SIG 716 PROBLEMS. inspect your rifles.

I purchased a sig 716 earlier on this year. I waited 7 months to receive it. Soon after my purchase i read that sig has obtained a multi million dollar contract with the Gov. I worried that now with this sick high demand has been put on sig. There will be some quality issuance issues. Sigs supply did not meet the demand. So i figured that they would be shipping out guns at a high rate. This rate would effect the quality of the guns.

My sig showed up and i noticed that it did not have the magpul stock and pistol grip on it. My theory on that is. Sig went the more affordable route and put their own stock on the gun so that they can ship out more product.

My sig was damaging the tip of the rounds as it would enter the barrel. picks below. I sent it back to sig and they stated that they fixed the fail to feed issue. I got the rifle back and now its a lot better but it still is damaging the tip of the bullet. Now the gun is going back a second time. I am a sig fan i own 3 sigs and i will continue to buy more. I am upset that this $2500 gun is having issues. Its a 1k yard gun and it should not be at this poor quality.

My suggestion is to feed a round into the chamber and then slowly manual eject the round and inspect the the tip of the bullet.

after the first repair. pics

There are the pics of after the first time they fixed it. .. I emailed sig the pics and they said that the gun should not do that to the round. The asked me to send them back the gun a second time.
The damage is small but i was reassured that it should not happen at all. This will effect accuracy.

I have to think all semi automatic firearms suffer bullet deformation to some degree, the bullet is being slammed in the rear by the bolt and driven up the feed ramp in to the chamber. I don't know if my 716's do it, I don't inspect a round after it chambers, I pull the trigger.
If the gun fires, cycles and groups well, why are you putting yourself thru the hassle of calling, shipping, etc ? Shoot and enjoy your rifle, if it doesn't run properly, get it looked at, by why go looking for problems?

I spoke to sig directly and they viewed the pictures. They said that the gun should not be doing that to the bullet.
you stated. "why go looking for problems.?" I took the gun to the range and i had a crazy hard time siting it in. That's why i inspected it and sent it back. Secondly. This is not a cheap gun. It is a 1,000 yard gun. Will i ever hit that mark. Maybe.
This weapon should be performing flawlessly straight out the factory. I purchase Sigs for the quality and reliability.
Would you buy an expensive car and notice that it has a major problem. Would you return it to the dealer to get it fixed? or Would you just keep it as is?

My Armalite AR-10 does not deform the tips, at half the price! I can easily get sub-moa groups with the right ammo in it and I'm not the best marksman. Sounds like Sig has some work to do, it will never be a 1,000 yard rifle if bullet tips look like that.

Fancy that...My ArmaLite AR10 doesn't do it, either! I shoot mostly exposed lead tipped bullets {Speer 150 grain BTSP} and get no deformation at all.

OP: You are taking the right route. Keep at it, be civil and get the rifle fixed.

Ok, after seeing the pics, mine don't do that. They put a small scratch on bullet down the side. Went looking for a "problem" after finding copper flakes in the chamber after the first few trips to the range. No more copper flakes, after the first few trips.

AR-10 for under $900 new, great deal.

Question, are you sure it's doing this on the way into the chamber and not the way out when you extract it?

I noticed two decent scratches on my spent casings and the same scratches on the bullets of rounds I had chambered but had not fired and manually eje.
I did that before i shipped the rifle back. I have chambered and extracted the bullet several times and many different ways. The first time i sent the gun back i chambered and checked 40 rounds. All of them was damaged. 40 dollars down the drain. When i received the gun back i checked and inspected 5 rounds and it caused minor damage. Pics posted above. Like i posted before. Sig Sauer stated that it is not suppose to do that at all to the bullet.
My guess is sig is mass producing too many 716. There quality control is suffering because of it.

I fired my 716 for the first time last weekend and I had the jamming issue that many others have seemed to have problems with. Out of the 100 rounds I shot, probably close to 40 of them jammed. I had to use a rubber mallet and lightly tap on the charging handle to get it unstuck. Inspecting the round I noticed scuff marks on the casing like the round was slightly to big to fit into the chamber. I only had one brand of ammo so I couldn't try others, but I know many others have had issues with this. Very frustrating day to say the least. Sometimes I had to try 4 or 5 times to get the first round to even load correctly.

Try to find a dealer that would allow you to return it to them directly in the event of failures.

If you get one that works, it's perfect.

I can't deny that there seems to be a bunch of lemons in circulation out there, however.

You are not alone! I took my brand new Sig 716 to the range today. I have the same issues. After having to hammer the bolt open several times in 42 rounds I quit. I found gouges in the fired brass and unfired chambered rounds.
I'm calling Sig Monday. I hope they have good customer service.
And thanks for the post it helped me fiqure out what was wrong with mine.

I fired my 716 for the first time on Friday, only 20 rounds though. The round did not chamber, and felt stuck. Rather than forward assist, I removed the mag and pulled back hard. The round came out.

I tried again, but this time I locked the bolt back, and replaced the mag.. I released the bolt and it chambered and fired well. I loaded 4 rounds each time and repeated five times with no further incedent.

I am hoping this is a result of a weapon designed and built with very tight tolerances, and that breaking in will result in a fine system.

I do think it is important to disasemble the bolt group to remove the high viscocity factory oil. when reassembling the bolt, make sure it is wet going back into the bolt carrier. It may not hurt to a little extra sheen on the entire bolt.

If I can find some cheaper ammo, I will do another test run in the next week or so.

Aside from all this, the gun felt smooth to shoot considering the caliber

I posted earlier and my brand new SIG 716 was awesome using 60 rds of PMC Bronze & 40 rds of Federal Eagle. Some guy from BigDaddyGuns in Florida sold me on some cheap Aguilla. Set em side by side & they even looked like ****. I pulled em out of the box & noticed black sticky residue all over the rds. Wiped every one off, went to the range & the gun fired 40 rounds flawlessly. While at the range, I took another 20 rds. of Aguilla out of box, DID NOT wipe them down & the gun wouldn't stop jamming. So bad the hammer was locked up & we had to pull the gun apart to remove one of the jammed rounds. The casings that were once flying 5 feet over my shoulder were now dropping on my table and getting stuck in the window. About 6 or 7 times I had to pull the hammer back, turn the gun over and shake the casings out. Frustrating to say the least, but I loaded my last 10 rds. of PMC and she cycled flawlessly. The casings were still dropping on the table so I'm a little concerned. Waiting for 500 rds. of Federal Lake City to come in this week. Will update later.

What kind/weight of bullets are those? Is the over-all length of the cartridge a bit too long? The tips of the bullets in the magazine are probably sustaining that much damage by the time they cycle-up, chambered and fired. From my experience, the tip of the bullet can have a little deformity and as long as the base/core of the bullet is still intact and balanced, the bullets group just as well.

I also have a 716. I have not fired mine yet due to the -12deg weather we are having.
Yup I'm a wuss.
I did see a guy on you tube I do not remember his name.
He had a brand new rifle and had to tap the bolt open with a rubber hammer.
He took it completely apart and cleaned all the oil out and reoiled and the rifle worker fine after that.

Agree completely. This is why people pay a premium for Sig.

Given modern machining capability, if tolerances are met the rifle should work out of the box.

If Sig has grown significantly, they could experience a variety of problems leading to quality issues. But hopefully they are managing their growth successfully.

After handling several other AR10 platforms I am going to make a prediction; Sig will offer a stronger buffer spring. I strongly feel the extra spring weight would eliminate many of the "out of the box" problems people are having.

Will take mine to the range again after a good cleaning and see what happens.The last time it would not feed evey few rounds after the initial 60 I fired without any problems since then a royal pain in th ***.The rounds that did feed were very accurate. Hopefully after a few more rounds it will function like it is supposed to but based on my short time with it would I buy another SIG NO.I have a Black Rain and from the first round out of the box has worked without any problems maybe SIG should find out what they are doing riight but will admit one is piston operated where the other is not.
