Are there such a thing?

Looking to see if there are any options to raise the hight of the front and rear sights on a Mini-14.

Thanks

There are none that I am aware of.  Your best bet is either a scope or red dot on the Ruger scallops for the Ruger rings or a rail in place of the front hand guard.  2 different companies make them.  The 2 are Utimak and the other is Omega.  The omega is the tallest one.  Many guys at perfectunion.com have gone with the Utimak and mount a red dot on the rail.  A few members have done the suppressor so someone has already done it.   here is a link:

Amega, not Omega.
