| I thoroughly enjoyed my first time shooting an AR yesterday. I bought a case of Wolf Gold and my bolt never locked back on the last round of my PMAG mags. I was told that Wolf tends to be underpowered. Anyone else have problems with this? I'd prefer this over an undergassed system. |

Let your rifle" break in" a little more before you start changing parts. Wolf Gold 55gr is a far ( better ) cry from typical Steel cased Wolf.... so don't worry to much yet. What specific rifle and buffer weight ? |

I'm not too sure but I think mil spec. RRA lower w/2 stage trigger. I'm not sure how many rounds BCM put into it but I have around 120 rounds through it. I shot it for the first time Saturday. BCG is BCM. Would an H2 be GTG if need be?
Upper is a 16 inch middy w/Troy rail from BCM. |

Did you give the rifle a good cleaning when you brought it home? That sticky grease / preservative needs to be removed. Then lube what needs to be lubed.
Look here for a good guide on what to lube and how much: AR lube points eta.. Wolf Gold is very good ammo. Not underpowered by any means. I suspect a good cleaning and lube will solve your issue. And keep those lube points lubed. It's called keeping it "wet". Not to excess, you will quickly find out the line between just enough and too much!

There's a big difference between the old "this stuff is weak" Wolf steel cased ammo and Wolf Gold. Wolf's old "black box" steel cased stuff was made for them by Tula, whose own ammo is regarded as "underpowered." It's not really, it's just not tuned to play well with ARs, and so it "looks" wimpy. Wolf Gold brass cased ammunition is made in Taiwan, and is high quality stuff. It's in the same class as M193, just a little cooler. As someone else said, your new rifle is probably just not fully broken in. The BEST practice is to strip a new gun, clean the preservative coatings off the parts, and then thoroughly lube it up before hitting the range. It makes a difference. Keep the gun thoroughly lubricated and use quality, full-power ammunition, and you'll soon see a difference in how it runs. |

An H2 buffer is heavier and a heavier buffer is typically used when a gun is over-gassed, yours sounds undergassed , or more likely, sluggish from being brand new and tight..... so no stay with your OEM one for now. And plus 1 on the cleaning and good oiling. My first BCM upper was "tight" ( a good thing ) with a little breaking in and good oiling ( not just the way it came from BCM ) it now runs like a champ. |

It looks like a careful reading of the issue is that the bolt is not locking back on the last shot of a mag?
. Perhaps the mag or catch? Quoted:

I'm considering trying another brand of ammo in hopes of confirming Wolf Gold is the culprit instead of a gas issue. I currently use Wolf Gold .223 55 grain. Any suggestions on what other brand/grain to use? Try some plain 'ole Federal XM193... if you rifle coughs with that ( after you have cleaned and lubed it and allowed for a "Break-in" period )..... then you need to look further down the AR15 rabbit hole. |

If I put an empty PMAG in and open the bolt the bolt will lock open. Not sure if that would make a difference. That demonstrates that the magazine and bolt catch operate, not that the gun can make that happen with the ammunition you're using. The amount of effort you put into opening the bolt is not something you can equate to the amount of energy the gas system imparts to the carrier. Your body automatically applies more force until your objective is met, so it's really difficult to "by feel" compare whether or not you're putting the same amount of energy into the charging handle from one cycle to another. It may only take just a tiny bit more energy than the carrier is getting from the gas system to get past the bolt catch enough for it to operate. Again, get to basics and start with a very clean, properly lubricated rifle. See whether the gun will lock back after five rounds in a magazine. Try different magazines too. Until the gun is thoroughly broken in, you may see weird and intermittent issues like this, which could be simply due to tight bolt rings and the gas block and gas key becoming thoroughly sealed. There's no guarantee a new carrier's key is gas-tight, nor that a gas block is gas tight to a barrel. It can take several dozen rounds to build up enough soot in the junction between the key and the carrier for it to seal, and though the gas block should take fewer rounds, if both are a little leaky, you'll have less power to the carrier and it'll take longer for both to seal. |

First time I tried WG the bolt did not lock back. So I tried American Eagle w/the same PMAGs and the bolt did lock back. Next time out I go back to Wolf Gold w/same PMAGs and the bolt did lock back after the last round of the mag. Cleaned and lubed rifle after every range trip.
What the heck is going on? |
