Hello all, I am using an Aero M5 lower and upper receiver along with extended M5 pivot pin to avoid the recess. What other brands work with the M5 lower? I am a KAC diva and would like to use their LPK and any other parts I can (minus pivot pin). But don't wanna drop the coin on any KAC stuff to...
I know all LPK are very hard to come by right now, whether 5.56 or .308.
But lets not focus on availability, lets focus on meeting my needs & then I'll search and destroy.
So what options are available in .308 LPK?
Is there a special manufacturer I should be looking for?
I remember reading...
