PayPal only US lower 48 only No trades Up for sale is my ARES SR25 that I converted to the ECC configuration with a very nice Rare Arms rail and flash hider (both very hard to find and very nice). Inside the original gearbox has been completely replaced with a fully built Retro Arms gearbox. I will include the original gearbox that is fully complete with virtually no rounds through it. Gun shoots great. It cycles very fast with very heavy springs as well. The right side selector does not work with the retro arms shell unfortunately, I left it on to keep the look correct though.
