AR-15 / AR-10 / PCC – Drop-In Trigger – PDI BLK – 2 lb
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Hiperfire PDI BLK is a drop-in single-stage trigger built for AR-15, AR-10, and PCC setups that want a simple cassette-style install without giving up the harder hammer strike Hiperfire is known for. This model uses a curved trigger and H&M BLACKNITRIDE+ finish, with a 2 lb pull and design features meant to hold up under PCC blowback abuse.
This one is for the builder who wants drop-in convenience without the usual light-primer-strike baggage that gives some cassette triggers a bad reputation.
Fitment
- Fits AR-15, AR-10, and compatible PCC platforms
- Drop-in trigger kit for semi-auto setups
What it does
This trigger swaps the stock fire control group for a cassette-style drop-in unit with a light 2 lb pull, smooth feel, and strong hammer energy. It is built to simplify installation while still being tough enough for blowback PCC use.
Why it’s worth it
The value here is simple: easier install, light clean break, and a design meant to avoid the weak-primer-strike nonsense that makes some drop-ins frustrating. For AR and PCC builders who want a cassette trigger that still acts like it has a spine, this is a smart piece.

Tools needed
Basic AR trigger installation tools. Cassette triggers are simpler, but proper install and checks still matter.
Install notes
Confirm proper pin retention, safety function, reset, and reliable ignition after install. On PCC builds, verify the setup is compatible with the lower and that the bolt system is not creating weird geometry or timing problems.
Verify before you buy
Verify the platform is a compatible AR-15, AR-10, or PCC lower intended for this style of drop-in semi-auto trigger. If the build uses unusual internal dimensions or non-standard controls, confirm fit first.
