The shockwave has a shorter barrel so that'd be a no. To dress up any plain barreled (without vent rib) Mossberg shotgun. Fits STANDARD 500 and 590 12 gauge models only. Comes with mounting instructions.

Hi Jose and welcome. Unfortunately, no due to the Shockwave's shorter barrel. You would need this modified Heat Shield : https://www.shotgunheatshield.com/mossberg-shockwave-heat-shield-590-shotgun-12-gauge-custom-rough-modified/ --------- Cheers, stay safe and enjoy!

Hi Jose, no sir, not compatible with 590 7-Shot models w/ +1 extension, 590 Shockwave, 590A1, 590M. I recommend the Black Aces Tactical Quad Rail Kit >>> https://blackacestactical.com/product/shockwave-rail-kit/ Stay safe & have a great day!
