Shot my build last week and the ejection pattern showed I was short stroking. About 5:00. When I cleaned my rifle I noticed carbon build up around the gas tube roll pin. Is this a normal place for the gas to leak? If it is not normal, how do I fix it? Other than that the rifle ran great and I love the accuracy of the Nordic-Lilja barrel. 14 out of 15 shots, at 25m, went into 1 ragged hole, the 15th was a pulled flyer. I will post a pic later this weekend when I get it off the phone.

You need to explain your build and understand that jpeg is for a carbine shooting M-855/M-193. |

Yes i am talking about the jpeg. What are signs of a short stroke? I guess I don't know that it was truly short stroking. The rifle ran flawless with factory reloaded ammo. My build is on a Black Rain billet set with a DD BCG, Nordic-Lilja barrel, Larue low profile gas block, DD Lite rail, and an Ace Socom stock with a carbine buffer and spring.

Ejection pattern is not even remotely a good indicator of rifle function. Actual malfunctions ARE a good indicator of rifle function.

Cool. I guess I was just paranoid. No malfunctions in a little over 100 rounds.

Consistency is what we are all (mostly) looking for from our builds. Once you've been firing that rifle a while, you'll become accustomed
to how it operates (eject at 5:00) so when it changes, you'll know something is up or that you've changed something in the formula that affects the weapons operation. Nice barrel, what are the specs on it? |

As promised. 15 rounds at 25 m after sighting in irons and scope. Flyer was a pull on my part. Now I just need to stretch her legs, when I get a chance.
