Remember the U.S. Army’s Next Generation Squad Weapon, AKA the XM-5, AKA the XM-7, AKA 6.8 x 51mm? Brandon Herrera has managed to get Sig Saur to send him the prototype of the new weapon (the Sig Spear) to test, and…he has some reservations.
The caveat here is that this is not an actual 6.8 x 51mm XM-7, it’s chambered in 308 Winchester/7.62 x 51mm (two calibers that are extremely close but not exactly the same), so the ballistics and operation are likely to be slightly different. (To make matters worse, the civilian version of the round is being marketed as 277 Fury. As far as I can tell from looking at Gunbroker, 277 Fury ammunition is available now, but models of the Sig Sauer MCX Spear chambered for the round aren’t yet on the civilian market.)
Pros:
Short stroke piston doesn’t need a buffer tube, meaning that the gun can have a folding stock. “Actually pretty cool.”
Decent trigger.
“This little right side bolt release here. Kind of a fan. Feels a little flimsy, but I like the placement.”
Left side fold-out charging handle is good.
“Hand guard here offers a lot of space to mount whatever shit you want.”
Two gas settings.
Silencer works (even if not hearing-safe quality).
Likes the flat dark earth (FDE) finish. “In my opinion, it’s a pretty sweet looking gun.”
“Gun recoil impulse not bad.”
“Running it suppressed it’s not that gassy.”
Very reliable, at least over the initial 200 rounds.
The cons:
“It’s fucking heavy, dude!…Unloaded it comes in at 8.9 pounds. For reference that is one full pound, or 13% heavier, than a full-size SCAR 17, which is also a semi-automatic 308 with a 20 round magazine.”
Folding aside, the stock isn’t great and wants to slip.
“This charging handle in the back is borderline fucking unusable. It feels, really flimsy, like I feel like I’m gonna fucking break it. And it’s stiff. It is so
fucking stiff! ‘How stiff is it, Brandon?’ Joe Biden in a room full of school kids.”
Potentially the biggest combat problem: Overinsertion of the magazine. “If you put too much force on the magazine when you’re inserting it, you will actually run up past the magazine release and get the weapon jammed.” Yeah, that sounds like a huge problem, and Sig needs to get that fixed ASAP.
The spring is a bit hard to get back in.
Super expensive right now.
From the comments on the video: “The fact that he’s actually able to unironically hold up a Scar 17 as a lighter, more affordable option is just batshit insane.”
Yeah, looks like Sig needs some more work here before it’s ready to field…
In a previous post, I made the assumption that the army’s decision to go with 6.8 x 51mm for its Next Generation Squad Weapons (NGSW) program meant they had selected the True Velocity 6.8 x 51mm TVCM round.
That appears not to be the case:
About 3:40 in, he says the army choose not to go with the bullpup and it’s polymer ammo, so presumably TVCM is out of the picture for now. Instead the new round will use bimetallic steel-brass hybrid ammunition manufactured Remington. On the other hand, he says the “Lake City Ammo Plant” is in Utah, when it’s actually in Independence, Missouri, so some grains of salt are in order.
