Asked by:
Dane
- 11/30/2019
A:
We specifically designed this particular piston system to fit with the Aero Precision Enhanced handguards using our proprietary steel piston barrel nut. Since we didn't design this piston system to fit with other handguards we are unaware of any other handguards that are compatible.

Q:
Can you use a left or right sided upper side charger with the. 300 BO and more importantly to me the Grendel which I am doing ny best to save up to buy. Thank you -Hunter
Asked by:
Hunterdl
- 5/25/2019
A:
Our 300BLK you can't use a side charger because we have to build our 300BLK utilizing our proprietary upper receivers which use a rocker bushing in order for one to remove the piston system due to short gas length. To see this feature please click on link: https://youtu.be/fdvbPdPm-Xw The 6.5 Grendels can use side charging upper receivers, we will be adding more Grendel uppers to the product lineup over the next couple of weeks.

Q:
What makes this work as a non regulated system for both suppressed and unsuppressed, subsonic and super? Very apprehensive to spend this much on a system that I cannot find much information and reviews on.
Asked by:
Spike
- 4/17/2017
A:
All of our piston systems are designed specifically for each caliber, and then the regulators gas ports are specifically sized for the barrel and gas system length. We don't do any one sizes fits all because it is impossible for any one gas system to deliver the highest degree of performance that we demand of anything we build. What you see on our website is only a small part of what we do. We are primarily an R&D company that is 100% focus developing the most reliable and innovative firearms possible. It is not surprising that you are not finding a lot of information about us because we have devoted all of our resources to R&D and special projects developing next generation small arms. All of our retail sales are by word of mouth because we do not advertise. If you want to speak with me for a more detailed Q&A give me a call at 386.428.7960
