Anyone use one of these? I'm looking to try something in 12.5 and see how much more velocity I get with 77g ammo.
The tabbed gas block seems like a simple but great idea. Would be shooting suppressed most of the time. |

My buddy has one on his sbr. It is very accurate. I don't have any idea on velocity though. It is a quality barrel.

I have the 12.5” CHF barrel. Haven’t done any formalized accuracy testing, but zeroing and velocity testing show it to be a MOA shooter with my 77gr TMK handloads (pre-developed moderate load, so not worked up for this specific gun/barrel).
Some velocity comparison for you: Magtech 5.56 77gr SMK (factory): 11.5” SR-15 @ 70* F ambient x5 shot avg: 2381fps 12.5” Centurion @ 85* F ambient x10 shot avg: 2516fps 77gr TMK HL (WG Brass, 23.2gr 8208XBR): 11.5” SR-15 @ 70* F ambient x5 shot avg: 2372fps 12.5 Centurion @ 85* F ambient x10 shot avg: 2466fps |

I have a build in progress using this barrel and the centurion pinned gas block. They are on sale now for $140, you should go for it.

That sale is why I'm leaning that way. I just removed the front sight base gas block on a 16" PSA upper I had lying around and put on an Expo Arms low pro gas block and UTG Pro Arwen M-lok rail. It shoots really well, and assembling to spec with a torque wrench wasn't difficult. I think it created a monster though. I finished up two lowers I had in the parts bin, and have a Geissele upper and charging handle coming today from the 4th of July sale. A blem rail already arrived, and a Geissele gas block is ordered so I can build a Blemula upper. There's two uppers left in my parts bin, so......  Attached File Attached File |

I’m a bit behind on my 12.5. I stocked up on some xm68gd ammo instead of buying parts. I did get a blem geisselle trigger for it during the last sale. I’m waiting for the centurion blem quad rails to be back in stock. |

I have no desire for a 10.3 but the price is tempting. Disregard my response you already found it while I was typing it out. |

I did order one. The smaller gas port size and sale price pushed me over the edge, as it will be used suppressed almost 100% of the time.
