The new MaddMacs RMR Dovetail Base 2.0 for the Ruger® MK Series pistols is a re-designed version of the original MaddMacs RMR DT Base with more features. First, the 2.0  has alignment pins machined into the base to accept the HolosSun 407C/507C red dots.  This will take all the guess work out aligning your red dot to the base and will help keep it secure.  As with original, the 2.0 is machined to perfectly fit flush with the HoloSun™ but has been shortened some in it's overall length and still undercut for the ejection port. Mount secures to your pistol in the rear sight dovetail and first scope base screw hole. The T10 Torx screws used for mounting the base have been machined with a thinner head allowing the 2.0 to be thinnest base on the market.  The new 2.0 mounts your red dot .0825" above the receiver!

• Made from 6061-T6 aluminum and DuraCoated in Black Oxide.
• Easy to install (instructions and hardware included)
• Will fit on all Ruger® MK Series pistols
