Heat Shield. Which one will Fit

[xk49]

I have the 870 tactical Magpul. I wanted to get the ATI Remington 870 Halo Heatshield, but is says it doesn't fit my model. Does anyone know of a heatshield that does fit this model?

Here's the one I want to get:

This listing doesn't say it won't fit my model, but other sites say it won't. What gives?

Never mind, I just went ahead and order the Mesa Tactical Saddle Mount with SureShell carrier. Thanks for all the advise.
