Geissele Super 3-Gun S3G Trigger - AR-15 Single-Stage (05-152)
£279.00
Product Overview
The single-stage that made 3-Gun shooters switch — Geissele's S3G is speed engineered, not just lightened.
The Geissele Super 3-Gun (S3G, 05-152) is a hybrid single-stage competition trigger: a short, smooth rolling break with almost no perceptible take-up, paired with a reset so short and positive that fast pairs feel like one motion. Geissele designed it specifically for the demands of 3-Gun — wide-open hosing up close, precise singles at distance — and the pull handles both without changing character.
Because it is a Geissele, the speed comes from geometry and machining rather than weakened springs: ignition stays full-power reliable and the internals hold their feel across seasons of competition. A curved bow keeps the traditional feel for shooters who prefer it.
Why shooters choose the S3G
- Hybrid single-stage design — rolling break, minimal take-up
- Exceptionally short reset — pairs and strings blur together
- Full-power ignition — speed without light-strike gambles
- Competition-proven internals — consistent through high round counts
- Made in the USA

Product Questions
What does the S3G fit?
It is a drop-in unit for AR-15/M4 pattern lower receivers with mil-spec trigger pins. Check your pin diameter before ordering, since large-pin lowers require a different trigger. If you cannot tell, measure the pin holes or ask us with the receiver details.
What makes the S3G different from Geissele's two-stage triggers?
The S3G is a single-stage hybrid competition trigger, so there is no take-up stage to manage: the shot breaks in one motion. Its defining feature is a very short, fast reset, which is what competitors want when driving between targets. That same lack of take-up makes it less suited to a general-purpose or duty rifle.
How does it compare with the SD-3G?
Both are aimed at 3-gun, but the SD-3G brings the Super Dynamic flat bow to competition use, while the S3G is the single-stage hybrid with the very quick reset. If you prefer everything happening in one press, the S3G is the one; if you like a flat shoe and a hint of stage, look at the SD-3G.
Is there more than one version, and do I need extra parts?
It is supplied in a single configuration, so there is no shoe or finish choice, and it fits with your existing standard pins. Anti-walk pins are optional. You can compare it against the rest of our AR-15 triggers if you want to see the alternatives side by side.
What are the delivery and returns details?
Orders leave the United Kingdom with free tracked UK delivery, and tracking arrives by email when the parcel ships. If the trigger does not fit your lower, see our returns policy or contact us and we'll help sort it.
