Perfect for suppressor host March 19, 2026 Reviewer: MedicAl from WA, USA   Quality, craftsmanship and attention to detail on this piston upper. Create a perfect suppressor host with the adjustable gas block. Long stroke piston packs a little more of a punch than DI, but barely noticeable. It’s still very controllable, and a hoot to shoot. Pro tip: pair it with a proper PWS buffer and it shoots super soft. Was this review helpful to you?

Excellent upper December 7, 2024 Reviewer: E. Carroll from Willow, AK   Great upper! Excellent communication from seller. This is the second upper I have ordered from this seller. Shipping times took longer than expected. But, that is more to do with the postal system. Highly recommended. Was this review helpful to you?

Great upper, quick shipping August 19, 2022 Reviewer: Mike from Colorado Springs, CO   Order was shipped in no time, had time to take it out to the range last week. Shoots well - just playing around with buffers and springs for the time being. Sits very snug on an Aero lower. Was this review helpful to you?

Excellent Experience August 18, 2022 Reviewer: Scott Buchholtz from West Lake Hills, TX   My 300 Blackout purchase experience from Fortress could not have gone smoother. I received an email when it was in stock, and ordered it. Was off to the range a week later. Thank you Mike and the team at Fortress! Was this review helpful to you?
