I think only girls should WIGGLE.....LOL
No really, I think the wiggle room would allow gas to escape and may cause extraction issues.... |

Looks like gas block is out of spec. I put the new gas block after removing the original.

And considering the gas tube is the cheaper part, and easier to replace I'd try that first. ETA: it should not 'wiggle' around in the gas block, but you might get a bit at the receiver end. Some gas blow out is normal (you'll see black marks) eventually - if the rifle is functioning right - that will decrease as carbon slowly blocks the gaps. Try it at dusk, if you see flash comming from the gas hole when you shoot, or you're having functioning issues then you need to address it. |

picture?
if a tube leaks slightly. its going to fill with carbon in a short time. but if your short stroking and your tube has a 4" black mark on the outside something is up |

If the wolf is causing it to short stroke, it's a problem...maybe. What sort of rifle is this? If it's a 14.5" barrel with a mid length gas system and your running a heavy buffer, it may not cycle Wolf reliably regardless. If it's a 14.5" with a carbine length gas system or a 16" with either length gas system, then I'd say that your tube/gas block is leaking too much gas. I've seen a few undersized gas tubes. It happens.

It's a franken upper I put together with colt 20 inch barrel chopped to 16.5 inch with barrel port opened up to .100
I put the origina GIl sight/gas block back on. The gas tube did not have any wiggle at all with that combination. Test fired a 20 round mag of Wolf Classic with it. All worked and even locked bolt back. I am happy with it now except I am stuck with useless tacticool gas block I paid $25.00 for. |

How is your new gas block secured? Does it move at all? Was it positioned properly?

No. It should not wiggle or leak gas.

I put a Vltor low pro gas block on my BCM middy and while the gas tube does not wiggle inside the gas block some "excess" gas does leak out a little bit right behind the gas block, on top of the barrel. I noticed this because my barrel is duracoated FDE and after I shoot about 30 rds noticable "black" carbon is shown on top of the barrel right behind the gas block. Big deal? No, never a problem in the 3,000 rounds at least put through it. If that helps you at all.
