So got the new build out today. 12.5" with YHM Turbo K. It's over gassed. Shooting brass at 1:30-2. I was running a JP silent capture that was configured as an H2. This is my 1st build to be this over-gassed. I don't want to go to an adjustable gas block on this build. Do you think I can overcome that with an H3 and maybe a sprinco Red or Orange spring? is there any negative to trying to overcome that much as with weights and springs alone? |

Honestly, if that's the route that you decide to go I'd swap just the spring alone first and function test, adding the heavier buffer only if the spring doesn't correct it. Just to avoid tuning to the ragged edge of function or worse, short stroking. Easier to sort if issues arise. BRT EZ TUNE gas tube would be my preferred. |

yeah i will take a dedicated H2 as well and try various combos. I don't have an orange spring atm. Just have a red. As much as I'd like to go adjustable gas blocks/carriers/gas tubes, I'm trying not to introduce additional failure points or areas that aren't easily correctable if I needed to. |

Totally understand as far as anything adjustable. Check these out.....LINK Perfect solution to overgassed guns, IMO. No adjustments/ easy install. |

I have learned in other ventures that changing more than one thing at a time can often make things worse. Make a change and test, then make the other change and test, then both if necessary. |

So does it make sense to go with the suppressed carbine tube? Has anyone run the suppressed one without a suppressor? just curious if it runs. or does it make sense to go with the BRT EZTUNE Gas Tube - Preset - MIX CAR + 12" - 14" CAR? Their description says, "This is an application specific EZTUNE Gas Tube for Mixed Suppressed 11.5-12.5" barrels with CAR length gas system." @Tigwelder1971 |

I'd reach out to Clint (Clint Lupton is owner of BRT), great guy to deal with and will steer you straight. I've had mixed results tuning with buffers/springs, it's especially difficult "guesstimating" when the actual GP diameter is unknown, IMO. One statement that Clint has made stands out for me: "the amount of actual adjustment you can actually do to slow a gun down by adding heavy weights or springs is less than what a large gas port providing extra gas can do. " Accurate description. |

I had a overgassed 18 inch Daniel defense rifle length barrel with a gas block that I’d pinned so switching out to an adjustable gas block was not an option for me so I bought one of these adjustable gas tubes. Worked great I was able to dial it down,patterns at 3:20 and shoots as soft as a 22lr. https://defensereview.com/barnes-precision-machine-bpm-accu-set-adjustable-gas-system-for-competition-and-tactical-ar-15-carbines-range-video/ |
| I put a 9.3 oz rifle buffer in a 308 trying to slow it up. It did do that and ejects better but it does nothing for felt recoil. If anything it seems harder. Just a guess but restricting the gas may be a better option and take some of the pounding off the components. |

Quoted: BRT gas tube or change the barrel is the only options. Piling up more weight and harder springs is not a real fix. |

Good advice on BRT I invested in a pin gauge set along time ago- Example It’s easy to pull the handguard and loosen gas block to check gas port size Minimizes the guesswork |
| So got the gun together a few days ago. Fast shipping by Weapon Outfitters. Went to the range today. Started with a sprinco white spring and h1 buffer. Ejection patterns at 3pm. Feeding issues resolved. Decided to throw in an h2 buffer. Ejection changed to 4 o'clock. Felt even better on recoil. So very happy with this setup. The BRT suppressor gas tube worked great. |
