Surefire Battery Door (Legacy Model) - LIMIT 1 PER MR.NEIN / MR.o7

Genuine Surefire Z-XBC (Legacy Model) for use with the MR.NEIN family of rail adapters.  These adapters may only be purchased with a MR.NEIN/MR.o7 purchase (Limit 1 per MR.NEIN/MR.o7 adapter purchased).  If you purchase one of these doors without the purchase of a MR.NEIN or MR.o7, your order will be refunded minus any payment processor fees that we incur.

These battery doors are a rip off and we would NOT recommend that you purchase one for use with MR.NEIN or MR.o7 unless you have exhausted all other options and simply don't want to go hunt one down.  If you would like to use a legacy style battery door with your adapter, we recommend trying an aftermarket legacy style battery door, or locating an OEM legacy style door second-hand.  Legacy style battery doors on X200's, X300's, and X400's are all compatible with the newer X300's that no longer include the legacy style doors.

NOTE:  In order to install a light as far rearward as possible (on MR.NEIN or MR.o7) with a "P" (Picatinny) rail key installed on a Surefire X300/X400 weapon light, you will need to punch out the silver pins on the side of this battery door.  Punching out these pins will allow you to remove the plastic block, which will allow you to mount the light as close to the trigger guard as possible, making the activation lever easier to reach.
