I was perusing the the Hastings/Verney-Carron site when I happened across an interesting shotgun accessory, the Metro Barrel Extension (http://www.kebcollc.com/cart/store.php?crn=209&rn=596&action=show_detail). From what I understand, it's a choke tube extension that reduces recoil and noise; but, it's 32-inches long. If you add one of these, your gun may become a little front heavy. :eek:

Anyone have a guess where/when one of these would be an advantage?

Nope.

Slugs perform well out of a 22"-24" barrel and would likely lose considerable velocity in a barrel that long unless it was specifically loaded with a really hot powder charge.

Shot (buck, bird, steel) is pretty much the same story as above.

I see no benefit to such a creature... But that's just me.

The metro barrel is supposed to cut down on noise considerably, allowing you to shoot without disturbing the neighbors. But a 32" extension from a 26" to 30" barrel makes it a little hard to handle:eek:, probably why it never took off very well.

Advantage, just can't see one.

But I can see this in a CSI type show in a few months from now when the BG "assassin" needs to use a Silenced shotgun and the lead detective will say

"we need to check computer records for someone who bought a Metro Barrel Extension.........THAT's our KILLER". :D

I saw one of those demonstrated by Tom Knapp on a Benelli Super Nova a few years back.
It made the shotgun sound like a car door being slammed.

Got to shoot one that was attached to the barrel of a 391. Made the report low enough ear protection was not necessary - they are used to scare ducks and geese in city parks - but I bet you could use one goose shooting near houses to keep the noise down. It actually swung very nicely and everyone was able to crush 5-stand targets with it. I can get you that one, Zippy, for about $100 plus shipping if you want - fits Beretta Mobilchoke system

Marlin made factory pumps with a standard 40" MXR (Maximum Extended Range) barrel back in the 1970's and early 1980's. The original goose guns they made are legendary as well. I have a Stevens 940 36" Long Tom 12 ga. myself. All of these factory guns shot a better pattern with a standard full choke than anything we have today. There's no rocket science needed for not slamming your shot string together all at once. The longer, gentler chokes of the past definitely shot better. The turkey shoot guns used for money matches all wore barrels from 3-8 FEET in length, and included prop rods under the forend. One of our machinists at work made them as a side job. Of course today we do have Heavy Shot.

I believe it is a silencer under Califonria law.

Yep I think the only real purpose is to help silence the shotgun without using an actual silencer.

When does a ported extended choke tube become a silencer?

In California, here's the definition of a silencer:12500. The term "silencer" as used in this chapter means any device or attachment of any kind designed, used, or intended for use in silencing, diminishing, or muffling the report of a firearm. The term "silencer" also includes any combination of parts, designed or redesigned, and intended for use in assembling a silencer or fabricating a silencer and any part intended only for use in such assembly or fabrication.Since Verney-Carron site says, "The Metro Gun System was developed for shotgun shooting in areas or at times when noise was not a desirable effect." I suspect the CA DOJ would call it a silencer. Your state may differ, or have an exemption for one reason or another.

LP Brezney developed the Metro extension for urban goose control. Made for various shotguns by Hastings, I believe, and used with special subsonic ammo developed by Federal, it makes very little sound.

The extension screws in like a choke tube and is itself threaded for tubes matching the other end.

Out of production now.......

I've seem them marketed for crow hunting, acting as a silencer.

Crows are very smart, quickly learn what shots mean, so silencer keeps them from learning what the game is for a bit longer and allow the hunter to possibly take more birds from a set-up.

I saw him do that too.

It really helped reduce the noise, but it would also be very impractical.

Adding one of these on your shotgun barrel will let you poke the target out of the air if you miss it with your shells...

Dave - while these were marketed by Hastings, one must remember that Hastings didn't make anything, Verney-Carron did - seems they make barrels for many companies-both shotgun and rifle

True,1 oz, but with Hastings defunct I doubt we'll see many more offered for sale.

By anyone.....

Just use it as a club. Long barrels make it hard to "slice the pie" inside a dwelling...

I've got a Long Tom as well and love it for Turkey Shoots. A little 80w lube down the barrel prior to shooting at the event, LOOK OUT!:)

I have a new 32 inch Metro barrel extension sitting next to me - it was literally delivered 5 minutes ago via US Priority Mail. I purchased this from Kebco.com for $237 total ($225 + $12 s/h). This is a Verney-Carron, French made extension, the same as the original Hastings Metro Barrel Extension.

A 25 inch extension, the Raven, is also available from metrogun.com for $240 delivered, Remington threads only. Another 34 inch model, the Falcon, is available for the same price, and a 14 inch version is also on the way, for $210 - surprising results and compactness. All of the Metro extensions are American made by L.P. Brezny, the inventor and originator of the Metro Barrel Extensions.

Check the metrogun.com website for updates on thread/choke system availability - they're gearing up for just about everything. They have also mentioned design improvements for 2011. Not to mention that this company is owned and operated by the inventor of the whole metro barrel extension concept, L. P. Brezny.

The American-made, and discussion about design improvements make me wish that I had seen the metrogun.com website first. Oh, well, I just need to get out and go shooting.

Greetings SJSZR1 and welcome aboard.

I join 1-oz in thanking your for the links. If I may ask, for what application did you purchase your extension?
