I’m planning a Fossberg 500 (space trench) build and saw under “thick receivers” there’s two options. 3 prong and 4 prong. Anyone know what the differences are? I’ve looked them over and can’t tell. TIA!

I totally thought the py2a 500 was just a reinforced version of the fossberg. Thank you for the information!
If anyone else sees this and has the same question, the “3 vs 4 prong” part is a threaded insert on the opposite side of the ejection port.
