I finally ended up with an M1A and about 8 hours later the order for a Troy MCS chassis was made. After the fact I looked at what is needed for install and it appears to be a pain in the ....well you get the idea. Anyone have a recommendation on a gunsmith that has experience with M1A's? I may just end up hitting "buy" on my cart at Midway with castlenut pliers and a gas block tool but thought I would try this first. Thank you all in advance for your help.
