The new MaddMacs RMR Center Base 2.0 for the Ruger® MK Series pistols is a re-designed version of the original MaddMacs RMR Center Base with more features. First, the 2.0  has alignment pins machined into the base to accept all Trijicon® RMR Type 2 and SRO 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 RMR but has been shortened some in it's overall length and still undercut for the ejection port.  The T10 Torx screws used for mounting the base have been machined with a thinner head allowing the 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.
