    I replaced the aftermarket forearm on my A590 with the OEM Slide and nut from Mossberg

    Action Slide, 12 Gauge, 7 3/4


    Action Slide Nut, 12 Gauge, Blued, For 7 3/4" Slide Assembly

    so I could add an Insight Tech Forearm, Synthetic, 12 Gauge (Fits 7 3/4" Action Slide)

    Since taking everything down and spraying with Winchester Gun lube and patting the residue off the gun feels a lot tighter when I cycle it. It’s not stopping at some point, it doesn’t feel like it’s catching anywhere it’s just tighter than normal. I’m concerned before I put live ammo in there, does anyone have suggestions? Thanks!

    So the forend is just free floating?

    Can you look at the ejection port and tell if the bolt is sliding back and forth when you move the forend?

    Winchester gun lube does usually help reduce friction and make things slicker.
