If I get my bolt ramped, will I finally be able to use my RRA NM trigger in it....I know it is a question of the hammer.......it has a notch, but not like a standard one.

Also...while I'm asking:

I'm not a Vulcan/Hesse man by any stretch of the imagination, but I purchased a Carbon Aramid upper and lower from them and want to build a light weight 9mm AR......will I destroy the lower in the hammer pin area? I hear they kinda take a beating.

Thanks

p.s.....just semi-auto
