Description
The Super APC is a joint effort between Geissele Automatics and B&T USA, and it brings genuine Geissele feel to a lineup that has always deserved a better trigger. If you have run a stock B&T fire control group, you know it does the job but leaves plenty of room for improvement. This one takes the crisp single-stage break and lightning reset of the well-loved Super 3-Gun and adapts it to the APC, SPC, and GHM family.
The pull comes in at roughly 2.75 or 4 pounds depending on which trigger spring you install, so you can dial in a lighter competition feel or a slightly heavier weight for duty and defensive use. It is a single-stage design with an M4 curved bow, which keeps finger placement natural and consistent from shot to shot. This is a non-adjustable unit with sear engagement set at the factory, so there is no fiddling required to get it running right.
What Sets the Super APC Apart From a Drop-In
B&T receivers are thicker than a standard AR lower and the hammer and sear pins sit a little differently, which is why generic mil-spec triggers can be a headache to fit. The Super APC solves that by using a different method of holding the hammer pin in place, and it ships with the correct receiver pins to make it work in your platform. Geissele recommends installation by a qualified gunsmith, mostly because the hammer spring tension takes a bit of finesse to seat cleanly.
Platforms the Super APC Fits
This trigger is built for the B&T APC9, APC45, and APC10, the APC223 and APC300 rifles, the SPC9, SPC45, and SPC10, and the GHM9 and GHM45. Whether you are chasing faster splits on a close-quarters course or you just want a cleaner break for precise work, it is a meaningful upgrade over the factory group. Maintenance is simple too, just an occasional drop of CLP or quality grease on the sear surfaces keeps things smooth.

Frequently Asked Questions
What guns does the Super APC trigger fit?
It is designed for the B&T semi-automatic family, including the APC9, APC45, and APC10, the APC223 and APC300 rifles, the SPC9, SPC45, and SPC10, and the GHM9 and GHM45. It uses the correct receiver pins to seat properly in B&T's thicker receiver. If you run one of these platforms, it is a direct fit upgrade.
How heavy is the pull on the Super APC?
The pull lands at approximately 2.75 pounds or 4 pounds depending on which trigger spring you install. The lighter setting suits competition and fast follow-up work, while the heavier setting is often preferred for duty or defensive use. It is a single-stage design, so you get one clean break rather than a two-stage takeup.
Can I install the Super APC trigger myself?
It is not a drop-in unit like a typical AR trigger, since B&T receivers hold the hammer pin differently and the trigger ships with its own receiver pins to handle that. Geissele recommends installation by a qualified gunsmith, largely because the hammer spring tension takes some finesse to seat cleanly. If you are comfortable working on fire control groups, it is manageable with the right punches and patience.
How does the Super APC compare to the factory B&T trigger?
It brings the crisp break and quick reset that the Geissele Super 3-Gun is famous for, which is a noticeable step up from the stock fire control group. You also get a lighter pull and the ability to tune the weight with the spring you choose. For anyone wanting more control and faster splits out of their B&T, it is a worthwhile improvement.
