The Wolverine Heretic Labs Article I HPA MTW M4 Airsoft Rifle in the sexy purple color sets a new standard in airsoft engineering. Manufactured by Wolverine Airsoft, this high-performance HPA airsoft rifle combines the leading edge of current technology and user-friendly design to help it stand at the top of the yardstick of choice for both competitive players and serious enthusiasts.

All at a minimal weight of 952.54 grams, or 2.1 lbs—a lightweight rifle to be responsive and nimble in the field. The 150mm inner barrel included with the airsoft rifle is made with just the right diameter for the best in accuracy, so you can have your shot where you want it every single time. The result is a rifle that can easily accept aftermarket upgrades thanks to the universal VSR-compatible style hop-up packing and barrel, along with an AEG-cut barrel and hop-up.

The real internal appeal of the Article I is within the Gen2 Inferno HPA Engine that allows for a very wide range of FPS, between 295 and 420. Input pressure is adjustable within 60-140 psi, allowing a great range that the player himself can set on the rifle. The integrated fire modes of the rifle are just great, with settings for Semi, programmable Burst, and Full-Auto along with a safety mode. The rate of fire is adjustable from 5 to 35 rounds a second, allowing completely customizable shooting experiences.

The 14mm CCW thread direction is the same as any other Wolverine Heretic Labs Article I HPA MTW M4 Airsoft Rifle, and the rifle is also compatible with other accessories and suppressors. It uses a 7.4v 250-500 mAh battery with a JST plug that conveniently fits inside the pistol grip. (Battery is sold separately). Adjustable hop-up. Done right. This airsoft rifle screams high-end performance and quality for the serious airsoft player. The magazine, exclusive patch, and manual make it pop as soon as you open the box. This isn't an airsoft gun; it's a statement of high-end performance and quality.

This comes with a federally mandated blaze orange tip.
