The '''DAO-12''' (Also known as '''Striker''', '''Protecta''' and '''Street Sweeper''') is a revolver [[12-gauge]] [[shotgun]] created for the purpose of riot control and combat.
The '''Armsel Striker''', also known as the '''Sentinel Arms Co Striker-12''', '''Protecta''', '''Protecta Bulldog''' and '''SWD Street Sweeper''' is a [[12-gauge]] [[shotgun]] with a [[Revolver|revolving cylinder]] that was designed for [[riot control]] and [[Combat shotgun|combat]].


==Creation==
==History==
The Armsel Striker was designed by Hilton R. Walker, a [[Zimbabwe|Zimbabwean]] (formerly [[Rhodesia|Rhodesian]]) citizen, in 1981. Walker subsequently emigrated to [[South Africa]], bringing with him the design for the Striker shotgun. His shotgun became a success and was exported to various parts of the world, despite some drawbacks. The rotary [[Cylinder (firearms)|cylinder]] was bulky, had a long reload time, and the basic [[Action (firearms)|action]] was not without certain flaws.<ref name="Wood2002"/>


Walker redesigned his weapon in 1989, removing the cylinder rotation mechanism, and adding an auto [[Ejector (firearms)|cartridge ejection]] system.

It was created in [[Rhodesia]] by [[Hilton Walker]] in the early 1980s. After Rhodesia fell, Walker moved to [[South Africa]], bringing with him the design for the Striker shotgun. His shotgun became a success, and found its way to all parts of the world. Even though it was successful, the shotgun still had its flaws. The rotary cylinder-type magazine was bulky, had a slow reload time, and the basic action was not without certain flaws.


A copy of the Striker was made by the US gunmaker [[Cobray]] and marketed as the SWD Street Sweeper from 1989 to 1993.<ref name="Walker2013"/>
Mr. Walker redesigned his weapon in the late 1980s, removing the cylinder rotation mechanism, and adding an auto cartridge ejection system. Mr. Walker's new shotgun was named the Protecta.

Using a rotating cylinder, the weapon's action is similar to a revolver's. Since the Striker uses a conventional [[Trigger (firearms)#Double-action|double action]] only [[Trigger (firearms)|trigger]] and a very large and heavy cylinder (compared to [[Handgun|handguns]]), Walker added a pre-wound [[Clockwork|clock-work]] spring to rotate the cylinder. This made loading slow, in exchange for a shorter and lighter trigger pull. The design was changed into having a cocking lever on the right side of the [[Barrel (firearm)|barrel]].<ref name="Wood2002">{{cite book|last=Wood|first=J B|title=The Gun Digest Book of Firearms Assembly/Disassembly Part V - Shotguns|url=https://books.google.com/books?id=Lo1IhoeGkTQC&pg=PA474|year=2002|publisher=Krause Publications|location=Iola, Wisconsin|isbn=978-0-87349-400-7|page=474}}</ref><ref name="Lee2011">{{cite book|last=Lee|first=Jerry|title=Standard Catalog of Rifles & Shotguns|url=https://books.google.com/books?id=QLlG3aX7enAC&pg=PT1403|year= 2011|publisher=Gun Digest Books|location=Iola, Wisconsin|isbn=978-1-4402-3014-1|page=1403}}</ref>
The reason one would favor the DAO-12 over an ordinary shotgun would mainly be because of the weapons magazine capacity and its capability of semi-auto firing. The weapon fires similar to a revolver, using a rotating magazine. Since the Striker used more or less conventional DAO trigger, and a very large and heavy cylinder (compared to handguns), the trigger pull for the conventional design could be flawed. Walker added a pre-wound clock-work spring to revolve the magazine. This proved to be a slow and ineffective way to load the weapon. Walker changed the design so that a front vertical grip is swung to the right and back to load a cartridge into place.


The first designs were criticized as having a slow and cumbersome firing process. The shells had to be individually loaded and then the cylinder's clockwork spring wound. Shells were ejected by an ejector rod along the right hand side of the barrel. The last version has the clockwork winding mechanism removed, the ejector rod replaced by an automatic ejection system, and a cocking lever in the rod's place that winds the cylinder automatically. The Striker has a twelve-round capacity and short overall length. Compact variants hold 7 rounds.<ref name="Wood2002"/><ref name="Lee2011"/><ref name="Firearms2000">{{cite book|author=United States.

The DAO-12 "Street Sweeper" shotgun has a modern tactical design, appearance, and color. It conjures connotations of military and paramilitary application in the minds of many gun control advocates unfamiliar with the use and operation of firearms. Accordingly, in the United States, this gun has often been politically labelled as an "assault weapon" unsuitable for non-governmental civilian possession. In reality, the DAO-12 functions mechanically in a way similar to any [[revolver]] or pump shotgun where one round is fired for each pull of the trigger. Unlike most real military guns with magazine interchangeability, the drum magazine does not detach from the gun and must be manually reloaded once expended.


==Availability in the United States==
The first designs were criticized as having a slow and cumbersome firing mechanism. The most advanced design has a pump-action style lever used to clear the chamber as other pump-action shotguns do. The DAO-12 is seen as somewhat unique for a shotgun because of its twelve round capacity and short overall length. The significant width of the drum magazine serves to limit its concealability however and, indirectly, its preference by criminals. The DAO-12's short length makes the gun favorable to some individuals as a home defense weapon for tight hallways and the close quarters of a small urban home. Its shot ammunition, as opposed to a solid bullet, also limits travel through walls and doorways, an important consideration for the urban dweller. The DAO-12 is difficult to (legally) procure in the United States of America as it has been labelled as a Class 2 [[destructive device]] under the [[National Firearms Act]] with "no sporting purpose" by the [[U.S. Justice Department]]'s [[Bureau of Alcohol, Tobacco, Firearms and Explosives]] (ATF) after considerable political pressure by the then Clinton Administration.
After a proposal by the [[Brady Campaign]] in 1993, Treasury Secretary [[Lloyd Bentsen]] declared the Striker and Street Sweeper [[destructive device]]s under the [[National Firearms Act]] the following year, their transfer and ownership becoming regulated by the [[Bureau of Alcohol, Tobacco, Firearms and Explosives]] (ATF).<ref name="Smith2007">{{cite book|last=Smith|first=Al|title=American Cultures: Readings in Social and Cultural History|url=https://books.google.com/books?id=fUjhpHSaVooC&pg=PA167|date=November 2007|publisher=Lulu Enterprises Incorporated|isbn=978-1-4357-0160-1|page=167}}</ref><ref>{{cite web | url=https://www.atf.gov/file/55426/download | title=ATF Rul. 94-2 | publisher=The Bureau of Alcohol, Tobacco and Firearms (ATF) | accessdate=6 May 2024}}</ref>

The Armsel Striker, also known as the Sentinel Arms Co Striker-12, Protecta, Protecta Bulldog and SWD Street Sweeper is a 12-gauge shotgun with a revolving cylinder that was designed for riot control and combat.

History

[edit]

The Armsel Striker was designed by Hilton R. Walker, a Zimbabwean (formerly Rhodesian) citizen, in 1981. Walker subsequently emigrated to South Africa, bringing with him the design for the Striker shotgun. His shotgun became a success and was exported to various parts of the world, despite some drawbacks. The rotary cylinder was bulky, had a long reload time, and the basic action was not without certain flaws.[2]

Walker redesigned his weapon in 1989, removing the cylinder rotation mechanism, and adding an auto cartridge ejection system. The new shotgun was named the Protecta.[3][4]

A copy of the Striker was made by the US gunmaker Cobray and marketed as the SWD Street Sweeper from 1989 to 1993.[5]

Design and features

[edit]

Using a rotating cylinder, the weapon's action is similar to a revolver's. Since the Striker uses a conventional double action only trigger and a very large and heavy cylinder (compared to handguns), Walker added a pre-wound clock-work spring to rotate the cylinder. This made loading slow, in exchange for a shorter and lighter trigger pull. The design was changed into having a cocking lever on the right side of the barrel.[2][6]

The first designs were criticized as having a slow and cumbersome firing process. The shells had to be individually loaded and then the cylinder's clockwork spring wound. Shells were ejected by an ejector rod along the right hand side of the barrel. The last version has the clockwork winding mechanism removed, the ejector rod replaced by an automatic ejection system, and a cocking lever in the rod's place that winds the cylinder automatically. The Striker has a twelve-round capacity and short overall length. Compact variants hold 7 rounds.[2][6][7]

Availability in the United States

[edit]

After a proposal by the Brady Campaign in 1993, Treasury Secretary Lloyd Bentsen declared the Striker and Street Sweeper destructive devices under the National Firearms Act the following year, their transfer and ownership becoming regulated by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).[8][9]

Variants

[edit]
  • Armsel Striker—Hilton Walker's first design.
  • Armsel Protecta—An improved version of the Armsel Striker. Readying the weapon for firing was simplified and the weapon's reliability was improved.[3]
  • Armsel Protecta Bulldog—An extremely shortened, stockless version of the Armsel Protecta. It is intended for building entry and vehicular duties.[3]
  • Sentinel Arms Striker-12—A fully licensed and improved copy of the Armsel Striker for the American market made by Sentinel Arms Co. It was available with an 18-inch barrel and a 7-inch stockless version.[5]
  • Cobray/SWD Street Sweeper—A lower-end clone of the Armsel Striker, having a limited parts commonality to the original weapons system.[5]
  • Cobray/SWD Ladies Home Companion/ LHC[10]—A reduced caliber version of the Streetsweeper. The trigger group is attached to a .410 bore or .45/70 Government cylinder and barrel.[11]
