14" Vang Comp 870 barrel?
- Thread starter 308smk

I am the Canadian Distributor/Modification centre for Vang Comp Systems, however getting the 14" barrel is the problem.
There are only two makes of barrels for a Remington 870 that I will do and that is the Remington factory and the Dlask.
The only source for Remington factory 14" barrels is on the used market.
I have some Dlask 14" on order, however I have been told they could be quite some time.
If you can get a barrel, I would be happy to fo the VCS modifications for you.

Do you do all of the VCS mods?? I'm interested in the internal mods but not in the porting...

What makes the Dominion Arms barrels un-VANGable? Is it something technical (too thin?/specs?) or is it a personal preference/license/policy? I have a CanadaAmmo/Dominion Arms Grizzly (12-1/2") that I have been thinking of getting rifle sights/refinnish and a Vang-comp job.
I like that expression... "un-VANGable"
The Norinco and DA barrels are quite thin from what I have seen and are of unknown material. Part of the VCS mods is back boring which enlarges the bore diameter and of course that makes the barrel wall thickness even thinner. A very thin barrel of unknow material could have bad consequences.
As for 12.5" barrels, ports cannot be safely added on them as the ports would be too close to your off hand that is on the fore end. One might inadvertanly put his fingers over the ports and wind up with a very sore hand.

What choke are you guys running with your VCS barrels? Are they IC or Mod police barrels?
Do you see improvement in groupings will all ammo, or just buck? Are slugs more accurate post VCS?

I must confess, I have had my Casey 870 for over two years and have yet to shoot it...I wanted good kit but I am not a Shotgun guy.

Gentlemen:
If I may share some thoughts from my 870 whore days.............
MR canucklehead, the system is a little more complicated then simply thinking of it as a choke. Further while its not a new Idea (Trap shooters have been doing this for a very long time, and yes believe it or not I was and still am to a certain extent, a trap shooter) the application to shorter barreled for LE/military purposes is.
If memory serves, the process makes the lead (the area where the chamber meet bore dimension) a much more gentle slope, and then after that point, a very gentle and gradual tapper to the muzzle end. The effective choke of this system is actually modified, a constriction that would be very hard on 00 buck. However as the tappers are all very gradual, it make for very effective system with buck shot. (I have not tested slugs)
About the same time Sparrow commissioned his shotgun @ TacOrd, I was doing some extensive testing. Cassey was kind enough to lone me 2 identical 12 guage Remington 870 barrels, the only difference between the two was that one had the VangComp System, and one did not.
The details of my testing were as follow:
The gun:
For this test I used an old style Remington 870 wingmaster receiver in a CQB Mark 2 configuration (now of S&J Hardware fame) with Edin recoil buffer, none-folding sights, the above mentioned 18.5" barrels, and a 2 shot extension (looked very much like this:
Zero:
To level the playing field and negate any effects of barrel change to the sight plain. Each barrel was installed, and then a laser bore sighter was used to ensure point of aim at 15 yards, the mid point for our testing.
Targets:
An old style IPSC target (with head an torso) was centered and traced out on 2 foot wide by 4 foot long packing paper. An orange dot indicate what I considered high center of mass target point.
Distance:
For my purposes, I consider:
a. 25 yard the maximum effective distance for buck shot in most circumstances.
b. Anything less than 10 yards really does not reveal anything meaningful.
Ammunition:
As we can all a test 00 buckshot shells are expensive. To reduce the cost I use my own reloads. The load data was taken from the IMR shot shell loading reference table. The load consisted of a Winchester 209 Primer, AA red hull, 18 grains of 700x powder, under a WAA12R wad with 8 00 pellets of buckshot and 20 grains of buffer nested inside the wad. I personally reload each shell and can attest to the fact each shell was carefully loaded with the correct amount of pellets and projectiles in each shell.
Testing procedure:
Two of the above targets were set up for each distance and shot at separately. Stated another way there is one round per target, with 2 targets for each distance.
I tested the barrels with my not so prefect reloads at 10, 15, 20, & 25 yards respectively, however my testing with my reload can be best summed up in two pictures:
Normal barrel
VangComp Barrel
What we have here is typical of all distances, with a normal barrel you have an acceptable pattern that is pretty well on the edge of being effective with a pattern lacking center and density.
With the Vang Barrel, you have a extremely good, dense center of mas hit, with all pellets in the vital zone. To my thinking you could stretch this out even further, giving the lowly shotgun and even further effective range with 00 Buck shot.
It was my intent to do further testing with various factory loads and brands of ammo, however due to time constraints, that is where my testing ended.
The above are just my thoughts and I look forward to any comments you might have.
regards and all the best
