12 Gauge Perimeter Trip Alarm W/ .22Cal Adapter*

The FithOPS Perimeter Trip Alarm is made of 6061 Aluminum, this unit utilizes a spring loaded firing mechanism and a trip trigger. When the trigger is disturbed while loaded with a 12 gauge flash bang or .22 adapter, the unit will discharge. This device is compatible with 12 gauge power flash bangs, .22Cal CCI Power Loads, flares, and pepper gas depending on situation and requirement.

This new .22 adapter only works in our new, updated 2022 FithOps 12 gauge perimeter trip alarm, the one with 2 curved sides and 2 straight sides. It does not work in the older models (the square bodies). We apologize for this inconvenience.

.22 power loads are rim fires, that is why the hole on the top is not centered, it will not work if the fire pin hits directly on the power loads. This is not an error or machining issue. It is meant to be an offset center.

If removal of the spent powerload/ramset is difficult we recommend using pliers to pull it out the rest of the way.

Haven’t tried, seem solid, arrived quick

Mostly good

I ordered six. All of the pins had to be filed in order to slide out smoothly due to the sharp edge left behind from manufacturing. Also, with the .22 adapter installed, dry firing will result in striking the adapter face to the point of preventing new blanks from sliding in. This also had to be filed, but since dry firing wasn't advertised I won't mark down for that. Other than those, they're very well made devices.

I get more misfires with 22cal adapter than the regular primer or 12ga shell. I've maintained all of my trip alarms equally, the regular primer is more reliable.

We are sorry to hear that. What brand of 22 power load are you using? Thank you for reaching out.
