Q: What makes the M1776 different?
A: We are “iron sight guys” and appreciate the beauty of executing a perfect rifle shot. That means having perfect sight alignment, trigger control and follow through. The core of the M1776 enables the shooter to achieve perfect sight alignment instinctively, without conscious thought. Perfect sight alignment is achieved by simply putting the M1776 globe inside the aperture of your rear sight, “put the circle in the circle” if you will. The human brain is very good at recognizing concentric forms and it does so at very high speeds. As we often note, teaching and understanding perfect sight alignment is now much quicker and easier. That makes you a better, more efficient shooter and or teacher.
Q: Why is the globe so big? (30mm)
A: That is a common question and the short answer is the 30mm globe produces extremely quick target acquisition and a full field of view at the target. You cannot appreciate the M1776 until you get it on your rifle and “see” it. The sight picture is free from any visual obstruction unlike a standard A2 iron sight/post-rabbit ear style. The intended target is fully exposed and you are able to see above, below, left and right of the intended target. You will not only know that you are on target, but will also be able to pinpoint where on your target you are. This is particularly important for tactical and law enforcement applications.
Q: Do I need any batteries or tools?
A: No, on both accounts !
Q: Will the 30mm globe “fit” inside my rear aperture while aiming?
A: Yes, with normal eye relief behind the rear sight you will be able to see the full globe circumference inside your rear aperture. We recommend using a standard US issue “short range” aperture with an approximate inside diameter of .22 inches.
Q: How do you mount the M1776?
A: The M1776 attaches to any picattiny rail system using the quick detach lever system.
Q: I use a fixed rear sight with no elevation adjustment, will the M1776 be compatible with my rear sight?
A: The M1776 is engineered to be at or near the mid point of its 40 MOA elevation adjustment range when using a fixed rear sight where the center of the aperture is 1.42″ above the receiver. Most fixed rear sights are manufactured to approximate the height of an A2 rear sight or approximately 1.42″. See compatibility measurements listed on the Details /Technical Specs page.
Q: If I use a railed gas block set up, what height does my gas block need to be to use the M1776?
A: The M1776 is designed for use on same plane mounting systems so we recommend using a “tall” gas block that is at or near receiver height. There is 40 MOA of elevation adjustment built into the M1776 which will accommodate differences in the manufacturing tolerances for gas blocks.
Q: Can I co-witness the M1776 with my reflex sight?
A: Yes, you can mount the M1776 forward on a quad rail or gas block, turn off your reflex sight and use it as a rear sight in conjunction with the M1776. To zero the M1776, turn the reflex sight on and adjust the elevation on the M1776 to match the plane of the dot in your reflex system, then turn the reflex sight OFF.
Q: Can I use the M1776 as a single plane sight?
A: Yes, you may use the M1776 mounted on a railed gas block or quad rail without the use of a rear sight. You should zero the rifle after establishing your normal cheek weld on the rifle stock. Maintaining a consistent cheek weld during shot execution will insure short range accuracy and effectiveness.
Q: How do I adjust the elevation? Is there any windage adjustment in the M1776?
A: To adjust the elevation, loosen the thumbscrew on the sight base two full turns. Then rotate the globe to the desired elevation and tighten the thumbscrew. Each 180 degree rotation approximates one (1) MOA using a 20″ barrel. Windage adjustments must be made with your rear sight.
Q: How many lenses come with the M1776?
A: Each complete sight is delivered with one lens in your choice of size and color fiber optic rod. Fiber optics are offered in red, green and amber with the aiming reference sized at .030″, .040″ & .060″ in diameter. Additional lenses may be ordered and shipped with your sight. (Introductory offer comes with 3 lenses in your choice of color)
Q: What size lens/fiber optic should I order?
A: The .040″ dot is a good all-around size for most shooters. If you are engaging larger targets at shorter distances, the .060″ diameter dot will also work well. For longer distances, the smaller diameter dot will “cover” a smaller area of the target. Color is a personal preference as some people see red better than green or visa versa. Amber is also popular when shooting with certain backgrounds.
Q: How does the fiber optic rod work?
A: The Fiber Optic gathers all ambient light and illuminates the rod creating the contrast or aiming dot. In dark scenarios, a flashlight accessory will also illuminate the fiber optic.
Q: If I broke the lens, can I still use the M1776?
A: Yes, while it only takes about 30 seconds to replace the lens, you may still engage targets by centering your intended target inside the globe. If you break the fiber optic rod, the “dot” will still illuminate.
Q: Can the thumbscrew back out of position?
A: We coat the thumbscrew threads with purple loctite to inhibit any unwanted rotation. As with any rifle accessory, we recommend you check the tightness of the thumbscrew as part of your normal routine.
Q: How do I zero the rifle using the M1776?
A: We recommend bore sighting the rifle first at 25 yards as follows: ( ensure your firearm is unloaded )
- separate the upper from the lower receiver ( AR platform )
- remove the bolt carrier
- stabilize the upper in a rest and re-position the upper until the bore line is centered on your intended target
- without moving the upper, look through the sights and adjust the rear and or front sight until they are aligned on the target.
- when both the bore and the sights are lined up on target, you are now “bore sighted” at 25 yards
- After insuring a 25 yard zero, then adjust your elevation to your desired yardage zero. We like a 100 yard zeroes !
Q: How long does it take to change lenses?
A: It takes approximately 30 to 45 seconds to change lenses.
Q: How do I change lenses?
A: First, look for the “tik” mark on the face of the globe. That side of the globe has a chamfered inside edge that allows the lens to enter and exit. (there is only one-way in & one way out). Take two thumbs and push evenly around the circumference of the lens toward the “tik” mark side of the globe being careful not to engage the fiber optic rod. Continue to push the lens out evenly around the circumference until the lens exits the globe. Because the machining tolerances between the globe and lens are precise, you cannot remove the lens without evenly pushing on all “clock” positions.
To replace, push the new lens inward from the entry/exit side of the globe using both thumbs until the lens is centered in the channel that is milled into the inner circumference of the globe. Again, push evenly around all “clock” positions. You will feel a “stop” when centered. When properly inserted, you can see a consistent distance between the lens and the outer edges of the globe.
Q: Will the lens pop out during recoil?
A: No, when the lens is properly installed it will not be dislodged during recoil.
Q: How do I keep track of my elevation setting?
A: Much like keeping track of the rear sight elevation on a AR15, we recommend counting the number of full (or half) revolutions from the bottom.
