📖 New to HPA? This runs on external high pressure air — it needs a tank, a regulator and a line before it will fire a shot. Read our complete HPA guide before buying.
Three separate trigger adjustments, which is two more than most guns offer. Pre-travel, post-travel and actuation point all move independently on a CNC trigger riding a Delrin bearing. This one comes in Amethyst Purple.

On a binary setup the trigger is the gun. Two shots per cycle means every bit of slop happens twice, so the Article I runs a CNC speed trigger on a Delrin bearing — low friction, no grit, and it does not wear into a different trigger over a season.

What makes it unusual is the adjustment. Pre-travel sets how far it moves before anything happens, post-travel sets how far it keeps going afterwards, and the actuation point sets where in that stroke the shot breaks. Tune all three and you get a break you can repeat under pressure.

Behind it sits the standard Article I package — blacked-out INFERNO Gen 2 with Heretic Labs programming, 150mm inner barrel behind a carbon fibre outer, skeletonised billet receiver, 0.95kg and no stock, buffer tube or charging handle. Amethyst Purple is a finish Wolverine name as an option on the Article I.

Good to know

Heretic Labs sell the speed trigger as a separate part, so if you like it on this gun you can put the same one in an MTW. It is the same component.

Unstated by Wolverine: the bore, how long the gun is overall, the packing list, air consumption, and whether a battery comes with it.

Frequently asked questions

What is a Delrin bearing doing in a trigger? Delrin is self-lubricating, so the pivot stays smooth without grease and without picking up grit from the field.

Do I need tools to adjust it? The adjustments are on the trigger assembly itself. Set them once and they stay put.

Does the trigger affect the rate of fire? No, that is a board setting — 5 to 35 rounds a second. The trigger affects how quickly you can ask for them.

Is binary worth it on a short gun? That is largely the point of a short gun in speedsoft: get round the corner and put two out per pull.

Is Amethyst Purple the same spec as Midnight Black? Identical. Only the finish differs.

⚠ Always run a secondary regulator. Never put tank pressure straight into the engine. Set your output before you shoot, and chrono at the site every time.
