ALG Defense Act AR-15 Trigger Set ranked #114 of the 228 triggers builders added on GunPartPicker in September 2026. Builders have been adding it to their builds on GunPartPicker since February 2026. All time, it ranks #121 of the 503 triggers builders have added. Builds with this trigger are mostly chambered in 5.56 NATO (82%, then 6.5 Grendel 18%), split between carbine-length (43%) and mid-length (29%) gas systems, and nearly all AR-15.
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, but today 3 of the 8 retailers we track have it in stock. Prices barely moved in September 2026, holding around $72.94, so there haven't been real sales lately. Buying today, the lowest price is $82.95 at Primary Arms, above September's low of $72.94, so a better deal may come back.
