The Stag 15 Trinity Series is a partnership between Stag Arms and Trinity Force that offers a unique balance of durability and precision. The Trinity Series is built around a 16” 1/7 twist chrome-lined barrel and mil-spec chrome-lined M16 bolt carrier group.

The free-floating MX-15 M-LOK Rail from Trinity Force offers a lightweight profile that increases ergonomics and maximizes airflow while providing superior strength and durability. The rail provides ample amount of M-LOK attachment points and an uninterrupted picatinny rail along the top, which allows for room for sights, optics and accessories the shooter may require. The rifle is completed with a Trinity Force Cobra Stock, Trinity Force DI Slim Pistol Grip and Manganese Phosphate coated, chrome lined M16 bolt carrier group.

Every complete rifle from Stag Arms comes with a Transferable Lifetime Warranty, an Infinite Shot Barrel Guarantee, a magazine and a rifle case.
