Reduced power spring for standard velocity ammo?
My M&P 15-22 shoots eley sport very well, but dosen't always run it perfectly. Is there a reduced power recoil spring that would let it function better with standard velocity ammo? The groups where noticably tighter at 50 yards than any of the other ammo I have tried. And I have about a case and a half of the stuff. Thanks for any info.
