The basic design of the Model 10 shotgun was developed in the late 1950s by Alfred Crouch, a Santa Monica, California police sergeant.

Police, Tactial, Bullpup Shotgun Description: This is a nice example of the Collectable H.S.

Model 10B with the extended mag tube.

SIH to your FFl is 45.00 The High Standard Model 10 ( HS10 ) is a gas operated, semi-automatic shotgun that was manufactured by the High Standard Manufacturing Company of Hamden, CT.

It is easily recognized by its bullpup design, rotatable shoulder stock, and integrated flashlight.

Crouchs goal was to create the ultimate entry shotgun for SWAT and tactical units.

His original design used a modified Remington semi-automatic shotgun.

The Flite King was modified by replacing the stock, relocating the trigger assembly, and fitting a three-piece plastic shell around the receiver and first half of the barrel.

The rearward piece of the shell provided an attachment point for the rotatable shoulder stock.

Since the trigger assembly was moved forward to accommodate the bullpup design, a rod that connected the new and original trigger locations was used to allow minimal modifications to the original Flite King receiver.

Although the standard capacity of the Model 10 is 4 shells, there was a magazine tube extension available which would increase the capacity to 6 shells.

On the early model shotgun the 10A, the upper plastic section also housed the built-in flashlight and carrying handle.

The later model shotgun the 10B was improved with a left-hand charging handle, flip-up front sight, and utilized the new flashlight mountcarrying handle mounting block (which doubles as the carrying handle mount) as the rear sight.

The Kel-Lite branded flashlight can be removed, as it is attached to the aforementioned mounting block.

The concept of this shotgun was quite interesting to many police agencies who adopted the Model 10 in the late 1960s and early 1970s; however, most of the agencies found many shortcomings, and ultimately ceased using the Model 10.

However, even with the correct shells, the action would sometimes fail to cycle reliably.

Other problems that plagued the shotgun were the rough and unpredictable trigger feel, the strange rotatable shoulder stock, and the tendency of the recoil to cause the flashlights batteries to become damaged.

Another problem was that the Model 10 could only be fired from the right arm, as the gun ejected spent cartridges from the right side of the unit with a high force.

There is a warning on the right side of the shotgun reading CAUTION - DO NOT SHOOT FROM LEFT SHOULDER.
