Sig 716 Problem

First of all I'm not the idiot on youtube that posted 12 videos of himself whining about sig. I'm new to these forums and I'm sorry if I posted this in the wrong place or if this issue has been covered elsewhere.

Now then, I purchased a new Sig 716 yesterday with several boxes of ammo. All the ammo was expensive, brass cased ammo. I got home and broke the rifle down completely and did a extensive cleaning on the gun. Once it was complete I loaded up a mag with 5 rounds and put in the mag well with the bolt locked to the rear, I released the bolt and it went forward and chambered a round but it sounded VERY sloppy instead of slamming a round home into the chamber. In fact it didn't even fully go into battery... it almost did but it lacked about a quarter of an inch from being all the way. I then tried to manually eject a round and the bolt was completely locked/jammed into place and wouldnt move. I tried using the forward assist and put it all the way into battery but it was still locked into place and wouldn't move. I had to get a screwdriver and pry the bolt open to get the round out.

There is a guy named Spyke on youtube who was having the exact same problem as me, identical. However when he broke his rifle down and cleaned it the problem was eliminated and his rifle would manually cycle fine. Cleaning didn't do a damn thing for me.

So I tried it for the third time and of course the bolt was locked shut again. I am getting pretty ****** at this point. I throw on my hearing protection and go outside, point downrange and fire. Of course the bolt opens and ejects the case fine and locks to the rear. I then loaded up 4 more rounds into the mag, dropped the bolt and as always it sounded sloppy and weak and didn't go all the way into battery. I used the forward assist to move it up that tiny quarter inch into batter and took the safety off and squeezed the trigger putting all four rounds downrange without a single problem with the bolt locking to the rear on the last shot. The gun shot absolutely fine. I then tried a final time to manually cycle rounds and to no avail it still wouldn't and I had to pry it open again.

Can anyone please help? I love this gun and I worked very hard and paid $2100 (tax and all) for it. I really want it to perform flawless. Had anyone had this problem before? Any remedies? Any tips? Thanks in advance and sorry this was so long winded.

This is Sad, I was on the fence between a 716 and a 17s, since I already own a 16s I'm guessing you guys just made the decision for me. I guess thanks, I'll just stick to Sig for my pistols.

Same here, for now. I had my heart set on either a 716 or a 556 but, I think right now is a good time to just let Sig get the bugs worked out. Knowing Sig, they will definitely get it done. Too many professionals rely on their products for them to do nothing. I vaguely remember when the P229 first arrived on the scene back in the early 90's(?). It was buggy as hell - didn't like anything it was fed and the barrels were made with the wrong twist in the rifling to stabilize the .40 S&W projectile for decent accuracy. It only took Sig a month or two to get those problems squared away. I bought a P229 about 6 months after all that and it's one of my favorite pistols - accurate, reliable, comfortable to shoot even with full house loads. I suspect their rifles will be no different.

I have a Sig 556 and a 566R, and they are great rifles. They are accurate and function flawlessly, it is a shame that the same can't be said for the 716. I have more Sig pistols than my wife will ever know about and I love them. They not only look good, but they are accurate and very reliable.

Sig has been pretty good resolving 716 issues. I have a gen 2 w over 1000 rounds through it. No complaints. Sig will test fire it before it comes back, make sure to ask em what ammo was used. W the piston guns, make sure it's lubed where it needs to be and make sure the gas ports are clean and line up properly. I've got a Adams arms cor I paid some moolah for and it won't run Tula ammo.... For what I paid for it I would expect to run a cat turd with a primer in it through that thing but it won't work. Polished chamber n all. Hang in there they'll get it right for you...

IMO, and I'm sad to say this, the 716 is an acceptable rifle for a sportsman... but not a "go-to" rifle for someone that's going to depend on it. Too many of us have had issues, some even after SIG servicing.

I can tolerate the occasional FTF at the bench. Whole different ballgame if I actually had to count on my rifle...

This is the letter I sent along with my 716 when it went back for repairs.

Dear SIG,

This 716 has feeding problems. The feed ramp is not raising the round high enough to enter the chamber properly. Instead, the tip of the bullet is striking the face of the breach just below the radius at the mouth of the chamber. As a result, the bullet is deformed and causes bad accuracy. Typically 4-6 MOA. If you close the bolt slowly with the cocking handle the round will hang and stop the BCG. It appears that the bolt head lug cut-outs, centered in the feed ramps of the barrel extension, are spaced so that the diameter of the bullets ogive, when passing through the notch rides too low to elevate the round cleanly into the chamber. If the ramp was back from the breach a bit, (not milled as deep) the increased angle would probably cure the problem. Even if a more obtuse ramp angle were needed to accomplish this geometry.

Not to be cynical, but a ramp/chamber polish is not going to fix this problem. And please don’t advise me that the gun is “ammo sensitive.” If it can’t chamber a FMJ round I have no use for it.

I was at the range this week and another 716 owner was testing his rifle after it had just been from for service for the second time. His gun would not feed at all. We swapped magazines and three different kinds of ammo back and forth. It made no difference. His gun jammed bullet tips into the breach face instead of the chamber just like mine. So this can’t be too isolated of a problem with the 716. I have a SIG 556 that feeds perfectly. I also have nine SIG pistols that are all great handguns. I’ve always been a big fan of SIG’s guns. I hope this rifle can be made to function properly.


The gun was returned today. I had to take half a day off from work to sign for the delivery, as Fedex will only deliver to the home address for security reasons.

My hopes were high that the problem had been resolved. Then I looked at the test target that accompanied the rifle. It was a two plus inch group, shot at 25 yards. That’s 8 MOA.

So I figured well, maybe their skilled gunsmiths are just REALLY bad shots. So I took a round of my Lake City .308 FMJ and put it in the magazine. I held onto the cocking handle and slowly allowed the bolt to start closing. As soon as the bullet’s tip touched the breech face, below the chamber mouth, the bolt stopped. This once again was exactly the problem I needed fixed. I looked at the repair order Sig sent back with the gun. It said, “Polished feed ramps, cleaned and lubricated.” I looked at the breach face. It had two areas directly above the ramps that were smeared with copper jacketing. So in other words, Sig fixed NOTHING before returning this $2,000 piece of garbage rifle.
I called the customer service phone number. The guy seemed apologetic. When I asked why they had ignored the letter I’d sent with the rifle, I was told that he didn’t know. That he didn’t really talk with the guys that work on the guns. I told him that if they couldn’t fix the problem, I didn’t want the gun. That I wanted a refund. He said they don’t give refunds, that I would have to send the rifle back to them so they could work on it again.

If I didn’t have a conscience, I would sell this 716 in a heartbeat. However, I would feel awful knowing that I had screwed a fellow shooter by passing along this worthless piece of garbage.

I have to say I've been reading the posts on the 716 problems and was a little worried. I have had one on layaway for a while and picked it up today. I did break It down and make sure everything was in it place but I didn't clean it. I though I would see how it ran out of the box. Filled 3 promags with 3 different Ammo's. It ran all three and never missed a lick.
I'm breathing a little easier now. I realize its not a major test. I will give a thorough cleaning now and see what kind of groups it gets.
BTW: mine was made 11/13

I bought the DMR It took over 6 mo to get it, Ordered in Jan got it in July. I cleaned it twice. Lubed it up and it shoots anything I feed it. Cleaned it Lightly oiled it and had a FTF and a FTE, Opened it up added more Break Free lube to it and it ran everything I fed it. Have allways cleaned and used high speed axle grease on the parts that show wear and lubed the rest and have never ever had a problem with it. Not much grease just apply with the end of a tooth pick. I totally love this rifle, Ive had several shoot off's with other friends my rifle has never jammed or failed to perform flawlessly. Every one who shoots it just says WOW what a rifle. Sig is #1 in my book.

Several months ago I and my friends and cousin all bought sig716s on black friday. Long story short my friend took his shooting and came back his bolt was seized and the FA seemed like it was stuck in the depressed position. I carefully took it apart only to find his rifle damaged. Scored on the inside of the receiver and two broken FA parts. This rifle has maybe 100-200 rounds through it. Diassapointing to say the least. The same friend has a sig 1911 "nightmare" compact model. And first time shooting that his rear sight came off he sent it to sig they "fixed" it only for it to happen again 1 50rd box later. They ultimately replaced his.whole slide. I love sig have many signs in my safe I'm beginning to second guess their products though. P.S.I have pictures of what found in his rifle

You literally just registered now, and in your very first post revived a nearly six year old thread, to troll on Sig at a Sig forum.

It's obvious you have an agenda, and what you say about Sig absolutely applies to all other major gun manufacturers!
