I just mounted an SWFA 3-15 on my SFAR and ran 15 rounds through it yesterday. Got about 3"++ groups at 100 yards. Not impressed. Some were handloaded 155 Amax over W748. However others were factory Federal Bonded Tactical 165grain. They shot over 3" also.
I noticed my brass was tore up. Double ejector plunger marks with brass flow on all factory rounds. Ejected hot and to the 5 oclock.
Not at all what I was hoping. Back to the drawing board.
