Julius's Review of Ergo Grip M-LOK Shockwave Mossberg 500/590 Tri Rails

Ordered this to replace the OEM forend on my Mossberg 590M. Note that item #4256 is the correct size for the 590M. Took about 10 minutes to install using the parts included and forend wrench (no need for any adapter nut). My 590M has a heatshield installed on the barrel and this forend does not interfere with it like other forends will, i.e. the Magpul M-lok forend.

The M-lok slots were to spec and I was able to install accessories easily. The provided rail covers were a plus as well.
Pros:
  • EASY INSTALL
  • Works with heatshield without modification
Cons:
  • None
Would Recommend: Yes
