DI Optical is a Korean company with several business units in the USA. Initially, the company specialized in manufacturing OEM products but has entered the market as a single player in 1990. After nearly 30 years of constant development and technological advancement, DI Optical is one of the leading Asian companies in the industry that specializes in the manufacture of heavy-duty red dot optics for small arms and machine guns. So far, the company has made great strides like becoming NATO supplier of machine gun sights and partnering up with many renowned optical brands like Bushnell and Tasco. Having engineered and patented products that have convinced the U.S. Department of Defence and their FCT program, among others, DI Optical is now expanding their presence into the civilian market.
DI Optical has created a couple of red dot sights specifically for the sport shooters and hunters. They are shockproof, intended to be fitted on commercial rifles and most of them come with a built-in Picatinny mount. All DI Optical red dot sights are CNC-machined from 6061-T6 aluminum, ensuring that they are very durable but won’t add unnecessary weight to your rifle set-up. The housing and crystal clear red dot lens are reinforced with various scratch-resistant coatings.
Fog and waterproofed with dry Nitrogen gas, DI Optical products can be used in extreme weather situations and won’t fail. They are made to withstand strong recoil and each product made for everyday user fulfills the features needed on both tactical and hunting environments.
Note that although these red dot sights are affordably priced, they meet the stringent standards that are implemented at this largely law enforcement and military-oriented manufacturer.
DI Optical SP1 is a small tube red dot sight the Korean company created for the civilian market. Don’t let the compact size and affordable size of this entry-level dot sight fool you. SP1 is a highly capable precision aiming solution that can handle everything you throw its way. The brand is known for producing robust red dot sights and SP1 is no exception. Like all their products, this unit has been torture tested under extreme conditions and has passed with flying colors.
The compact SP1 dot is made of rugged construction in a classic tube style that can be used not only with hunting but also tactical applications. The windage and elevation adjustment guarantee perfect alignment with your weapon, making sure you will hit the target every single time. The 22-millimeter lens is multicoated for maximum image clarity and topped-off with a protective scratch-resistant varnish. With this little device, users get a virtually unlimited eye relief and faster target acquisition thanks to the generously wide field of view.
The LED red dot illumination is manually controlled by a single button. It has 12 brightness intensity settings, 10 levels for daytime use and 2 that are night vision compatible. The red dot is powered by a single CR2032 battery that will last up to 5000 hours when used on the medium brightness level. The battery is top-mounted for convenience and quick access.
Customers can choose between two model variants. The first one features a 30 MOA ring with a crisp 1 MOA dot in the center. The second option offers a simple 1 MOA dot without a ring.
DI Optical SP1 is a compact unit that can be fitted on nearly any 5-56.millimeter rifle platform. The detachable screw-in mount for Picatinny rails takes up only 38 millimeters or rail pace (about 1.5 inches). The easily removable 9-millimeter spacer only adds to SP1’s already impressive versatility of use. Made for heavy duty, this small tube red dot sight will operate without a hitch anywhere from -32 degrees to +71 degrees Celsius (approximately from -25.6 to 160 Fahrenheit). This red dot is waterproof, purged with dry Nitrogen gas and can be immersed into 8 meters of depth (16 feet) without a risk. Weighing only 186 grams with the mount attached, this red dot is a perfect solution for any hunter or tactical shooter who doesn’t want to compromise top-notch optical performance for smaller mass. DI Optical S1 can do both.
