Iron Sights for Tactical Rails

[gparrish@premier.net]

I see some of you add a tactical rail system to your 870s. What are you using for iron sights?

I know LPA makes a rail version of their ghost ring rear sight product, and I assume any of the AR style BUIS would work, but I wondered how those would affect POI?

Thanks for your insights.

Hello,
I think standard AR-style back-up iron sights (BUIS) may shift POI higher due to the height of the sights over the barrel. You'd need to test and make adjustments. Moreover, sights mounted very far forward on the rail (like a red dot) can shift POI quite a bit lower
