A ventilated (vent) rib is a flat plane that is raised above the barrel of a firearm — most commonly on shotguns.
What is purpose of vent rib on shotgun barrel?
Vent ribs are almost universal these days, and they are supposed to help dissipate heat and dampen mirage. In reality, a solid rib makes more sense for most field shooting, where we rarely shoot enough to heat our barrels.
What is a vented barrel?
Commonly found in extrusion, the vent ports are one or more openings located in the barrel that will allow for devolatization of the polymer as its being processed. They remove impurities in the form of volatiles that can have a negative impact on the process and product.
What does porting a shotgun barrel do?
This means that despite marketing hype, quality shotgun-barrel porting commonly reduces the shotgun’s recoil somewhere between 8 and 15 percent. In practical terms, the more powerful the load, the more effective barrel porting can be. So, if you shoot a light load, don’t expect to feel a huge difference with porting.
Is a ported barrel worth it?
Pros. Having the barrel ported has a wonderful application for those shooters seeking faster follow-up shots on target. The ports on the barrel are for reducing recoil by allowing the expanding gases to sort of thrust the end of the pistol downward. Great for competition shooters!.
Does porting a barrel reduce recoil?
A ported barrel doesn’t technically reduce recoil. Newton’s third law dictates that recoil’s full energy has to go somewhere. That said, it may reduce the amount of recoil a shooter perceives, making shooting more comfortable in the process.
What is a shotgun rib?
: a shotgun rib that is supported over the barrel by a series of fastenings to provide better cooling as well as a straight sighting plane.
Is it safe to look down the barrel of a gun?
There are a few instances when it’s acceptable to look down the barrel. If you are competent with the firearm you are handling, you have cleared the weapon, and it has not left your possession, then it is safe to look down the barrel.

The exception to this anatomy rule are people born with specific genetic anomalies. These can take the form of too many ribs (supernumerary ribs) or too few (agenesis of ribs).
Can you look down the barrel of a gun?
If the firearm in question is unloaded, it is unambiguously safe to look down the barrel of a firearm because the barrel is just an inert pipe. Looking down the barrel of an unloaded firearm is in fact the only way to conduct certain kinds of inspections.
Does a ported shotgun barrel reduce velocity?
Porting does decrease velocity, by up to 160 fps depending on barrel length. Porting does not reduce recoil. Porting can accelerate rust if not cared for properly.
How much does it cost to port a barrel?
Porting Services Price List Single barrel $99.50 Over/Under both barrels $167.50 Over/Under bottom barrel only $115.00 Side-by-side $135.00.
What is a ported barrel?
Porting involves precision-drilled holes also called ports in the barrel and/or slide on pistols, shotguns and revolvers. These ports reduce recoil by diverting the gases expelled before the departure of a projectile. The gases are directed out the top of the barrel which forces the barrel down.
Are rifled shotguns legal?
Under normal circumstances, any firearm with a rifled barrel over 12.7 millimeters (. 50 inches) is legally considered a destructive device in the United States. Now many manufacturers offer shotguns for sale with rifled barrels already installed.
Is a rifled shotgun barrel worth it?
A person would use a rifled barrel if they are looking at shooting longer distances. Here at the gun shop, we tell folks that if you’re planning on taking shots over 100 yards, then a rifled barrel is a good option to consider. Thus, it would be more accurate when your target is at a greater distance.
What is a magna ported barrel?
Mag-na-port offers a unique system of porting semi-automatics by using a trapezoidal port through the barrel and an oversized expansion vent through the slide to allow maximum dissipation without fouling. This process offers an alternative to shooters not wanting additonal weight or length from add on compensators.
What goes on the end of a gun barrel?
A muzzle brake or recoil compensator is a device connected to, or a feature integral to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise.
What does a compensated barrel do?
A Compensator is a device that’s usually attached at the end of a barrel. It’s objective is to take those gases and redirect them in a way that is advantageous to the shooter. Well if the gases are directed in such a matter, it will actually help the user shoot flatter.
What is a fluted rifle barrel?

What’s the difference between a muzzle brake and a compensator?
A compensator, much like a muzzle brake, is designed to reroute expelled gasses in order to achieve less recoil and muzzle movement. Whereas the brake tends to aid greatly in reduced recoil and only slightly in lessened muzzle movement; the compensator does the exact opposite.
What is the purpose of a high rib on a shotgun?
The raised-rib design allows the shooter to sustain a more comfortable head-up profile when shooting. And since the barrel is well below the rib, acquiring targets is easier and faster. A high rib is a magnet for briers, leaves, and tree branches, however, so this is not a gun that’s made for hunting.
What is a swamped rib?
Swamped Rib. Swamped Rib – A minimalist, smooth, concave, practically hidden, top rib on a side-by-side gun that connects the two barrels together, but provides no obvious extra aid to pointing—leaving the whole silhouette of the barrels themselves as the shooter’s frame of reference.
