ELF AR-9

Finding a trigger that works properly in an AR type pistol caliber carbine can be difficult. The bolt carrier in AR-9 type guns varies between manufactures. This causes compatibility issues with after market triggers. ELF Tactical thinks they have solved this problem, or at least improved the situation . . .

ELF Tactical told TTAG that they fitted their trigger into every available AR-style pistol caliber carbine platform — in both 9mm and .45 — and poured thousands of rounds through each firearm. Resulting in a very bold claim [via ELF Tactical’s website]:

The amazingly short take-up, glass-rod crisp break and next to zero over travel can be compared to the finest custom 1911 triggers.

Adjustability puts you in charge based on your current use. If you are looking for the finest adjustable trigger for your AR-9 / AR-45 platform, this is the trigger system for you.

Comparing an ELF-equipped PCC’s go-pedal to the finest custom 1911 triggers is a serious throw down. It’ll cost you $259 to find out the truth about ELF’s PCC trigger. Or patience; TTAG’s on the case.

  1. still waiting for that drop-in for the Sig MPX we were all promised with that trigger bar thingy. Geissele I’m looking at you. Someone please save me from the MPX’s god-awful gritty ass stock trigger.

    • This will work. That’s the purpose of the dual-sided disconnector thing. It’s designed to catch and slow the hammer so it doesn’t impact. Most pistol caliber carbines have the same issue of high bolt speed, and that’s one specific aspect of this design that they’ve worked around.

      • you are likely correct, but maybe how about saying on the website “hey this will work for MPX too” so paranoid folks like me dont shell out huge money not sure if it is going to work because manufacturer doesnt even reference the damn MPX (which is I have to think more prevalent than the MCX anyway). anyway, glad this will work thanks I learned more from you than from the manuf website which is NUTS.

    • I stopped waiting for them. Picked up a Hiperfire 24C Eclipse and haven’t looked back. Works and feels great.

      • I have a Hiperfire in my PCC. I get hammer follow with one BCG, but it works perfectly with another. I used to have an Elf trigger in there, but it had the same problem (also in my Sig MPX 9mm), so I moved it to a 300BLK AR-15.
        If Elf solved this problem, that’s a pretty impressive feat.

        • The redesign of the disconnector is supposed to do that. Catches the hammer and prevents it from impacting the disco. Like what the shelf thing at the rear of the factory MPX trigger does, but in a different way (catches and slows rather than provides an alternative impact surface).

  3. perhaps the best reason of all not to own a pistol caliber carbine in the first place:

    “im having a hard time with the trigger on this thing”

    pistol calibers are for pistols

    nobody in their right mind would put a 4 cylinder engine in a corvette

    same thing with the pcc

    • PCCs have been around almost as long as metallic cartridge pistols have. The appeal of having a long gun and a sidearm that take the same ammo was as obvious back in 1866 as it is today.

      The trigger issue discussed here is mostly related to using an AR-15 trigger designed for a delayed locking action 5.56 in a straight blowback action. PCCs aren’t wrong, but using components never intended for that use can be.

  4. Have been using a POF 3.5# trigger in my QC10 lower with Faxon gen 2 9mm BCG with Blitzkrieg hydraulic buffer very well, but the same setup in number 2 with an ALG double fires often. I’d try this if my POF wasn’t just about perfect for the $130 less.
