Scopecoat covers come with our Standard and Compact ACOG scopes (since January 2003). See ACOG Accessories model numbers TA62-TA65. We also carry a bikini rubber cap for the 4x32 ACOG, which covers the eyepiece end and fits snug in the objective end. The model number for this is TA52.
How can I tell if I purchased a genuine Trijicon ACOG?
Trijicon® is proud of our line of innovative, quality Advanced Combat Optical Gunsights (ACOG®) and honored that the military, law enforcement organizations as well as recreational shooters around the world depend on our products. We want to make you aware that inferior products (knock-offs) are occasionally advertised for sale to our customers as Trijicon® products.
Genuine Trijicon® ACOG® scopes can be identified by three distinguishing characteristics:
Every ACOG® will be marked with the serial number on the top of the scope, both on the eyepiece and the main housing
All Trijicon® ACOG® scopes have a statement on the left side of the unit indicating that the sight contains tritium
The words “Trijicon® ACOG®” are forged into the main housing and appear as raised letters
We encourage you to buy our products from an authorized Trijicon® dealer to insure that you are getting a genuine Trijicon® product. Please refer to the “Find Retailers” section of our website to find a dealer near you.
Because Trijicon® products contain tritium and many have military applications, exportation outside of the United States is controlled by one or more federal agencies. If you are uncertain whether a particular item is a genuine Trijicon® product, please contact Trijicon® Customer Service at (800) 338-0563 for additional information.
Does bullet weight and/or barrel length effect the reticle bullet drop compensator
and range finding stadia lines?
The real issue is not the bullet weight or barrel length, but muzzle velocity, ballistic coefficient, and the distance from height above bore. The difference in trajectory from bullet to bullet or barrel to barrel is usually less than the MOA thickness of the stadia lines.
The right hand side of the crosshair is blurry. Is this normal?
Yes. The reticle pattern in the ACOG is formed by removing highly reflective metal from a prism mirror. This mirror is at about a 45-degree angle inside the gun sight. This means that the left side of the reticle is closer to the eye than the center of the reticle and the right side of the reticle is further from the eye. The result- the right side of the reticle is focused beyond infinity which can cause distortion on the right side of the reticle. The perceived distortion will be more or less depending on an individual's eyesight. The left side of the reticle is unaffected because the human eye has no difficulty focusing on a closer object. This in no way detracts from the performance of the scope. The image of the target area is not affected. Only the right hand side horizontal reticle line is blurry. This construction is required to achieve a parallax free vertical center of the scope, which allows the built in ranging on the reticle pattern.
I can’t get my ACOG to zero on my AR15. What could be the problem?
Our ACOG scopes are set at 100 meters when they leave the factory. If you cannot get the scope to zero, check to see if the scope is mounted all the way in to the handle. Sometimes a little extra pressure is needed to make sure the scope is completely touching the base of the handle.
Can I change the reticle pattern in my ACOG?
The reticle pattern can be changed, however, this requires the installation of a new prism assembly into the ACOG scope. Please contact our Customer Service Department Monday through Friday 9:00 AM to 5:00 PM Eastern Standard Time for information on options, pricing, and turn-around time.
How far under water was the TA01NSN ACOG tested?
The MILSPEC testing standard used for the SOPMOD, in which the TA01NSN, was tested is (MIL-STD-810E). For leakage testing “all optics and other electrical devices were subjected to waterproof testing to 70 feet to determine device capabilities”. Seventy feet is approximately 2 atmospheres.
How do I use an ACOG on my SOCOM II?
Trijicon recommends the TA70 mount when using an ACOG with a M14/M1A type weapon. A TA70 mount can be used on the Springfield Armory SOCOM II if the “Cluster Rail” is replaced with a standard hand guard. Some Compact ACOG models can also be used with the “Cluster Rail” system if it is equipped with the extended rail section. There are several other Trijicon products that can be mounted directly to the “Cluster Rail” of the SOCOM II such as the Reflex, TriPower and AccuPoint. If you would like additional information on this application, please contact Trijicon Customer Service at firstname.lastname@example.org or (800)338-0563.
How do I remove the back up iron sights from my TA01NSN ACOG® in order to mount
the Trijicon RedDot™?
Remove both the front and rear sight in order to properly mount the RedDot™ and to clear the sight picture. The rear sight is factory installed on the ACOG® using two hex bolts and “Red” Loctite® adhesive. In order to remove the sight, you must apply heat to the bolt area. This will loosen the adhesive grip enough so that you can remove the bolts using a standard 7/64 inch hex wrench. Please use caution when applying heat to the rear sight screws. Extreme heat may damage the internal gaskets or lens coatings of the ACOG.
Trijicon recommends using a soldering iron and placing it in the screw socket. Leave the soldering iron on the screw long enough to thoroughly warm up the screw threads, allowing the Loctite to deactivate. Do note that the duration depends on the soldering iron and settings.
For the front sight, first remove the TA51 mount that comes equipped with your scope. Then place the scope in a vice with the windage adjuster (the adjuster on the side of the scope and not the top) facing towards you. When placing the ACOG in the vice, use padding or another soft buffer to minimize surface scratches. Because of the amount of force generated with the use of a vice, caution should be exercised when tightening. Over-tightening the vice may lead to damage to the ACOG housing, adjustment caps or lenses which may result in the loss of the ACOG’s airtight seal.
Once the ACOG has been properly placed in the vice, using a 3/16 nylon punch, tap the front sight away from you and out of the dovetail. Tap at the base of the sight (near where the sight meets the top of the ACOG housing). Do not use excessive force when tapping the front sight otherwise you may damage the sight.
Both the rear and front sights can be reattached to the ACOG if properly removed. Simply screw the rear sight back into place and tap the front sight back into the dovetail groove.
Do the Special Ring Models come with the mount?
No. Because of the fiber optic design, standard one-inch rings can not be used to mount the Compact AGOG scopes. The Special Ring Models will have the top part of a ring integrated into the scope and you may choose from our selection of adapters for the bottom of the ring that will mount on your weapon.
Does the Cerakote™ paint used on Trijicon products have slight variations in color from
one optic to another?
Yes, as with all paint processes, Cerakote is created in batches. One batch can be slightly darker or lighter than another. One batch may have a bit more gloss than the other. This is due to the way the paint is processed and a very slight variation in the mix can cause slight variations in color or gloss.
