THANK YOU!

An all-around excellent firearm.
I've put over 1k rounds through this in the past two months. It has held up flawlessly and I have not had one failure. It's extremely controllable, reliable, lightweight, and fun! The adjustable gas block works great as well. I wasn't expecting such a cool backpack to come with my purchase either. All around excellent firearm and purchase!
Thomas P. - Perun X16-105-Pistol
"...letting loose is where the Perun really shines. It's an amazingly soft shooter with very low felt recoil."
"The gun ran perfectly suppressed and unsuppressed on the same gas settings. In fact, we didn't experience any malfunctions or issues, even while purposely running completely dry."
Steven K. - Recoil Magazine
Being new to night vision I had questions, and AEA was able to work with me to get exactly what I was looking for. The customer service was great. Alex whom I spoke with several times was very helpful in questions for shipping. All around I feel this is a good trusting company to make these big purchases without any worry of getting the runaround.

PRE-ORDERS ARE OPEN
Expected to be ready Summer 2026

The Geissele Mid-Range Gas Gun (MRGG) was born from the Very Long-Range Semi-Automatic Sniper System (VSASS) program. Officially adopted and battle-proven by U.S. SOCOM as the Geissele MK1 MOD0 (MRGG-S), the Geissele MRGG MK1 brings this technology to the modern shooter, who demands uncompromising performance and precision.
Built from the ground up, the MRGG MK1 combines Geissele’s patented Phased Array® with Geissele Tri-Port™ Gas System, in-house Match Grade Cold Hammer-Forged Barrel technology, and fully ambidextrous controls to deliver a precision rifle greater than the sum of its parts. Engineered and hand-assembled by Geissele craftsmen for industry-leading accuracy, reliability, and a remarkably smooth shooting experience, it features a proprietary bolt group, and tuned buffer system to reduce felt recoil and enable faster follow-up shots. Whether in the field or on the competition line, the MRGG MK1 excels when every round matters.
The MRGG MK1 includes the attention to detail expected from world-class Geissele manufacturing.
For those who refuse to compromise, the MRGG MK1 sets the standard for flawless performance. Join the legacy of Geissele precision, reliability, and unmatched craftsmanship—and equip yourself with the rifle that defines excellence as the benchmark for success.
- Match Grade Cold Hammer-Forged Barrel – Flawlessly crafted in-house in North Wales, PA, delivering bolt-gun accuracy with gas-gun speed.
- Aluminum Billet Receiver Set – Steel-reinforced cam race and intuitive ambidextrous controls, including a dust-cover-actuated bolt catch and rearward release button for faster, instinctive reloads.
