We have finally completed our B90/B92 to 1 x 18650 Battery Adapter.
Our battery adapters are compatible with both Protected and Non-Protected, Flat Top and Button Top 18650 Batteries.

There are 2 types: McClicky Switch Version and the Non-Switched Version.
The McClicky version works with Surefire 8x, 8NX, 8AX and L7.
The Non-Switched Version will work on all Surefire lights that use the B90 and B92 Batteries.
