| so i received my new Ranier arms barrel in today and i have a YHM low profile gas block sitting here. the barrel is exactly .750 but the gas block is .747 now my question is what should i do to get it on? do i sand down the barrel or should i sand the inside of the gas block. thank you. |

Brake cylinder hone
http://www.mcmaster.com/#cylinder-hones/=fkt9gt Don't touch the barrel. Rainier also makes a gas block that is specically designed for thier barrels. |

Quoted:
.003" isn't much. Can you try freezing the barrel and heating the gas block? It might be worth a shot before sanding, grinding or returning things. What does YHM say? They may have encountered this before and have an easy fix. +1 Freeze barrel over night. I would put it in a ziploc bag to prevent moisture. Or heat the gasblock in the oven for a bit. You shouldn't have to do both. Work fast and make sure it is lined up correctly the first time

I couldn't get my Troy gas block to fit so I used a medium butane torch and it went on with some force. Now it will come on and off easily when i loosen the set screws... Not sure what has changed haha...
Don't forget to put a light coat of oil on the barrel so you don't scratch it. It also helps to slide it on the seat. |

Heat it up. Had similar issue with a Larue lopro gas block on my GTS 6.8 barrel. heated it up with a torch while holding it with channel locks. Once good and heated, it slid right on and locked up tight. Make sure it's aligned correctly when you put it on because it will cool and clamp on quickly |
