Overview
A 25mm red dot sight with the ACSS CQB reticle, BDC holdover dots to 600 yards for 5.56 and 7.62 NATO, and AutoLive motion-sensing power, backed by Primary Arms' transferable lifetime warranty.
The horseshoe-chevron reticle and auto-ranging marks are built for fast target acquisition as well as longer-range holdover. One reviewer flagged that the side-mounted adjustment knob can partially block a right-handed shooter's peripheral view in close-quarters use.
- ACSS CQB reticle with BDC holdovers to 600 yards
- Fully multi-coated 25mm lens, 1/2 MOA adjustments
- AutoLive shake-awake with 11 brightness settings
- 6.5 oz hardcoat anodized aluminum body
Who it's for
Shooters running carbines, shotguns or pistol-caliber platforms who want a durable holdover-capable red dot at a mid-range price. Right-handed shooters focused purely on max field of view in CQB should weigh the knob placement first.
Pros and cons
- Holds zero under sustained recoil
- Dot stays visible even with astigmatism per one reviewer
- Long battery life with shake-awake feature
- Transferable lifetime warranty
- Adjustment knob can block view for right-handed CQB use
- No QD mount included

Frequently asked questions
What reticle does the SLX MD-25 Gen II use?
It uses the ACSS CQB reticle, which combines a horseshoe-chevron for close range with BDC holdover dots calibrated to 600 yards for 5.56 and 7.62 NATO.
Does the MD-25 include a mount?
It doesn't ship with a QD mount according to buyer reports, so that's a separate purchase if you want quick-detach mounting.
