I called TTI and was told they do not do just bolt work.They were the first people I called because I am currently using all there m2 parts and some of there AR-15 parts.I picked Hayes Customs do to a suggestion here and so far I am very happy with them. UPS lost my package and he contacted me asap them UPS found it and delivered it to him and he contacted me asap again and was very friendly the entire time.I also looked at his Facebook and the work he dose looks amazing i cant wait to get it back and run it in some matches.
