Hi all,
I'm planning on building a 450 lower to match with this BCA upper:

What I'm struggling with is what buffer & spring combo to use with a rifle length A2 buffer tube. What would you guys recommend? Does anyone know if the standard assembly would be about right or if it would be optimized with a heavier buffer and/or spring? I have pretty limited build experience, so just looking for some pointers.
Thanks in advance!
Michael
