Seems like it would do the trick - Phase 5 Weapon Systems Inc Sloped Quick Disconnect End Plate

I haven't fully installed this on my current build. I have however, test fit it to determine its ease of installation and aesthetics with my build. The FDE color is very similar to the other FDE products on my build - Magpul grip primarily. However, due to the shape of this end plate, not much surface area is left for the castle nut (~1/8") to properly torque down. I have recently purchased an armorer's wrench and magazine block with the intent of completing the install in the near future. The end plate seems to be well made and the part that protrudes into the lower receiver to assist with holding it in place is longer than a MIL-Spec end plate (which helps to keep it in place).
