The High Standard Model 10 shotgun is a gas-operated, semi-automatic, tubular magazine-fed bullpup shotgun. The design was developed in the late 1950s by Alferd Crouch, whose goal was to create the ultimate entry shotgun for SWAT units. There were two models: High Standard-10A and High Standard-10B.
The gun was never popular.
Design[edit | edit source]
The High Standard Model 10 is created by putting a normal semi-automatic shotgun with the stock removed into a polymer bullpup chassis.
The original design used a modified Remington semi-automatic shotgun. In 1965, Crouch sold his design to High Standard Manufacturing company, who used their Flite King model as the basis for the first model (Model 10A). It featured a rotatable shoulder stock, a built-in flashlight, and a carrying handle.
The 10B model was improved with a left-hand charging handle, a flip-up front sight, and a new flashlight/carrying handle mount. The flashlight is now removable.
The most common problem was failures to cycle correctly. The weapon was only to be used with magnum 12-gauge cartridges to guarantee function, but even these did not render 100% function. The trigger (as with most bullpup designs) was also less than desirable.
Additionally, it was unsuited to be fired by left-handed users, as the shells were very forcefully ejected to the right, which could potentially hit and injure the user. Usually, there will be a warning label on the right side of the weapon saying "CAUTION - DO NOT SHOOT FROM LEFT SHOULDER".
