ET Arms

ET Arms is an American firearms manufacturer specializing in lightweight, affordable AR-15 platform rifles and components. The company originated in 2007 as PLUMCRAZY/E3 Arms, founded by Ed McInerney, focusing on producing completed lower receivers at accessible prices. In 2021, Tony DiChario acquired a 50% stake in E3 Arms, leading to the formation of ET Arms. By 2023, PLUMCRAZY transitioned to a dealer-direct model, offering complete rifles and accessories manufactured in the USA, all backed by a limited lifetime warranty. ET Arms is known for its innovative use of polymer and carbon fiber materials to reduce weight without compromising strength. Their flagship model, the Omega-15, features a 16" 1:8 twist barrel, a polymer carbon fiber-infused lower receiver, and a polymer upper receiver with metal inserts for added durability. The rifle includes a 15" M-LOK handguard, flip-up sights, and an ATI SR-1 Deluxe stock. It also incorporates a Nano Composite Saf-T-First trigger, allowing the firearm to be loaded with the safety engaged, enhancing user safety. Another notable offering is the PlumCrazy Gen 2 AR-15 pistol, designed for versatility in applications such as home defense and varmint hunting. This model features a 7.5" barrel with a 1:8 twist rate, a 7" M-LOK compatible handguard, and polymer receivers with metal overmold inserts, providing a durable yet lightweight platform. ET Arms' commitment to innovation and affordability makes them a competitive choice for shooters seeking reliable, lightweight AR-style firearms.
