I have scraped all of the over-spray from inside of the chamber. This reduced the amount of drag bolt carrier would experience upon recoil. I have tried all of my magazines in other like guns. All of which work flawlessly. I have tried the lubricating the bolt with both dry and wet in regards to the amount of lube. I have tested firing a single round multiple times, all of which fail to send the bold all of the way back. This leaves me to assume that I have a gas tube that is not drilled to the proper diameter to allow the right amount of gas to fully recoil the bolt and chamber another round. What do you think?

greasypaws, runaway or reaper will probably answer your questions. I have shot the Wolf in my Glock without problems. But the Glock is more tolerant.

I think you are probably right as far as the gas tube. There is no reason the bolt wouldn't go all the way back, even if your buffer was way too heavy. There should be more than enough power to push it back. I had the same problem with my Bushmaster M4 for the first few mags, though. Every fifth to tenth round, the gun would fail to feed. It's gone through as shitload af ammo now with no problems, so I think it was a break-in period.

Dont quote me

On the R15 barrel does it say 5.56/.223 or just .223. Somebody had told me that they are chambered for .223. If this is the case make sure your ammo is marked .223 and not 5.56. easy way to figure this out is barel says:
5.56/.223=OK to use either .223 or 5.56 ammo
.223=.223 only

R15

I heard that the R15 is picky about ammo, therefore, I would try something other than wolf. shoot some good american brass cased ammo and see if it still has issues. If the wolf had lacquer cases, you may already have some build up on the inside of the rifle

I don't think the ammo

is the problem with this gun. Of course, it'd be easier if I could look at it, but it doesn't sound like a laquer issue. Laquer build up may cause a failure to chamber when the bolt comes forward, but it wouldn't be strong enough to cause failure of the bolt to retract all the way.

I've fired some Wolf

through my AR and had no problems with it.

It was my recoil spring. I had changed my stock to a collapsible six position type. The recoil spring is too rigid thus preventing successive chambering. Has anyone else run into this?
