I love this forend on my Mossberg 590 shockwave, not only looks amazing but it is more comfortable an sturdy than the original pump action. I feel I have more control of my shockwave. And the heat shield is amazing. Great quality and very easy to install, at least for me it was no more than 15 minutes.

Is it possible to attach a hand strap to the bottom of the forend? I’m slightly concerned about my hand slipping off the grip.

Do I need and extended forend nut??? I already have the forend nut that comes with the gun????? With Mossberg 500’s the forend tube is either 63/4 or 75/8 in length. Hence the need for a 1 inch extended forend nut. Or is the raptor kit compatible with both???

I just got (pending background check:)) the Mossberg 500 3-in-1 combo from sportsman’s (also sold at big 5) that has the pistol grip, reg stock, and 18.5/28 in barrels (hopefully that sounds familiar)…I’m pretty sure that I will need to get the action tube as you guys mention, but my question is: once I get that part from mossberg, will the forend AND heat shield fit???

Hi Alec,

You only need the slide action tube if you get one with a pinned forend. The firearm you are getting should work just fine as long as it is a 12g for the forend to fit.

I have a maverick 88 and noticed the remarks at the bottom. Do you sell part number 11603P? I looked on mossberg site and couldnt find it. Thank you

I have a Maverick 88 and say the bottom comment do you sell this part? Mossberg part number 11603P? If not where do I get it? I checked the mossberg site and they don’t have it on there

I’ve seen several videos that shows the inside of the pump needing to be carved out on aftermarket fore grips. Does this piece require any modifications in order to fit?

No modification required. Ours has an adapter so it fits both sizes of slide action tubes.
Team Shockwave

The adapter is for the longer 7 3/4 slide action tube that comes on a 500 and a standard 590. The 590 Shockwave has the 6 3/4 slide action tube and does not require the adapter. This kit comes with the adapter so it fits both.
