I had looked into buying from either company,and although I havnt shot these companies product,I`ll have to give the hand to the
A10 or RBL simply because being a machinist myself and seeing pictures of said firms interiors,Galazan has the manpower and proper machines and its made in the United States of America.
You wanted a sporter,which means alot of rounds,then you need the support for it.Poli has like 3 guys,every part they make is a story unto itself including screws,metric sizes etc.
The only thing the Poli does have is that Euro flair,so
my suggestion is to drop the Poli and start looking at Merkels.
