Great Fit on Mossburg 590 by Jay, Verified Owner, June 14, 2024
Great fit to replace OG forend. The low profile was perfect for the heatshield. I didn't have to crimp it to be compatible. Would purchase again if needed and would recommend many times over if you have a heatshield.

Perfect low profile Mlok handguard for Mossberg 500 by Jason Helper, Verified Owner, August 2, 2023
Fits nice and fit, and low profile like the OEM corncob,, but much much better. Has Mlok on both sides and underneath. What’s the biggest plus is, you can still run your HeatShield. I believe it might be the perfect forearm for the 500/590.
