Re: will this fit my mr1?
I'm not sure that would fit since it mentions 1/8" which eludes it has a 1/8" NPT thread. If the MR1 still has the old metric threaded stainless line, obviously the 1/8" NPT threaded gas through will not work. I think adding that rounded gas through would take away from the MR1's MilSim look anyway. Is that what you're trying to do?
