Does anyone know the history of vent ribs on side-by-sides?
I don't understand what role they're supposed to play or what advantage they're suppose to have.
Thanks

I like them on some SXS BUT some folks think that an XKE Jag is ugly They were proported to desperse heat waves Mike

Mike-
Thanks. I've heard that, but I wonder if it is true.
Is their height above the rib supposed to make you shoot higher? Is that an advantage?

They are supposed to dissipate heat of rapid firing better than plain barrels or solid ribs. Mostly, IMO, they are a fashion que.

Not only does a vented rib on a SXS not transmit barrel heat to the top surface of the rib thereby creating distorting heat waves but it also allows for a rib positioned higher at the breech end than at the muzzles (in order to have a more elevated POI) while eliminating the additional weight necessitated by a solid rib thick enough to replicate the same POI characteristics as the vented rib.

Having never seen a really low ventilated rib, I suspect that its addition is an attempt to wed the single sighting plane with the double barrel profile. To me, it doesn't make sense to try to achieve the sight picture of a single barrel gun with a side by side. The real advantage of a side by side is in estimation of elevation, as well of course as keeping ones' focus when swinging against a background of heavy brush. The advantage of the over under or single barrel is precision in the horizontal plane of the 90 degree crossing shot. Therefore the side by side really shines on live pigeon shoots or driven, incoming scottish grouse, or departing trap style angles, or rabbits against a brushy background, and other HUNTING presentations. The single barrel profile is winning the clay games, we might as well admit--even if it is a matter of contestant preference. Will an elevated vent rib change that and give the best of both worlds? Debatable, especially since it is hard to shoot and throw up at the same time...Steve

Who has a vent rib SXS besides me? Do you like the shotgun it is on? Do you shoot it well. I shoot mine quite well, BUT if you are LOOKING at the rib, you are NOT looking at the target Mike p.s. same with a swamped rib, matte rib, etc

Gentleman, It all relates to competitive shooting,pigeon, trap, skeet. Has to do with shooting enough shells in a small enough time to create heat waves that distort sight picture. That's all it's about. If you ever shot a round of trap doubles "100" targets when it is in the 90 degree range you know all about it. Bill

Given that the two barrels are on either side of the rib and within a fraction of an inch of it, I will go with the fashion statement explanation.

Any heat waves generated by a rib will be lost in those generated by the barrels. I have shot barrels on S x Ss mighty hot, but never missed a bird because of mirage. Biggest problem there is holding the hot barrels, and a vent rib ain't gonna help that none. SRH
May God bless America and those who defend her.
