There have been a couple people that monted the magnifier on the stripper clip rail, and an Eotech or Aimpoint on the EBR top rail, no DCSB required. It does take some small modification of the magnifier mount to make work though. Somebody will post pictures of the Aussie SAS guy with it, and Ironman will probably show his setup off too.

With a little skill shooting to 300 is no issue with an Eotech.
