Vang Comp Barrels

[The Sand Man]

I watched a few videos on youtube which mentioned barrels with constant constriction. They essentially eliminated the need for chokes by means of slowly narrowing from chamber to muzzle.

From what I've researched, they produce some very tight groups. Has anybody tried these or has any information about them?

The name Vang Comp was also dropped a few times in relation to this barrel design, if I'm not mistaken.

Cheers,

I wonder how the two designs would compare if you tried both out of the same gun with the same loads and same basic "choke", say both improved or modified. It makes sense to me that the "constant constriction" design might work a little better, as you're not cramming all the pellets together right at the end, but slowly pushing them together down the length.

It seems like the big drawback to this would be a lack of removable/replacable chokes... you'd need one barrel for slugs, one for grouse, one for skeet, etc. It probably wouldn't make a difference to those people currently running barrels with fixed chokes, but it might be a step back for anyone that uses removable choke tubes.

x2....isn't the whole idea behind chokes to have flexibility with one barrel....rather than needing 6-7 of them?

 

[The Sand Man]

From the perspective of putting this on a tactical gun, I don't think you're looking for extreme flexibility between slugs, sporting, and hunting.

Either way, for a tactical shotgun, you'd be able to shoot appropriate varieties of buckshot and slugs effectively, no?

I'm trying to learn as much as possible about all the varieties of shotguns and modifications before building my first defense shotgun. The Vang Comp system seems to produce some really impressive groups while maintaining much higher impact energy. The lack of sudden choke seems to really improve the performance.

True, if you plan on using certain loads, I'm sure you could come up with a happy medium in which both would shoot perfectly well... however, are you able to get these barrels in a "tactical" length? And secondly, you should consider your "lethal" range... if you're shooting intruders at distances greater than 40 feet, then perhaps you should reconsider your defense firearm, or your method of dealing with bad guys. This is just my own opinion, but I don't think the difference between a "standard" fixed or removable choke, and these "constant constriction" barrels, is going to be great enough at the distances you would see in a home defense situation. Mind you, I'm not well versed in choke patterns and effective distances and such, and I've never seen these constant constriction barrels, but I doubt you'd see that much improvement.

Still, it is your shotgun, and I know I do some things that people don't agree with, so I won't tell you it's a bad idea... I'll just suggest you consider your application before buying a barrel. Which reminds me: How much is a barrel? If the price is comparable, and you think it'll make a difference, then go for it.

I just emailed Hans Vang a few days ago to get info about his system but have yet to get a reply. He does have a Canadian dealer in Newmarket Ont but an email to them immediately bounced back.
I'd like to get more info about the possibility of his system on short barrel tactical shotguns.

Contact Casey at Tactical Ordnance www.tacord.com I'm sure he can answer all your questions.

I had my 590 barrel Vang Comped at TacOrd and it performed very well at the last EESA shotgun match.

Feel free to share some insight when you get the reply.

Awesome! Thanks a whole lot. I'll be sure to ask some questions about this "forcing cone elongation".

In regards to your mossberg, what do you think of it? How has it affected the groups with various shot sizes and slugs, what size are they before and after? Did you get the compensating ports drilled in as well? Do you find them particularly helpful? Also, what barrel length do you have?

I'm looking to build a really versatile shotgun, perfect for a camp gun, hiking in wilderness, and tactical applications. I think a Vang Comp system and some nice ghost ring sights could give me accurate slugs out to 100 yards, and buckshot to 40 yards.

Cheers,

Vang comp work is well worth the money if you plan to keep the gun, but it is an investment as the cost is not cheap.

My understanding is that the forcing cone is lengthened and most of the bore is backbored. The portion of the bore at the muzzle is left untouched, which results in some choke after the rest of the barrel is bored out.

Vang comp results are pretty impressive with bucks. However, I have no need for it personally since I have no plans of leaving my room in a HD situation. So anything over 5 yards is extraneous for myself. If you plan on doing some longer range shots with bucks, it's worth looking into.

I have the ports drilled on mine, its a 20" barrel, it reduces recoil a little bit, but it does make it alot louder. Shooting slugs with a Knoxx SpecOps stock and a Vang Comped barrel with the ports has less recoil than shooting target loads through a stock gun.

I don't own a Vang Comp barrel but I do have a 14" Cyl choke Remington barrel that this would be perfect for.

You haven't mentioned what barrel you'd have this performed on? I'd say that if it already has some choke (Imp, Mod) then leave it be, if not then go ahead.

YMMV but I've heard great things about Federals flight control wads giving really tight groups with buckshot. So much so that the Vang Comp mods weren't necessary, actually, lots of reports of this particular ammo not performing well in the Vang Comp barrels for whatever reason. At any rate, perhaps you should try some out in your shotgun and see how it performs before investing in the Vang Comp

Vang didn't invent this system. It's been around for many years and is more commonly called a "jug choke." Longer forcing cones, backbored barrel and a long taper to the barrel's orginal constriction at the muzzle will improve patterns in any gun.
