## Questions & Answers

**Q: Is this ok to use on a springer**
A: I used it to mount a 30mm set of rings on a Springer with an 11mm dovetail holds quite strong I Have not had any issues with it :)

**Q: Will this fit bsa ultra**
A: Yes it would, how ever, BSA use a 13mm dovetail mount where this standard 9-11mm mount will not center over your barrel causing issues with zeroing, so for that reason I would not recommend it in this instance.

**Q: Will this fit a 12 ml dovetail**
A: Yes it fits perfectly

**Q: Will this adapter accept zeadio scope mount**
A: Provided your Zeadio is 20 mm picatinny then it should fit
