VictOptics SRD 1x18x20 VOD Reflex Sight (RDSL34)

The VictOptics SRD 1x18x20 is a compact enclosed-emitter reflex sight designed for shooters wanting the durability of modern duty-style optics without the premium price tag. Built around the increasingly popular ACRO-style footprint, the SRD offers a rugged, low-profile solution for rifles, airguns, airsoft platforms and compatible optic-ready pistols.
 
Unlike open reflex sights that expose the emitter to dirt, rain and debris, the enclosed design helps protect the electronics while maintaining a clear sight picture in adverse conditions.
 
4 MOA Dot for Speed and Precision
The SRD uses a 4 MOA dot, striking a practical balance between rapid target acquisition and accurate shot placement. Large enough to pick up quickly during fast shooting, yet small enough to avoid covering excessive amounts of the target at longer distances, the 4 MOA dot is one of the most versatile dot sizes available.
 
Whether mounted on a PCP air rifle, tactical rimfire or airsoft platform, the reticle remains quick and intuitive to use.
 
Enclosed Emitter Design
One of the biggest advantages of the SRD is its enclosed emitter construction. Unlike traditional open reflex sights, the LED emitter is protected within the optic housing, reducing the likelihood of dirt, moisture or debris interfering with operation.
 
For shooters using their equipment outdoors, this added protection can be a significant advantage over conventional miniature red dots.
 
ACRO Compatible Footprint
The SRD uses the VictOptics VOD footprint, which is compatible with the increasingly popular ACRO mounting standard. This provides excellent flexibility when selecting mounting solutions for rifles, carbines and compatible optic-ready pistols.
 
A Picatinny riser mount is included in the box, allowing the sight to be mounted directly to Picatinny rails straight away.
 
Side-Loading Battery System
Battery replacement is handled through a convenient side-loading compartment. This allows the CR2032 battery to be changed without removing the optic from the firearm or disturbing the zero.
It's a simple feature, but one that saves considerable time and frustration compared to optics that require removal for battery replacement.
 
Day & Night Vision Settings
The illumination system provides 8 daytime brightness settings along with 1 dedicated night vision mode. This gives shooters plenty of flexibility when adapting to changing light conditions while helping maximise battery life.
 
At the lowest setting, battery life is rated for up to 20,000 hours.
 
Compact Yet Durable Construction
Machined from 6061-T6 aluminium alloy, the SRD remains lightweight while offering impressive durability. The optic is rated to withstand 750G of recoil and is suitable for airguns, airsoft platforms, rimfires and many centrefire rifle applications.
 
The compact dimensions also make it an excellent choice where keeping weight and bulk to a minimum is important.
