So, I am building out my buddies AR-10 lower for him. He gave me everything he bought which included a LPK labeled .308.
While taking out all of the parts, and doing a quasi dri fit, i noticed the mag catch is too small (likely got switched with an ar-15 mag catch).
This got me thinking what other parts may be switched. He has a billeted lower where there are certain pins that would be very hard to extract, if they turn out to be the wrong size (bolt catch pin is one i immediatley noticed).
SO......does anyone know of a spec sheet that shows the differences between an .308 build kit and a 5.56 build kit? I want to make sure that I identify any other accidental AR-15 parts before i try and bury them into the lower without the ability to get them back out.
Appreciate the help!
