The RS20 delivers 1000 lumens with three output levels plus strobe, mounts in seconds with a quick-detach Picatinny mount, and runs on the CR123A batteries you can find at any gas station or sporting goods counter, or a single 18650 cell. Every RS20 includes a remote pressure switch, so you can run it from the tailcap or your handguard.
- 1000 lumens with High, Medium, Low, and Strobe modes
- Quick-detach Picatinny mount, no tools required
- Runs on 2x CR123A (included) or 1x 18650
- IPX8 waterproof
- Dual function tailcap switch plus included pressure switch
Three Levels for Real-World Use
Not every situation calls for full output. High gives you 1000 lumens for searching and identifying. Medium drops to 350 lumens for general use without washing yourself out on nearby walls. Low runs 150 lumens for close work and stretches runtime to 40 hours. Strobe is a click away when you need it.
Batteries You Can Find Anywhere
No charging, no cables, no waiting. The RS20 ships with two CR123A lithium batteries, which hold their charge for years in storage. That makes it a natural fit for a truck gun, a home defense rifle, or any setup that sits in the safe until the moment it matters. Already running 18650 cells? The RS20 takes one of those too.
On and Off in Seconds
The quick-detach Picatinny mount locks down tight and releases with a flip of the lever. Move the RS20 between rifles or pull it for cleaning without reaching for a tool.
Built for Bad Weather
The RS20 is rated IPX8 waterproof. Rain, snow, and wet brush won’t take it out of the fight.
Run It Your Way
The dual function tailcap switch gives you momentary and constant-on right at the back of the light. Prefer a support-hand setup? Mount the included remote pressure switch on your handguard.
RS20 or L3X?
Choose the RS20 if you want a simple, dependable light with multiple output levels, field-swappable batteries, and a Picatinny-equipped rifle.
Choose the L3X if you want maximum output (1250 lumens), USB-C rechargeability, native Picatinny and M-LOK® mounting with no adapters, and a lighter package. The L3X is our most advanced rifle light. Shop the L3X Series
