Solid and ergonomic - FAB Defense M-LOK Compatible Handguard for Mossberg 500/590

Compared with my Magpul forearm, I much prefer the feel of this. It has great texturing, has M-lok slots to attach whatever your heart desires, fills the hand nicely, and fits tightly on the action slide. I would definitely buy this again. I think the only gripe I have was the lack of a wrench to help install and remove the retaining nut.
