I ordered the Streamlight ProTac Rail Mount HL-X Long Gun Light and it’s says it’s 1.2”, will this work?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on May 26, 2022

The FAB Defense 1in Bayonette Lug Mount for Tactical Light/Laser will only accommodate lights and laser with a 1" tube. However, you could potentially still fit your light with the use of shims/washers on the retention bolt. But we cannot guarantee fitment.

If your bicycle horn has a 1" diameter tube/body, then yes. The FAB Defense 1in Bayonette Lug Mount would work.
