Wilson Combat Ar-15 Two-Stage Trigger 9Mm$195.95
Availability: In Stock
The Wilson Combat TRETUM2 Enhanced Trigger Unit is a precision two-stage AR trigger built for shooters who demand a crisp, predictable break without the fuss of adjustment screws. Drop in compatibility with standard USGI-spec AR-15 and AR-10 lower receivers means you get a genuine upgrade with no gunsmithing required. The TRETUM2 is machined from H13 steel and finished with DLC (Diamond-Like-Carbon) coating—a hard, corrosion-resistant surface that keeps the action running smooth even when your rifle is dirty and neglected.
Two-stage triggers reward precision shooters by separating take-up and release into distinct phases. The TRETUM2 delivers 4 to 4.5 pounds of pull weight and a positive reset that lets you keep rounds on target without breaking your grip. The DLC finish resists wear from hot powder gases and fouling, so your trigger will feel consistent year after year. This is the kind of upgrade that quietly transforms shooting from behind the bench or at distance, where trigger control separates good groups from great ones.
Wilson Combat engineered the TRETUM2 for standard GI-spec receivers and pinned trigger groups with .154" diameter pins. It's compatible with any USGI-pattern AR in 5.56, .308, or other calibers—but there are important exceptions. Certain early Colt commercial rifles, guns with proprietary pinned sear blocks, the Bushmaster ACR, and AR platforms with bolt carrier firing pin safeties require different solutions. Two-stage models are recommended for .22 LR conversions running high-velocity ammunition. The short, fast reset demands a firm grip and solid shooting position; bench and prone shooters should ensure they're holding tight enough to prevent unintended follow-up shots.
This is the no-nonsense choice for hunters, match shooters, and serious practitioners who want a better trigger without the debate.
| Brand | Wilson Combat |
| Model | TRETUM2 |
| Type | Two-Stage Trigger Unit |
| Trigger Pull Weight | 4 to 4.5 lbs |
| Material | H13 Steel |
| Finish | DLC (Diamond-Like-Carbon) |
| Installation | Drop-in, no adjustment screws |
| Compatibility | Standard USGI-spec AR-15/AR-10 lower receivers with .154" trigger pins |
The TRETUM2 fits any standard USGI-spec AR-15 or AR-10 lower receiver with .154" diameter trigger pins, regardless of caliber. This includes most modern commercial and mil-spec builds. It is not compatible with certain early Colt commercial rifles (1991–2009) with proprietary .169" pins, rifles with pinned-in sear blocks, the Bushmaster ACR, or any platform with a firing pin safety mechanism in the bolt carrier group. If you have questions about your specific rifle, verify your trigger pin diameter before ordering.
The TRETUM2 is a drop-in design with no adjustment screws. Installation requires only removal of your existing trigger group and insertion of the new unit into your lower receiver. No fitting, drilling, or gunsmithing is necessary for any standard USGI-spec lower.
The TRETUM2 two-stage model is compatible with .22 LR AR conversions and complete .22 LR caliber AR-pattern rifles, provided you use high or hyper-velocity ammunition for reliable function.
DLC (Diamond-Like-Carbon) is a hard, corrosion-resistant coating applied over chromium and tungsten underlayers. It protects the trigger mechanism from rust and fouling, reduces wear from hot powder gases, and helps your trigger maintain a smooth, consistent break even in dirty, neglected conditions over years of use.
