Trigger for the Labradar unit that will trigger off of recoil. Will work on anything from a 22LR to a suppressed system or with standard rifle and brake. Unit comes with adhesive velcro patches to attach to the rifle.
The trigger is very sensitive and some false readings may occur with hard bolt manipulation or dropping the BCG. Usually, these show as an error reading with no velocity recorded.
**Picatinny (£14) and magnetic (£17) mounts for the unit available separately.
