John, buds description is very short but it says- FOSTECH FIGHTING HERCULES 556 7.5" ECHO-II. So this comes with the fostech echo ar 2 trigger. Hope this helps.

John, yes this model ending in A5 has the Eco AR II trigger. A4 would be the Echo Sport trigger and A1 would be the single stage trigger. >>> https://fostech.com/product/tech-15-7-5-hercules-5-56-pistol/ .....Have a great day!

Yes, a trigger AND a barrel are included with this pew pew.😎😁😂😆😂🍻
