I called Primary Arms to ask that same question. Since they made the ACSS reticle I thought it made the most sense to call them. They told me I needed to buy the strelok app and chronograph my specific gun/ammo to figure out what yardage to zero in-order for the ACSS to work properly. I wish they would publish the data for us so we don't have to buy a chronograph and ballistic calculators but it is what it is.

Does this use a T1 mount?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on May 31, 2022

The Holosun Paralow HS503G ACSS CQB Reticle Red Dot Sight uses the same footprint as the Aimpoint Micro T-1. So the Holosun Paralow HS503G ACSS CQB Reticle Red Dot Sight could use a T1 mount.

Q
Rick, member, from TX, United States, asked on May 07, 2022

What magnifier is recommended for using this and the low profile mount?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on May 20, 2022

I recommend using the Holosun HM3X 3x Red Dot Magnifier with the Holosun Paralow HS503G ACSS CQB Reticle Red Dot Sight. The Holosun HM3X 3x Red Dot Magnifier low mount allows for absolute co-witness height but also comes with a riser. It will work well with the Holosun Paralow HS503G ACSS CQB Reticle Red Dot Sight using the low mount. The magnifier can be found at the link below.

The Holosun Paralow HS503G ACSS CQB Reticle Red Dot Sight has the Shake Awake feature. So the optic shuts off during periods of motionlessness. The amount of time for it to shut off when not in use can be programmed.
