Bill Geissele’s wife’s company, ALG Defense, makes products for more of a mass-market than the very sweet, fairly simple, Geissele AR-15 triggers that live in more than a few SOF M4s and Mk. 11/12/18s, etc. (Indeed, sometimes the Geisele triggers are authorized MFP 11 or unit purchases, and sometimes they are installed on a catch-me-F-me basis by unit weapons men or armorers). Along with the triggers for full-on M4s and HK416s, Geissele makes improved triggers in both single-stage and two-stage variants for a wide range of semi ARs. They’re not cheap, they’re not always in stock, but they’re good.
ALG Defense makes simpler AR triggers — and now, an AK trigger, imaginatively coded AKT. In this video Bill explains the objectives this trigger meets and talks about some of the challenges involved in designing it.
The AK, Bill says, “has a ton of sear engagement.” That’s what you, the shooter, perceive as the very long and very smooth takeup of the typical AK trigger. (The SKS trigger has a similarly long, smooth engagement, suggesting that this may have been a standing Soviet / Russian design objective).
The result is an AK trigger that fits a variety of common receivers on domestic, imported, and kit-built AKs, and that reduces the trigger pull force and duration (including that all important very long sear dwell) significantly.
For example, Bill shows a graph of a stock AK trigger versus the ALG AKT; the stock trigger moves about 0.150″/4mm and takes about 4.5-5 lb. of pressure during that sear dwell period. The AKT takes up the slack more quickly and seems to come in about 0.065″ and just under 3.5 lb.
At about 8:30 he shows a 3D model (in Autodesk Inventor) of the trigger and walks through its function.
It fits some AKs with no fitting, but because of the wide variation in AK safeties, some AKs need a roll pin positioned so as to contact the safety. It’s explained in the video and in the AKT’s instructions.
