About the Aimpoint Micro mounting standard
Aimpoint pioneered this mounting standard with the creation of their famous Micro red dot sight. Since then, the standard has established itself as the predominant choice for small tube sights – its popularity has prompted numerous other small tube sight manufacturers to copy it or introduce a modification of it. A wide variety of aftermarket mounts compatible with this standard are available. The standard features a longitudinal raised section running from the front to the back of the mounting surface, with a cut in the middle for a recoil stop. To ensure a secure fit, there are four screw holes located on the raised section, two at the front and two at the rear.

Modifications of the Aimpoint Micro mounting standard
GPO Spectra mounting standard
GPO Spectra’s mounting standard is almost identical to that of Aimpoint Micro, with one important difference: there’s a protruding part underneath the illumination knob. This means that, despite their similarities, adapters designed for Aimpoint Micro won’t fit the mounting standard of GPO Spectra, as this extra detail interferes with compatibility.

Hawke Endurance 1×25/1×30 mounting standard
The Hawke Endurance 1×25 and 1×30 models use a modified version of the Aimpoint Micro mounting standard, with a wider central raised section. This slight change means that adapters made for the Aimpoint Micro won’t fit these Hawke Endurance models.

Rudolph Optics 1×20 mounting standard
The mounting standard found on the Rudolph Optics 1×20 is similar to the popular Aimpoint Micro standard, yet it differs in one notable aspect: it lacks the recoil notch typically found in the middle of the lifted section. This absence makes it challenging to find a suitable aftermarket adapter, as adapter designed for the Aimpoint Micro standard come with a recoil stop. Apart from the missing recoil notch, the dimensions of the lifted section are practically the same.

The Vector Optics Maverick-IV 1×20 Mini mounting standard
The Vector Optics Maverick-IV 1×20 Mini uses a slightly altered version of the Aimpoint Micro mounting standard. The difference is in the spacing of the screw holes: it has an 8.8 mm distance between each pair of screws surrounding the recoil stop section, rather than the usual 10 mm. Because of this smaller spacing, adapters made for the standard Aimpoint Micro mounting won’t fit the Maverick-IV 1×20 Mini.

ADE Advanced Optics RD4-005 mounting standard
The ADE Advanced Optics RD4-005 adopts a slightly altered Aimpoint Micro mounting standard. The key change is a narrower recoil notch in the middle, designed to accommodate a Weaver rail recoil stop. As a result, the typical adapters for the Aimpoint Micro mounting standard do not fit this model. Additionally, the spacing between the screw holes at the front and the back is increased by 2 mm compared to the standard Aimpoint Micro mounting, adding another layer of incompatibility with the usual mounts.
