Hello guys, this is my first time building an AR, a decided I'd like to build my version of a mk12 or spr. I'd like this to be a high end build and I'm open to suggestions. I'd like to use as much carbon fiber as possible and make it as lite weight as I can. What started this was a hand guard I purchased thinking it was for an ar 10 , turned it it was for a 15. He handguard is a Christensen arms carbon fiber. I'd love to attach pics if someone can explain to me how.
