Re: M1a trigger question
Have it tuned by one of the smiths listed here (take your pick, they're all good), shouldn't cost more than $75 to have done, then get it Melonited. I can PM you the info for the guy I go through... (his stuff goes to the same place SEI's goes to). He can put the SEI pins in it as well if you want, then just get a Tubb CS hammer and op rod spring and you'll be set.
