So who will be the first manufacturer to make a barrel extension for KSG ?
There are choke adapters out there already, so how hard would it be to make a barrel extension on a smooth bore.. ? I just think it would be a great idea, it would bring KSG to whole new level. I would imagine that 8" extension offered in different choke configurations would change things dramaticly.

Also another good thing to make would be some kind of magazine plugs, that limit the mag to allowed capacity for hunting.
 
I have never heard of an 8inch barrel extension

Thats interesting

Even more interesting is why a person would would want this in a KSG.

One of the big features is it being so short and compact.

Im really curious about this thread, and i hope others chime in.

Thanks

Why? To add versatility, KSG is the only SG I own, and I already know that it is well built, well balanced and accurate out to 75-100 yards with slugs.. But why not extend it's ability? IMO 18" shotgun is not that great for birds or skeet, but if there is an extension (6-8") choked at the end, it will result in slightly higher velocity and better shot pattern and will be more suitable for above mentioned activities..

Plus it would be quick to install, so you can only have it on when it's needed.

UTAS has been making it for a while:

Both of these statements are false. Length has negligible effect on velocity and pattern, unless the length is dramatically short. On a shotgun, barrel length only serves to enhance the swinging characteristics and increase the sight radius. However, as the KSG has a very rearward center of gravity and a fixed sight radius, even those effects will be negligible.

Agreed! Not to mention that the KSG has the absolute worst ergonomics possible for actual use on moving targets!

To the OP, you can contact Briley Chokes for a barrel extension. They will build you a 6" extension for $199.99USD.

Really, I thought the same physics aply to shot gun as to the rest .. Longer the projectile is in the barrel, more pressure builds up, more velocity... Are you saying 26" shotgun will have the same shot pattern as 18" one , at 15-25 yards ?? I don't think so..

Blastattack is correct! And as a guy that shoots an average of over 10000rds a year thru multiple shotguns...I can tell you the round to round velocity variance is greater than it is between an 18" and 26" tube with most factory shot loads. You will gain some velocity with slugs in a longer barrel but you can't take advantage of the fact due to the average rifled slug's inaccuracy beyond 125yards or so anyway. Chokes being equal, the shot patterns diameter will be the same regardless if you have a short or long barrel as well.
 
Very interesting. I'm not an expert on shotguns, so you must be right.. I learn something new every day !!

So then just adding choke adapter and chokes should do the trick, I guess.

You betcha! But if you want to get serious about wingshooting, then I recommend you save $20 a week till you have $400-600 and go buy an actual field gun. It'll be a whole lot less frustrating and rewarding for you, than it will be trying to modify your KSG into something it was never designed to do.

You are right, technically speaking. A longer barrel will increase velocity, but due to the incredibly fast powder that is used in a shotgun shell, the amount of change is minimal. Shotgun powders are completely burnt up in the first 2" of the barrel (some as fast as 3/4"), which means all your powder has burnt before the base of the wad exits the shell. You will see fairly large velocity changes from 3" (basically no barrel beyond chamber) to 6", and again from 6" to 12", but after 18", the velocity change is somewhere between 5fps and 10fps per inch added. The slow burning powders used in rifles can make each inch gain 50fps to 100fps.

+1 on that.

What this man said.
 
i saw a shotgun pistol at a gun show and it used the very idea that you have in mind were the barrel length went from 10 inches to twenty by the addition of a screw on smooth bore .i wonder how that would work on the ultra short shotguns . i think it is an idea worth pursuing .

It's not a new concept by any stretch of the imagination! Screw-in barrel extensions have been around for almost as long as screw-in chokes have been. Even the Italian companies that had external threaded choke designs had some choked extensions of up to 6" in length. They may not be common or well know but they do/did exist. Google "metrogun"...now that's a barrel extention for you! LOL! Also try "Browning Extended Swing chokes"...coke tube and barrel extension in one!

I don't see the point of making the KSG longer. I bought it because it is compact and holds lots of shells. I might consider the Remington choke adapter and some chokes but those are already available.

As for hunting I guess you are talking about bird hunting? I think a Remington or Mossberg would be better for that. I've been reading the Alberta regs and I can't find anything in there about capacity limits for a shotguns and big game. I want to take my KSG out and take a deer with it next fall. I am going to have to call the local conservation office before fall if I can't find a definitive answer by then.

in ontario we are limited to three rounds in our shotguns . it does not matter if it is waterfowl or deer . no limits for target shooting other than the limits on semi auto. i have never handled a ksg but i would imagine you could plug the magazine as you would any other tube fed shotgun ie. dowling .i see no logical reason that your gun would not be suitable for hunting deer as you said it is accurate with slugs and properly choked it would work for waterfowl. these bullpup configurations are a different kettle of fish and may require a whole new mindset to properly use than our traditional long barreled shotguns .i have to remind myself that even though it is a relatively short gun the barrel has over 18 inches of length .do not be discouraged by those that say it will not work as change is always resisted .have at it and see how it works .
