Product Description

E2 is a unique process added to our chamber in the form of 4 channels that allow a small amount of gas to flow backwards and break the vapor seal on the spent case, pushing it into the extractor at the same time as the bolt begins extraction. This creates a push-pull extraction and nearly eliminates the chances of having a stuck case, while simultaneously prolonging the life of the extractor and spring by making its job easier and reducing wear and tear.

Patriot Ordnance Factory is offering a service to cut E2 channels into any barrel that is chambered in a SAAMI spec cartridge.  Please expect 2-3 weeks for this service to be completed.

All E2 orders require an RMA form to be filled out so we know whose barrel we have, and for what purpose.  Please click here for the RMA form.
