Do I have to remove the delta ring to replace the dust cover? My project rifle is almost done and I'd like a different dust cover but not bad enough to remove the delta ring.

Thanks

If you mean the handguards, then i dont think so?

Actually, I think you do! I havent owned an AR with a delta ring in a million years, I gotta check reference manual....

Yeah, looks to me like you do. You need to be able to slide the DR assembly foward to release the port door rod.
