Gold & Silver Design Details

Extractor-Grip (specially for 410 conversions)

The Extractor-Grip is a patent-pending design feature on our Silver adapters that use .410 ammo. A pair of spherical cutouts allows the spent shell to be directly grasped for removal by the thumb and forefinger. This greatly eases the changing of shells. Other adapters on the market require you to have tiny fingers or use a stick to remove the spent shells. With the Extractor-Grip, you simply pull the spent shell out with ease.

The Slot

A patent-pending design feature on our 10-12,10-12XL, and 16-20 adapters. On adapters with a thin wall section, the material is not sufficiently thick to maintain its form. Our solution is simple, yet effective. A lengthwise slot allows the chamber to directly support the adapter during firing.

*Cases fired in split adapters will probably not be reloadable.

The Tapered End

Not all guns are equal. Some European designs have shorter chambers that require you to use hard-to-find 2-1/2” Ammo. The taper allows the adapter to reach past the forcing cone in these guns. All Gauge-Mate adapters (except 10-12XL) are designed to fire standard-length ammo from any break-action shotgun with all chamber sizes.

The Cutaway Rim

With GaugeMate-Gold, the cutawasy rim allows you to remove the spent shell without touching the adapter at all! The remaining rim portion aligns with the ejector/extractor so the adapter will move as it does. With the rim cut away, the end of the shell is presented for easy removal. Once the adapter is in place, subsequent reloading takes virtually the same time as using the normal ammo for the gun.

Friction Retention

To achieve proper operation in every model, there is a need to provide the necessary friction to retain the adapter in the gun, yet allow the ejector/extractor to present the shell for removal.
   Stvle A: 10-20.12-20.12-28. and 16-28
Three grooves of different depths may be used with standard or oversized o-rings to provide the correct amount of friction.
   Style B: 12-410.16-410.20-410, and 28-410
A single standard or oversized o-ring provide the right fit for the gun chamber.
   Style C: 10-12.10-12XL.12-16.20-28. and 16-20
Slotted feature provides the required friction in the chamber through spring tension.
