Leapers OP3 Micro SLS Features The Leapers Leapers OP3 Micro SLS Red Dot centers on a crisp 4.0 MOA dot reticle a size that balances precision with fast acquisition at typical defensive and range distances. The side-loading sensor design is the sight s signature feature allowing the battery to be accessed and replaced from the side rather than requiring the optic to be unmounted first. That design preserves the sight s zero across battery changes a real advantage for anyone who relies on the optic staying true from one range session to the next. The black finish keeps the sight visually unobtrusive on a slide or rail setup. Built compact and lightweight the OP3 Micro SLS is intended to ride low on a pistol slide or small rail section without interfering with the shooter s natural grip or sight picture. The housing is manufactured to withstand the recoil and handling that a defensive or range pistol sees on a regular basis. As a Leapers UTG product it carries the brand s reputation for delivering functional optics at an accessible price point. For shooters looking for a compact reliable red dot with an easy-access battery system the OP3 Micro SLS is a solid pick for sale at GrabAGun.
