Description
The LaRue LT270L is a direct-replacement mount that brings true quick-detach capability to your SureFire weapon light. It carries the same trusted design as the standard LT270 but adds LaRue's sliding locking sleeve, so you get a secure, repeatable lockup every time you snap the light back on. If you've ever wrestled with a factory thumbscrew that wouldn't stay put, this is the fix.
Installation is refreshingly simple. The LT270L takes the place of the existing SureFire M900, M951, and M961 mounts and swaps over in a matter of minutes with the included hardware. Once it's on your light, the LaRue speed lever clamps onto any MIL-STD 1913 Picatinny rail and the tension is infinitely adjustable, so you can dial in the exact fit for your specific rail without any slop or wobble.
Why the LT270L Wins Over the Factory Mount
Anyone who has run a Scout light knows the original mounting screw can loosen up under recoil and leave your light shifting around. The LaRue design solves that with a proper QD lever and a locking sleeve that holds zero. Users consistently report the wiggle disappears entirely after the swap, and pulling the light off for storage or transport becomes a one-second job instead of a screwdriver project.
Built the LaRue Way
LaRue has earned its reputation on precision-machined aluminum mounts that just plain work, and the LT270L is cut from the same cloth. It's a favorite among folks running lightweight, low-profile carbines who want their light exactly where they left it. Beyond SureFire lights, plenty of owners have adapted this mount to other gear thanks to its solid platform and adjustable clamp. It ships complete with everything you need to get it installed and running right out of the box.

Frequently Asked Questions
Which SureFire lights does the LT270L fit?
The LT270L is designed to replace the factory mounts on SureFire M900, M951, and M961 weapon lights, along with Scout light setups that use those mount styles. It swaps in place of the original mount in a few minutes. Once installed, it attaches your light to any MIL-STD 1913 Picatinny rail.
What makes the LT270L better than the stock SureFire mount?
The stock thumbscrew mount can loosen under recoil and let the light shift around. The LT270L adds LaRue's QD speed lever and sliding locking sleeve, which clamp down tight and hold position. Owners regularly find the wobble goes away completely after making the swap.
Is the LT270L quick-detach, and does it hold its position?
Yes, it uses LaRue's quick-detach speed lever so you can pull the light off and reattach it in seconds. The lever tension is infinitely adjustable, letting you fine-tune the clamp for your exact rail. That adjustability is what keeps it locked up solid with no play.
Do I need extra tools to install the LT270L?
Everything you need comes in the box, including the mounting hardware, a QD adjustment wrench, blue Loctite, and instructions. Installation is straightforward and typically takes only a few minutes. If you're removing a factory mount held with red thread locker, you may need to heat those screws to break them free first.
