Review: Sig 556R - Not what I expected

Great Troubleshooting

Pun Intended. I just purchased a Sig Sauer 556R... unfortunately before your outstanding review. You did an outstanding job of considering external causes and eliminating them. I am very disappointed that Sig Sauer still produces this model with this problem 4 1/2 years after you brought the failure to fire issue to the public's attention. My rifle shot maybe... 15 rounds... before it stopped firing. My gunsmith is trying to resolve the issue and suspects a spring defect.

My YouTube response suggests that Sig Sauer should do the proper thing and issue a recall to address the failure to fire issue. This is a potentially life threatening condition, because rounds also stick in the barrel. The good folks at Gander Mountain in Tyler were surprised the barrel did not explode. Hopefully Sig Sauer is not waiting for an injury or death to seriously assess and address the failure to fire and stuck cartridge issues.
 
My take is if you want an AK, get an AK or an XCR.

Yep, RA has issues, but the gun is a true inheritor of the AK traction that's truly modernized, but keeps the simplicity of the gun.

I own both, XCR is as solid as the AK with far better layout as well as controls that are world class (no one has matched them yet, some have picked off one feature or the other).

"Second, I change the trigger system to a national match two stage trigger, I like Bushmasters set up."

You are way off there. The Bushmaster two stage was the weakest hammer spring you can find in a NM 3 stage trigger. That damn sure is not going to help your problem with misfires.
 
steel cased ammo/cheap ammo, whatever. for the price of this thing it had better feed and fire reliably anything you feed it. period.

I won't buy any new Sig products, as much as I love their 220/226/229. They're both overpriced and overhyped. I'll buy old used West German guns and give my retail business on new guns to a company more deserving of it.

I am wondering since Sig Sauer did a rework of this rifle model if you are going to take another look. And also what do you think about polyformance 7.62x39 ammo.
 
I am a range officer at a large public range in south Florida.
I see all sorts of AR problems. Usually with new rifles, rifles dry of lubricant, rifles with el cheapo magazines, rifles using weak gun show reloads AND rifles using steel cased ammo.
What I have seen is that if an AR will work with steel cased ammo, it will work with anything.
The usual problem is failure to extract, case stuck in the chamber. Generally after a few rounds have been fired allowing the rounds coating to stick to the chamber walls.
a thorough cleaning and then polishing the chamber with Flitz does help a lot to solve the case sticking problem.
As far as Sig rifles being a problem, no more than any other brand, no better no worse.

The main problem is there aren't enough non-AK 7.62x39 rifles on the market.

SKS? :D I love mine (non- modified Norinco Para)

Yes, I would also like to see more "non - AK" rifles that shoot this round. Shame to hear that the SIG Sauer is such a disappointment... Always wondered about the Rock River LAR-47.... :confused:
 
I have one of the newer generation 556R's and it has been flawless. The red dot sight they give you is crap, but the rifle itself has been totally reliable. I have only shot Silver Bear through it. Look for a gun that was made in July, 2012, or later and you should be fine.
 
Sturmgewehre: I've enjoyed watching a bunch of your videos, and only watch about five Youtube Channels (all guns) on a regular basis.

Maybe you are fortunate that you either got your money back, or have credit towards another purchase at the store (?).

Having seen your major problems with the Century Tantal AK-74 (shooting 5.45 thorough a 5.56 bore...which Century certainly Knew about when they were sold...) and very lucky 'service' with Century, hope you did ok when this Sig was returned.
