I’ve personally seen 8 comp triggers go down in the last 2ish years. 5 were AT-X’s, one was an AX retrofitted with a comp trigger, one was an AT retrofitted with a comp trigger, one was an AXSR, which from the way it adjusts and from what I can see on the outside is a slightly larger comp trigger.
All were failures due to dust/dirt, all were in factory, un-fucked-with configuration when they died, round counts between 100-1000, so not exactly old either.
They all presented themselves with the same symptom(s) of the sear not presenting itself high enough to catch the firing pin & getting stuck in the “fired” position, or having a dead trigger on a cocked bolt.
I haven’t had trouble with the “comp-ish” trigger in my AXSR, and I’m not going to say that those failures are the rule instead of the exception, but the failure rate of AI/XTSP comp triggers is incredibly high compared to anything else I’ve seen on the market, 700 pattern or otherwise.
The same trend has been apparent in the XTSP 700 pattern triggers, so it’s not exactly a surprise this is happening.
