Great option for builders and tinkering - Vortex Cantilever 30mm Ring for StrikeFire

I bought these after doing the math and realizing that I can mount my flip up sights underneath my optic by using these and changing out the nobs for QD levers. The absolute co witness did not disappoint, it works well with my front sight and LPVO when my magnification is set to 1x. The mounts hold firm and the quality is exactly what you would expect from Vortex.
