I thought of that too. Only problem is the weird annoed barrels are almost always not going to be centerfeed. Maybe they can be machined to work? I have not got that far in my r&d. I was just going to thread the red smear one i have. Im going with an x valve on my red smear rt. The banjo bore in the rail is damaged and it leaks. I suppose i could sleeve the bore or bore it oversize and make a new banjo bolt to fit but i would rather drop the weight.Originally Posted by BigEvil
