Mount Height Options
The SPARC II can be mounted on a variety of platforms using various
combinations of the high mount, low mount and spacer.
Note: To ensure the attachment
screws do not loosen under use,
Vortex recommends using a thread
locker compound.
Mounting Tips
• When changing mounts, use the included wrench to loosen or
tighten the four screws attaching the mount to the SPARC II.
• When using the spacer, install this between mount and body of
SPARC II and use the longer attachment screws.
40 mm Extra-High Mount Height
Use the high mount and spacer to provide lower
1/3 co-witness on flat top AR-15 rifles.
37 mm High Mount Height
Use the high mount alone to provide absolute
co-witness on flat top AR-15 rifles.
18 mm Low Mount Height
Use the low mount alone for most applications
other than flat top AR-15 rifles.
21 mm Low-Plus Mount Height
Use the low mount with the spacer to add
additional height to the low mount if desired.
Multi-Height Mount System
