine-fed, assault rifle designed by SIG Sauer for the Next Generation Squad Weapon Program in 2022 to replace the M4 carbine.

As usual, Coch is level headed and practical in his analysis. Great job,

[cameronfelkel]

I work at FN America and love my job and what I do. The only thing I had a problem was when they put a gun system in the hat for the replacement. They put the SCAR HAMMER, and that's like a 20 year old system and I knew they would not get picked. But we still make damn good weapons! And that's good enough for me! Love the break down!

When I went back in time to 1914 and briefed General Pershing and the War Department on this new thousand yard rifle he and they were very pleased.

This is one of the few takes that understands this new system. M4s aren’t gonna get retired. They will still have their use mission dependent. The M5 brings back the battle rifle capability. More important new systems imo are the new light machine gun and sniper rifles.

I've been told troops will train with low pressure rounds and fight with high pressure rounds. I hope not. I remember the lecture we received about the infamous Newhall shootout that left four California Highway Patrol officers dead. It was partly blamed on their training, which included the use of low pressure 38 Special loads on the range and high pressure 357 Magnum loads in a real gunfight.

We predated the British EM2 280 with the Garand in .276 Pederson but MacArthur nixed that because of all the 30/06 Ammunition left over from WWI. The British also had a .276 cartridge even earlier this one in their Pattern 1913 Enfield with ballistics similar to the 7x57 Mauser and now we are back to the future with a 277 caliber rifle which I think is great

"Tack hammer, framing hammer, and sledge hammer."

I wish the generals and admirals could grasp this concept.

This guy is awesome. So down to earth, and shares some great thoughts and experiences. Well done 👍

[StreakedSilver]

Very interesting to hear feed back from someone who got a hell of a lot more training than the usual line grunt or Three gunner.

Your feed back is amazing and frankly is helping me check myself in how I portray some things in a project I am working on.

I can see the XM5 Spear filling a niche, as a platoon "heavy hitter", a sniper support weapon (spotters rifle with an LPOV), and a SASS replacement/supplement.

Weapons R&D Mil Contractor here:
I was relieved to hear your opinion! I had this take when NGSW closed because I was familiar with the MCX Rattler getting favorable reviews in combat. My personal take is that it will be a family of firearms (MCX Rattler using .300 blk, M5 and M250 using 6.8, MG 338 using .338 Norma Mag [I get it, only two in that ‘family’ are MCX, but keep reading]) but also a family of cartridges. There is a distinct design effort put into the M5 and M250 that gives them function at a range of chamber pressures. The 6.8 hybrid is not just an 80k bullet- it can be loaded from 60k to 120k psi. It would make sense to have the 60-80k carts primarily for the M5 and the 80-120k carts for the M250. This would only be a problem if either weapon would malfunction under adverse chamber pressures, but both are designed to function normally from 60-120k psi, so in a pinch you can throw the LMG rounds into your battle rifle and vice versa. More evidenced by the implementation of the M157 fire control package that will issue with both of these systems.

I got to shoot the XM-5 at the SIG event in Phoenix. Very impressive. Un-zeroed, I was hitting steel out to 600yd, with a pretty heavy crosswind. Less recoil than my AR-10, very quick to re-acquire a target. I just wish they had the new optic, XM-157.

[andrewsteele]

Thanks Coch, always enjoy the way you deliver the info, here in OZ we are still on the 5.56 wagon. But I wouldn't be surprised to hear that our SF chaps are using it, cheers

[BRoweofKY]

I always look forward to the videos from Coch. His years of experience shine through and he presents his thoughts on things quite well. But this time I was derailed… what a WATCH COLLECTION🙌🏼

[ftdefiance]

In my opinion the Army needs more than one rifle. Fighting ridgeline to ridgeline in Korea this makes sense urban combat perhaps the AR makes more sense.

[madmaxd]

First off... Thank you for your service.
I like when our military makes technological advances. Bringing new platforms with new cartridges is definitely going to have barriers for success. Let's hope it doesn’t go to waste...
Thanks for your perception on this topic..

I did my military service using 7.62x51. They were deadly to carry. In a contact situation however, that bullet went right through trees making "cover" more difficult to find. When we moved to 5.56, it was great to carry more ammo but the hitting power was always viewed as "iffy" by the old school. A modern 6.8 is probably the best compromise particularly with the higher chamber pressures achievable these days. Whether the Sig is the weapon, I dont know. I think the power rail could be significantly redesigned to make it less bulky. What I do like is that it is not a bullpup as the magazine changes when you are flattened as low as you can go with rounds overhead, I guess I just grew up getting to absolutely love the FN style 7.62

Randomly recommended video on my timeline. I subscribed because I like the humbleness and simplicity of how he describes the topic of the video. No shots given but School teachers/College professors or anyone in a leadership kind of position please take note on how he explains. I think there’s lots of value to be learned. This is the kind of person that can explain tensorflow to a kid in first grade. Thank you sir!

When I was going through gunsmithing school one of my master smiths pointed out we haven't really had any leaps in firearms technology for awhile. In terms of operating systems we haven't really seen anything majorly new for about a century till recently. (I think the Lago Alien counts as something new, even if it's using similar principles as what came before. There's some other interesting recent innovation too, but that's very recent and this was 2014.) Where we've seen innovation in terms of bang sticks specifically has been material. The WWSD rifle's probably an ideal embodiment of just what we can do with modern material sciences that simple wasn't possible 50 odd... or even 10 or 20 odd! Years ago. The other place our class determined we'd see a lot of innovation besides manufacturing techniques, was ammunition. Sig's new round, the 7.5 FK BRNO round, and numerous others appear to be proving that little bit of noodling and discussion out.

I really enjoyed your well articulated yet soft spoken and deeply knowledgeable analysis. Family friendly so even my kids could watch.
