Kingslayer and Liberator Update: Swampfox Optics

Swampfox Optics announces that our Kingslayer and Liberator dot sights are now available in either red or green circle dot reticles, in addition to the original 3 MOA red dot variants.

The Optics:
The Kingslayer is an RMR-footprint open reflex sight, a proven tough little optic that stands up great on reciprocating pistol slides. It’s also easy to put on rifles or shotguns as a lightweight dot sight with almost no weight penalty– we include a low profile 1913 Picatinny base in the box. 

The Liberator is a closed tube micro dot that comes with a low Picatinny mount and an absolute co-witness mount both included in the box. Liberator’s scope body is compatible with T1-style aftermarket mounts for shooters who prefer lower 1/3rd co-witness or quick detach setups. 

Both the Kingslayer and the Liberator feature push-button controls, battery replacement without re-zeroing, and motion sensing auto shut-off after 4 hours without movement. 

The Reticles:

Both sights are fine as simple 3 MOA red dots, but we wanted to step our game up. For the circle dot versions, the Liberator’s center dot shrinks down to 2 MOA while the Kingslayer’s center dot stays at 3 MOA, and both reticles feature a 65 MOA ring around them to grab the eye quickly and center it.

In testing, we found sight acquisition speed is boosted slightly with these reticles on long guns, but the biggest advantage of the circle dot comes in the Kingslayer pistol application, especially with new pistol dot shooters who haven’t perfected their presentation. If your alignment is off a little bit as you press out it’s easy to find a section of the 65 MOA ring and use that to start correcting your aim, instead of swirling your muzzle, looking through blank glass waiting for the dot to show up.

The Price:

We managed to keep our pricing the same as before, with an MSRP of just $219 for Kingslayer and $179 for Liberator. You can find them for less at places like Optics Planet and we like to throw sales during holidays too. (If you’ve made it this far, Labor Day is coming right up!) 

We’re damn proud of these optics, and all our products are covered by our 50,000 Round Guarantee. You can check out all the full specs and details at, and we’re pretty active on Facebook and the ‘Gram. Stand by for more new products coming from us soon. We’re working hard to make some bad ass optics that won’t break the bank.  –Swampfox Mike
