If someone told you they hunt birds or ducks with a shotgun possessing a 48-inch barrel, you might start thinking of one of those old-fashioned punt guns from the days of commercial duck hunting. But that’s not what the Metro Gun is.
L.P. Brezny, a former police officer and gun writer, invented this 32-inch, screw-on barrel extension as an alternative to a shotgun suppressor such as the Salvo 12 for use in areas where nearby inhabitants could easily be disturbed by repeated 12-gauge shotgun blasts.
Many shooters have found the benefits of shooting a quieter gun in any number of situations, but getting the tax stamp required to own a suppressor isn’t the easiest thing in the world. Plus, the suppressor itself is an expensive piece of gear.
So how does the Metro Gun work? The extension screws right into existing choke threads. It’s ported along its entire 32-inch length, which allows gas to bleed off a little at a time before it smacks the air at the muzzle, making the resulting blast pretty quiet, at about 72 decibels, according to americanshootingjournal.com, comparable to closing a car door. It basically trades the baffles in a suppressor for length.
It also results in a good pattern, because the extension acts like a really long choke tube.
“Brezny routinely gets reports from Metro customers on how effective his barrel is for game. Ducks don’t fear after the first shot, and with no blast to drive them away, crows continue to come to the calling,” the story says.
That’s all well and good, but the thing is huge. Could it possibly be comfortable to shoot or use in the field?
From the story: “Would some consider the 32-inch Metro Gun a bit long and (unwieldy)? Probably, but Brezny insists that while shooting, the barrel ‘disappears behind the bead.’ Also, at only 1.1 pounds (the 25-inch Raven model weighs less), not much weight is added.”
The idea is worth some consideration, but could you see yourself packing this thing in a pack, screwing it onto your shotgun in the field and hunting with it? If you’re tasked with farm chores such as getting rid of some pesky crows near livestock or locals, it could be a useful specialty accessory. Current pricing is $257, plus $17 shipping with a required $100 down payment.
