I'm just a guy who enjoys shooting and training, I've never been in the military. That said, this Sig rifle seems to miss the mark on so many obvious levels.
Not to mention the very significant increase in weight and reduced ammunition both in the rifle and in the soldier's loadout, the other problems are equally glaring to me.
This rifle is touted as having increased range, but every test I've seen shows that it is significantly less precise than some of the more modern M4 derivatives such as the URGI and even the block 2.
What good is having a hot rod cartridge if it is shooting 4 MOA? The poor accuracy more than offsets the increased effective range. It kind of makes the Uber expensive Vortex optic a waste as well.
If I was running the ship and I insisted on a cartridge with greater range, the 6 ARC or 6 Max seems like the obvious solution. Same small frame AR platform, same manual of arms, not much more recoil, not giving up much in terms of magazine capacity, and a significant increase in effective range.
Personally, a Geissele URGI with 77 grain mk262 and a Vortex Razor 1-6 or Nightforce NX8 1-8x would be my choice as the standard service weapon and ammunition.
But again, I'm just some guy in the woods who likes to shoot.
I'd be willing to bet my house that someone at the DOD is personally benefiting from the decision switch to that POS rifle.
