My M5e1 build

It's probably in here but using my phone it's cumbersome for this issue.

Dry fit the gas tube is short. What are the odds it will cycle? Both barrel and tube are supposed to be rifle length. Which is wrong? Gas port is .093, dwell is 6 15/16, 20" barrel.

You have an AR-15 rifle length gas tube not a AR308 rifle length das tube.

It might run it might not.

I guess stoner don't know the diff. Label shows both. Color me jaded to stoner.
