Always wanted to try a Vltor MUR...just need to decide what stripped lower it would look best on. You have any pics Stick?
ADM. I like their implementation of the ambi bolt catch/release.
I have ALWAYS had good luck with Mega, and Noveske. I recently tried a set from SMOS, and was very pleased with them as well.
AXTS (Radian), Mega, San-Tan, CMT, SMOS, etc.
Man, there are A LOT of guys doing quality billet pieces. Hard to go wrong with the above, as well as the others that have been mentioned.....
