These will be standard on our rifles and carbines, optional with our lowers.
The EPS is an evolutionary approach to ergonomics on simple pins, if your upper and lower receivers don't require a tool (a bullet is a tool) to break open, you might not really need them. The EPS is easier to push in and pull out, and more tolerant of mixed and mismatched uppers and lowers. While they may not be upgrades everyone needs, we deem they should be standard on every lower (and they will be on Battle Arms Dev. ARs).
They are the second last thing we had to complete for a Battle Arms LPK, the last thing is in development and will go to rapid prototype soon
