Practical Note from neoPATRON
The PDI GS differs from the PDI BLK mainly through its straight bow and finish combination. The choice is therefore primarily about finger ergonomics and preferred configuration.
AlwaysSecond comment: I had been selling and using many triggers in AR-15. And do you know what I have realized? That these our toys need really good triggers, otherwise it sucks. You can save some bucks ... and then to be sad for years. And results will be (below) average and you will be wondering "Why the fuc...ing hell?" Then you will realize that it is enough to exchange the trigger and "who would have guessed", it works. I personally have my favourite in other trigger brand, but what concerns Hiperfire, those triggers are preffered all over the world, for various disciplines. Its qualities are proved also by the fact that they are being purchased from me, even by my biggest enemies. And why is that? Because todays trend is that "top-high-tech" overtuned triggers are no longer too much wanted and all want the reliable TOP. And there the Hiperfire has its place. They have abadonned the construction of old Mil-Spec triggers and therefore they have lost military tenders, but in civil sales they are the rulers. And that is why I can recommend them with no hesitation to all ARguys (although in my rifles is different trigger brand... which? You wanna know? ... I leave this on other times ...

Hiperfire USA – A Revolution in AR Platform Triggers. The trigger that changed the game through its unique “mechanical leverage.”
What makes Hiperfire different from its competitors – and why is it so sought-after?
It’s their obsession with technical innovation, precision engineering, and true functional design — not just another “polished mil-spec.”. Hiperfire builds its triggers differently, from the ground up. The Cam-Over Toggle Engine™ system delivers a light, crisp pull and clean break without sacrificing ignition reliability. Thanks to its unique leverage mechanism, it works on the principle of “the stronger the springs, the lighter the pull,” while maximizing hammer strike energy. A bold piece of engineering that goes against the old mil-spec trigger design of the 1970s — still used in AR-15s today not because it’s good, but because military specifications haven’t moved with the times.
Who are Hiperfire triggers made for?: For competitive shooters, professionals, and demanding civilian marksmen — all those who know how much a superior trigger really matters.
Why choose Hiperfire triggers:
- Absolute reliability – even in platforms where others may fail (like AR-9 blowback systems)
- Powerful hammer strike with comfortable pull – thanks to the negative leverage of the Cam-Over Toggle Engine
- Unique construction – fundamentally different from mil-spec triggers, offering far better control and feel
- Wide range of models – for AR-15, AR-10, AR-9 and more, in various technical configurations
- The choice of world champions – confirmed by top IPSC and other competitive shooters worldwide
- Made in the USA – unlike “marketing brands” mass-produced in China
