Frequently Asked Questions
Q: Will a heat shield fit my Mossberg 500 20” barrel?
A: Most heat shields are designed for 18.5” barrels, but some universal models may work with longer barrels. Check product specs for fitment range.
Q: Can I use a heat shield with ghost ring sights?
A: Yes, depending on your sight height and shield model. Some taller rear sights may interfere. Shields designed for bead sight setups are the most common.
Q: Is a heat shield just for looks?
A: No — while it enhances appearance, it also protects your hand from heat buildup during extended shooting sessions.
