I bought an AR556 a little over a week ago. When I was sighting it in I noticed the bolt would not lock back on an Empty mag. Once sighted in I started to shoot it in earnest but it had multiple cycle issues. It would always eject the spent round but sometimes it would fail to pick up a fresh one and would close on an empty chamber. Most of the time it would jam with a round caught diagonally. The more I shot it (or tried to shoot it) the more problems it had. To me it seemed to be a gas problem with the bolt not cycling all the way to the rear. Well the problem turned out to be the gas key was not tight. Mine had the "fake" stake like the one in the OP's pic. Once the key was snugged and properly staked it has functioned perfectly as it should.

I'm not a Ruger apologist, however, it is true that Ruger is trying to make a rifle with a lot of value here. Just as with the SR1911, you get an American made gun with most of the features people are looking for that's priced lower than the less well equipped competition.

Clearly, this requires figuring out how to keep manufacturing costs down. I suspect the gas keys may be staked by a machine, and that perhaps it's tricky to calibrate it to be just right, as opposed to either too light, or driving the punch right through the bolt.

The alternatives would be hand staking done by a highly skilled worker, or hand staking done by a non-skilled worker. The former would give the best results, but would cost too much. The latter route would be affordable, but would yield very inconsistent results.

While it certainly would be nice if all AR-556 rifles were staked well, Ruger probably can't attain that without it costing more. Fortunately, the fix for this is not hard. A moderately handy person can do it themselves. If not, it's a very easy thing for a gunsmith to do.

looks like using a machine or an (unskilled worker) gets the same results......the machine that may be doing this obviously costs a lot of money and maybe there is an (unskilled worker) setting it up to do the staking....and yet another ( unskilled worker ) doing the QC on these which sends out poor rifles to be fixed later....whole thing kinda looks ( unskilled ) ??

While the gas key screws SHOULD be staked properly by the manufacturer, many of them AREN'T. Same goes for the castle nut holding the buffer tube onto the receiver. Just takes a good whack with a punch to have piece of mind that they aren't gonna loosen on you. For something majorly wrong with a new rifle, sent it back. Gas key screws and castle nut screws not being properly staked are not a major deal that can't be fixed to your liking.
Besides, if the factory doesn't deem proper staking important when your new gun left the factory, they are not gonna think it's that important when you send it back to them and complain about it. It might come back to you no better than when you sent it to them.
This is a weapon that you might be using for self defense, patrol duty, or S.H.T.F. Don't take anything for granted, and inspect every new weapon thoroughly.
A lot of otherwise good AR's are being sent out without the gas keys or castle nut being properly staked, or even staked at all. If you don't feel comfortable staking your own, get a knowledgeable friend to help you.
AR's are like 1911's, everyone should have some knowledge of basic repairs and have some basic tools. You might need to change out an extractor, firing pin, etc. someday, and not have the option of leaving it at a gunsmith for weeks or months, or sending it back to the factory and being without it for a while.
These days everyone on the internet is an "AR expert". You are going to get a lot of conflicting opinions and end up thoroughly confused. Buy or borrow Patrick Sweeney's "Book of the AR". He has five of them out on just the AR, although the first one is the most informative as far as maintenance, disassembly, proper ammo, optics, etc.
I believe he studied engineering and metallurgy in college, was a custom gunsmith for many years, a competition shooter, and teaches law enforcement groups in his home state of Michigan. He also has put out books on gunsmithing, the AK and SKS, Glocks, and several books on the 1911.

looks ok as long as the bolts don't move. Use a Allen key and see if you can move the bolts if they don't move your ok here a pic on mine I had the same concern. But I think my is staked a little more then yours

Notice "YFS" is on the bolts. YFS are cheap bolts made in Taiwan. So on top of not being properly staked they use cheap screws. Bolt is also made of 9310 steel, which is more brittle and will brake, unlike the proper mil-spec steel which is 158 Carpenter. Sorry but Ruger makes a HORRIBLE AR-15.

My AR556 gas key looked pretty similar to the one in the OP's picture. I "properly" staked it myself with a hammer and punch with the help of a vice. Pretty simple task. I haven't had any issues with the rifle, however I only have around 200 rounds through it. If you're not comfortable staking it yourself I'm sure if you have a gun shop/range close by they'd do it for free or next to nothing.

Been reading a lot concerning AR556 BCG, I'm a new AR556 owner. If I decide to replace the BCG, what brands are advisable and will fit in the Ruger? Should it be 158 carpenter steel I read where 9310 was enhanced steel? fully shrouded firing pin?, Need to be MP magnetic particle tested? HP high pressure tested? shot Peened? What about cost? Thanks much, Boatman

Shoot the crap out of the one you have after you've verified the gas key fasteners are tight and properly staked. If you decide to go with a new BCG there is an abundance of choices out there, stick with a Full auto/milspec BCG from a respected manufacturer.

I would send Ruger those pictures just to let them know it got out that way.
Then I would take a punch and re-stake it to my satisfaction.
Problem Solved and no waiting around for it.

Any mil spec bolt or carrier will fit and function properly in the Ruger AR556. I put a DSArms full auto bolt carrier group in mine because i wanted a shrouded firing pin. It works perfect.
Do your own research and decide for yourself.
