Is this pin fit with ELF trigger ? Expert Answer

The KNS Precision AR-15/M16 Gen 2 MOD 2 Non-Rotate Trigger/Hammer Pins should work fine with that trigger.

Will these fit in a MAG tactical systems lower? I need extended trigger pins for a CMC drop in trigger.

Yeah mine has the reinforced areas and the trigger bars that came with the CMC trigger are too short to fit into my receiver so I’m looking for extended trigger bars. Anyone have any ideas where I can get extended bars to fit my receiver?

MUST HAVE ITEM by Robert Robinson, Verified Owner, July 14, 2020
If you've ever experienced trigger failure because of a retainer pin walking out on you, then you know this is a must have item. I had it happen only once and spent a lot with my local gunsmith to repair the damage which ultimately ended in selling t...

Great product! by RICH, January 24, 2020
I bought this for an AR 80% with anodizing of unknown quality. I don't want the holes to open up, so I installed the KNS pin set. It was easy to do, but I would watch the KNS video on youtube to get a better understanding of the process. You can i...
