Gentlemen.
Bought a complete 308 upper with an si upper installed. Not a big fan of the lines honestly, but do to the lack of required kac wrench, im pretty much set with it.
I REALLY dont care for the lower. I have no need for grip grooves.
So,long story short, im hoping someone has experience pairing an si upper with another brand of lower.
Jd machine, a local outfit, looks to be the ticket, but they're by appointment only now.
Any help would be appreciated.
