SR-4C 1-4x RED DOT                            

     

 When mission accomplishment depends on speed and precision the SR-4C raises the bar and the brass ring.

Versatility always seems to come full circle.  Red dot sights have proven to be an indispensable tool for CQB and rapid target acquisition.  Enter the SR‑4C, it integrates the strengths of a red dot sight into a compact, unitized package with the added benefit of a 1-4X range of magnification. The SR-4C features a true 1X power, 4 MOA, daylight visible red dot sight rolled up in a rugged 30mm hard-anodized aluminum body.  The second focal plane red dot can be set at any of 12 pre-programmed intensity settings. The lower four settings are night vision compatible. The SR-4C comes standard with a non-lit, MIL Scale* reticle for ranging and acquiring targets at short distances to 400+ yards and in close quarters conditions.

Matte Black type III is the hardest scope coating in the industry it is scratch proof and chemical proof. This coating can with stand severe abuse, salt fog tests have been conducted internally and externally by outside military testing. Sulfuric acid is the most widely used solution to produce anodized coating, while coatings thicker than 25 μm (0.001") are known as Type III, hardcoat, hard anodizing, or engineered anodizing. Standards for thick sulfuric anodizing are given by MIL-A-8625 Type III, AMS 2469, BS 5599, BS EN 2536 and the obsolete AMS 2468 and DEF STAN 03-26/1.The Matte Black finish is matte black dye.

Cerakote Forest Green*	Cerakote Nut Brown*
Cerakote MIL-Spec Green*	Cerakote Flat Dark Earth*
Cerakote FS Brown Sand*	* Note:  This extends the build time by 2 months Cerakote coatings are formulated for specific applications and technical requirements. Current Cerakote product lines include coatings specifically for firearms, exhaust systems, pistons and high wear applications. In addition, Cerakote is available in a line of ceramic clear coats. If you want to match the color of your scope to your rifle or any other gear, Cerakote is the product for you.

Unlike other scope companies, U.S. Optics allows the customer to customize their scope down to even the color. Whether it is a different color Type III Hard Anodize, or a Cerakote color, we can match the look of your rifle/gear on the scope. Because we are building all the scopes in house, we don\\'t need to mask off the crucial parts, we coat each part before the scope is assembled for a high quality job.

One of the most important parts of a rifle scope is the objective. The objective determines many qualities of the complete optical system. Magnification, exit pupil and light gathering are some of the most critical points. The larger the objective diameter, the more light will be gathered into the optical system. The smaller the objective, the smaller the exit pupil, and the longer the objective, the more magnification is gained.

 

Elevation knobs are one part of a scope that gets used a lot and having a repeatable, durable knob will provide many years of use. Whether you are using the EREK, #1 or #3, all knobs are made of stainless on stainless, or stainless on brass. Each knob is hand lapped to insure exact repeatability and accuracy. All knobs use an encapsulated tungsten ball with a stainless threaded housing so our technicians can adjust the tension for the perfect feel.

 

US#1 2/10 MIL Zeroing

The U.S. #1 Zeroing knob is basically the same type of design as the standard U.S.#1, but it is in a smaller form. This knob is perfect for someone who uses their reticle for hold over\\'s and does not need to be adjusting the knobs frequently.

 

We suggest this to many hunters to try to keep the weight and size down on the scope. There is an aluminum screw on cover to protect the knob as well as keep it from moving during transportation.

 

The windage knob on your scope adjusts for the left and right bullet impact. Made from stainless steel and brass, each windage knob is hand lapped for a perfect thread match between the mating parts. Encapsulated ball detents give the tactile feel that makes for a precision feel.

 

30mm tubes are standard on all U.S. Optics scopes with a choice of either 34 or 35mm tubes for added elevation travel. If you are looking to improve the distances that you are capable of engaging, you may consider the upgraded larger tube diameter. Some people think that the larger tube diameter provides better light transmission, but this is not the case.

 

Parallax becomes very important with the higher magnification scopes and the longer distances that you are shooting. Whether you are using the ERGO objective or the TPAL (turret parallax adjustment), the result of eliminating parallax is the same.

 

Red Illuminated Dot

We offer two different colors for the true daylight visible Dot illumination that will allow the user to contrast with the target. Our push button digital illumination offers 12 positions of intensity from extremely dim to extremely bright. A CR2032 battery powers the module and provides enough power for up to 8,000 hours of use at the lowest setting. With a built in 1 hour auto shut-off, you will not need to replace the battery for some time. Turn on the module by pressing one button, dim or increase intensity by pushing the other two buttons. Once you select the intensity of your choice, you may turn the module off and then when you turn it back on it will resume the previous setting.

 

Illumination of the reticle is useful in situations where the reticle can be obscured by a black background/target. We offer different colors for the illumination that will allow the user to contrast with the target. Our push button digital illumination offers 12 positions of intensity from extremely dim to extremely bright. A CR2032 battery powers the module and provides enough power for up to 100 hours of use. With a built in 1 hour auto shut-off, you will not need to replace the battery for some time. Turn on the module by pressing one button, dim or increase intensity by pushing the other two buttons. Once you select the intensity of your choice, you may turn the module off and then when you turn it back on it will resume the previous setting.

 

Your reticle decision is one that will aid in many points of your scope. If you are choosing MIL, MOA or IPHY we have a reticle for you. Various reticle models have different ranging stadia, line thicknesses and design to aid the operator in hold off\\'s, ranging and fine precision shot placement. If you don\\'t see a reticle that suits your needs, contact us and we can design and build one exactly the way you want it.

Made from 6061-T651 and then Type III hard anodized, the eyepiece housing is as robust as the body and other parts of the scope.

Our rapid focus eyepiece makes adjusting for diopter a quick and simple task. Unlike other scopes, the eyepiece housing stays in place while rotating the eyepiece itself.

Secure your rifle on a tripod to improve accuracy and stability. The Fish Head Ind. mount clamps onto the forend of you rifle so the shooter can remain in mission readiness for long durations of time. Available in Type III black and OD Green hard anodizing. Standard ¼-20" tripod mounting thread in base allows you to use most any tripod on the market.

Keeping your rifle in the same position after every shot is essential for accuracy, the Anti Cant Device aids the shooter in keeping the rifle from canting during repetitive shots. These ACD\\'s are manufactured from 6061-T6 then Type III hard anodized for durability. Screw on cover protects the glass vial from damage during transportation, and during shooting the cap saver on the opposite side allows for storage of the cap. Mounts to all 1913 Picatinney rails in seconds.

Making sure that your rifle maintains the same angle of cant between every shot is key for repetitive shot placement. Our ACD’s (Anti Cant Device) are made with a visible bright yellow liquid and are 1 arc minute in accuracy.
