how about building an AR15 from the ground up.. adding the "match" parts you want... it solves the well i like this but not this problem.
buy a stripped lower to start, and add parts from there like, triggers, stock, upper assembly.
doing this would probly end up being the second cheapest... overhaulingyour current would be the cheapest..
I have been a silent witness
to all of America's finest hours.
But my finest hour comes
when I am torn into strips and used as bandages
for my wounded comrades on the battlefield,
When I fly at half-mast to honor my soldiers,
Or when I lie in the trembling arms
of a grieving mother
at the graveside of her fallen son.
