luispena, guest, from AZ, United States, asked on March 28, 2018

I have a 20 gauge adapter for my 12 gauge H&R break open single shot, will this item work out of my H&R 12 gauge weapon with a 20 gauge adapter?

Expert Answer
A
Answered by Ethan C., Gear Expert, from IL, United States, on June 05, 2018

Using adapters with adapters can be dangerous as there are too many factors that could lead to failure. We would strongly recommend instead going with the 12ga version of the adapter here: https://www.opticsplanet.com/chiappa-firearms-chiappa-x-caliber-12ga-357-38-gauge-adapter-insert.html and just swap adapters depending on what you want to shoot.
