AEA Arms

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.

THE PERUN X17 - Built on the AR10/LR308 platform, the X17 combines the durability and versatility of the short-stroke piston system with the lower recoil and higher accuracy of the free-floated barrel in a well-tuned DI system. The finely machined 7075 top rail that slides with super tight tolerance on a 7075 core body and 6061 MLOK® handguard, creates a modular monolithic upper.
