Dan T's Review of FAB Defense M-LOK Compatible Handguard for Mossberg 500/590

Buyer beware this forearm will not fit the Mossberg 590s shockwave without some additional modifications or an extended magazine cap! You will have to cut about two inches of the FAB forearm and shave down the grooves inside the forearm about an inch to get your Swivel nut on. It was truly a pain and didn’t come with any instructions. I ended up making the modified adjustments but in the process scratched my magazine tube and now I’m stuck with it. I don’t recommend this forearm for the shockwave unfortunately.
