Bob's Review of Ergo Grip Mossberg 500/590 M-LOK Rail Forends

First for people like me who were wondering what Mossberg shotguns this product fits. This is for Mossberg pump shotguns that have the 7 and 3/4 inches action tube. I installed it on a Mossberg 500.

The product came in really dirty and dusty for some reason, but nothing that couldnt be wiped off clean.

Installation was easy provided you have the tool to remove the castle nut in the action tube. The product does not come with one so make sure you have a way to remove that castle nut.

My small nitpick is that the forend is not high enough to cover the gap between the barrel and the magazine tube. The pictures are at angles that dont show this gap. It's also not high enough to cover where the 2 action arms meet the action tube. These are small aesthetic nitpicks.

Overall i like it. It makes my shotgun look more aggressive. It allows me to attach M-Lok accessories without having to modify my heatshield unlike the Magpul forend alternative which is bulkier.
Pros:
  • M-lok
  • Lightweight & compact
Cons:
  • not tall enough to cover the 2 action arms attachment point
Best Used for:
  • M-Lok Accessories
Would Recommend: Yes
