I think the purpose is to see more sky. A substantial part of the sky below the target is blocked by the barrels. If the target is going down or I have the gun pointed too high a raised rib gives me a better chance of hitting.

I have an old Model 21 someone set up for trap with 32" barrels and a Simmons ventilated rib. Like it fine.

I have seen the heat waves off of a hot barrel distort the site picture. Like looking through the bottom of a coke bottle.

Best,

Mike
