As far as I am concerned, SIG USA is a company that just doesn't get it. Since they don't get it now, they probably never will.

However, this is something of a step in the right direction, but we still have the garbage pot metal sights that are the wrong height for the SIG 55x platform, the flash hider is balls, the rail is the same crap as the 556, and the hand guard is all wrong.

I don't especially have a problem with the aluminum lower...for now, but the magazine paddle doesn't look as easy to access as the Swiss model

I've got time. I'll continue to wait for something built closer to the true Swiss TDP

I'm not a fan of how the newer stock looks (the side-folding/collapseable one) and am glad they stuck with the older design.

I'm a fan of the paddle release as well.

i wonder if you could use the sig 55x (not 556) parts on it, i'd be in for a 552

A few of these have popped up on gunbroker.

It still looks like SIG USA doing SIG USA nonsense.

Is it really that hard to add sights actually made for the gun, and a proper Swiss spec handguard?

If nothing else, for your DIY project lovers, this gets you a few steps closer in your efforts

Id only need a few minutes with the girl and she would be prancin around with my acr.......and that smile....but with a slight limp

 

[SDDuc996]

Why in the hell would you kick her in the leg?

 

[Rombot]

Military Arms Channel did a review on the SIG556R and basically said the same thing... his 12 minute video was at least 5 minutes about how it fit together bad and how badly it FTF.

 

[SperlingPE]

girl - keep the rifle

Why in the hell would you kick her in the leg?

Yeah, I purchased a SIG556 Classic last year. It was not money well spent. The SIG556-A1 is just more of the same cost cutting/bean counter/make as much as we can until they wise up, crap! SIG USA got this rifle all wrong too. After looking into swapping out the aluminum lower for an imported Swiss steel lower, I decided it simply wasn't worth the time and money. The original SIG 550 series rifles are selling for about 4K. I sold my 556 and my matching 522 training rifle and bought the ACR. The modular feature of the ACR sold me. Once the aftermarket and Bushmaster or Remington catches up, it will be a great platform. Hopefully this works out and I don't lose my butt like I did on the 556 and 522. Live and learn!
