there is a odd thing about this firearm… took me a bit to remember this and then apply it…
right at the front where the rifle barrel joins the stock is VERY important for consistent accuracy!!!
when I went through boot camp we were issued m14’s… (up and on shoulders oh LORD LOL)
anyways when we went to the rifle range for quals… we were issued a different m14 and told…
do NOT disassemble it at anytime!!!
thought that was kinda odd but… orders ya know…
later when going to the armorers I noticed this odd shaped toll hanging on the wall…
looked like ti fit that part even had sorta a gut out for the gas piston and 2 clamp like parts…
ask about it and the armorer basically said that was none of my business… HMMMMM…
have looked all over online and such and have NEVER seen this tool!!!
BUT I did see a dis assemble re assemble guide and noticed something!!!
that piece which kinda looks like sheet metal that hook the barrel/receiver to the stock had a note…
24 lbs of pressure is required there…
ya need to apply a sorta downward bending action to that front piece…
then hook it up to the stock… so it mates up with NO play!!!
think you will find your M1A gets real accurate after doing that!!!
