hi guys,
yesterday i posted a question about how i thought my bcm bcg might not have it all totally together. after a lot of examination i found the problem of the tight fit and the bolt being really tough to move is because the gas rings are super tight... anyone know if its a good or thing? im sure if BCM does it its a hell of a good thing but im hoping one of you knows the science behind it and can put my mind at ease! (or even just tell me what it does lol) thats the one part of the bolt im not sure of the function thank you guys for all the help youve given me in all the threads i really cant thank you enough! |

Don't you already have a thread going on about this?
Yes, tight gas rings are a good thing as long as you're not seeing any malfunctions (I've never seen any from gas rings that are too tight). They act just like piston rings in a car's engine. They seal the gas inside the chamber where the bolt rides and help to ensure the gas stays put and does it's job of pushing the bolt carrier back thereby unlocking the bolt and cycling the gun. If they were loose enough, you'd start seeing cycling issues. Now stop worrying and go shoot the darn thing. |
