Hi all,
I been wanting to get a McGizmo L1 mule bezel build. Simply because of the two mode tailcap the L1 offers. However Don stopped making these. Here is a simple way to build one.

Any Aleph Mule bezel with single mode driver. Cell input optional. Mine is for a single cell and I run a 17670/16650. The size is identical to a stock L1 and I get the same UI as a McGizmo L1 Mule from back in the days.

So, if you have a Surefire L1 bored for a 17500 or an Extra LX2 body you can just purchase a readily available Aleph Mule and lego to your Surefire LX2 or bored L1.
