Ray1970, I stand corrected, it is a 20 round PMAG. The carbine/mid/rifle length gas system is still a mystery to me so I appreciate your input about the 18" and mid length issue. Sounds like I might have to be a little more flexible for that.

cstone, I didn't want a 16" and thought that 20" would be to long for the boys so settled on the 18". That is the only reason and I'm flexible but hopeful. Jensen's is great but I just haven't decided on anything yet. I do want to get down to Bowers just from everyones comments on here about him being a great shop.

Thanks guys!
