Hi all,
I’m going to be building a DMR/SPR/Reece Rifle from an m4 base.
I have a polarstar f2 engine to install in whatever body it is I buy,
what brand metal receivers often give the best alignment whilst still being good quality without skimping out.
has anyone put the f2 into a g&p vltor receiver, how would it fit, are they good quality etc (picture below)
thanks
adam
