[ARCHIVED THREAD] - TRIARC Track 2.0 Accuracy (Page 2 of 2)

Quoted: @Molon Could you by chance do a velocity comparison between Triarc, noveske stainless steel, and say colt? This test would see how much difference if any in terms of velocity can be attributed to polygonal or single edge rifling versus normal button. I was actually thinking about doing something like that when the weather warms up. I prefer to do comparative chronographing inbetween 70-80 degrees F for apples to apples comparisons. Until then, the table below shows a velocity comparison between a 16" Colt with a 5.56 NATO chamber, a stainless steel 16" Noveske RECON with a Noveske Match Mod 0 chamber and a 16" Krieger with a match chamber.  .... |

Quoted: Any plans to evaluate a BRT barrel? https://www.ar15.com/forums/AR-15/BRT-Optimum-Accuracy-Evaluation/118-778084/ .... |

Quoted: What's the gas port diameter on the 14.5" barrel? If he doesn't know or doesn't get back, Triarc responded to me within hours when I asked about official gas port size of the 16". I was afraid yours might have been small or maybe they changed. They confirmed .070 to me. Their 12.5 is .078 per them as well. |
Here’s a quick demonstration showing how much even a barrel that isn’t considered a precision barrel can benefit from using handloads vs “mil spec” ammunition. The first 10-shot group pictured below was fired from my TRIARC Track 2.0 using my standard handload topped with Sierra 55 grain BlitzKings. The group has an extreme spread of 0.72” and a mean radius of 0.23”. After firing several seasoning rounds, I fired a 10-shot group of IMI M193. That group has an extreme spread of 2.44” and a mean radius of 0.86”.  ….. |

Quoted: FYI, My just purchased 16" Mid-length Track 2.0 has a .069 GP size. I don't have a .0695 pin gauge, But that is close enough for me. I'll be curious to see what you think about how gassy it is? Mine is gassier than I expected for the port size, with a YHM Turbo T2 on the end. |

Quoted: I'll be curious to see what you think about how gassy it is? Mine is gassier than I expected for the port size, with a YHM Turbo T2 on the end. Duly noted. I don't have a suppressor , but I can borrow one at the range. It may be a little bit before I get it assembled , so bear with me, please. |

About my same results with 193 Federal 55 gr |

I see Triarc now has a "SPR" profile for the 16" https://www.triarcsystems.com/product/16-track-2-0-spr-profile-barrel-5-56-copy/ |
