So I needed to get a extended/oversized bolt catch/release for the AR10 and since the options are fewer than that of the AR15 model, I purchased the Phase 5 BR V2 .308 and the made some mods to it to work for my application and the Norgon ambi mag release. I also nodded my ambi charge handle for greater ease of use. Check out the video for details.
