Q
mitch, member, from NC, United States, asked on January 27, 2020

Does it come with a AR mount or taller mount for AR platform?

Manufacturer Answer
A
Answered by Primary Arms Optics, Manufacturer from TX, United States, on September 10, 2020

Greetings and thank you for your interest in Primary Arms. The SLx 25mm red dot includes the low base, a standard riser, and two different height spacers, as well as appropriate mounting hardware. With just the low base, a central height of 0.96” can be achieved. Add the standard riser for 1.41”. With the riser and thin spacer, your central height will be 1.54”. Using the thick spacer will place the optic at 1.64” height.

bob, member, from AR, United States, asked on January 15, 2023

why does the red dot on my SLx 25 look like a splattered star

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on May 04, 2023

This can be a result of multiple factors including the brightness being too high, reflection from the glass, astigmatism and more. Email us at Techsales@opticsplanet.com for further information/assistance.
