This service is for firearm orders only!
If you are ordering a firearm and would like us to install a KNS in the original bolt carrier, add this service and correct model of KNS for the firearm all on the same order. We will install the piston using the supplied KNS parts, and the original gas piston will be included in your shipment.
Our KNS piston listings can be found here:

| If you would prefer to have an aditional bolt carrier instead, we do have a bundle listing that includes a carrier body and KNS piston. https://armsofamerica.com/kns-piston-wbp-carrier-body-bundle/ *Note1: Sorry but at this time we DO NOT have spare bolt carrier bodies that will work with the 5.56 Beryl, but we do have the correct KNS pistons. **Note2: The 7.62 Beryl uses any 7.62 carrier that we have, but you will need to either remove/grind down the full auto shelf blocker pin that is in the rear trunnion, or file down the auto sear trip on a full auto carrier. |
