Does this work with mounts that use a SureFire Scout Mount Footprint?
Affirmative. The Streamlight HL-X body mounts using the same scout-style footprint.
Can I use a SureFire pressure pad with this?
Not without an adapter. Arisaka makes one that we like.
What kind of batteries does this take?
The HL-X is technically a dual fuel light— it can run off of two CR123s or one 18650.
