Well not yet, but if a bunch of us E-mail ARMS
www.armsmounts.com/email.html & tell them that there is a healthy market for a spacer for use with the #19S ARMS mount & compact ACOGs', they just might make one!
I envision a sort of "reverse cantilever" spacer that will not only elevate the compact ACOG, but that will actually move it slightly rearward (and over a #40 BUIS) in order to compensate for the scope's short eye relief.
For many of us, full size ACOGs' are neither needed, nor desired. The compact scopes fill a real niche for carbines & rifles that are intended to be 300 meter max. weapons, yet finding a suitable mounting solution for flat top ARs' is next to impossible.
ARMS #19S directly on a receiver mounts the scope too low. #19S on a #38 rail is too high. Trijicon TA60 mount lacks throw levers & does not work well in conjunction with a BUIS. A spacer for the #19S is the best of all worlds!
C'mon guys... you know you want one!
Drop ARMS an E-mail & tell them to make it so!!!
