It’s best to adjust the range focus for the best image and no parallax. Parallax can be seen if the crosshairs move from the point-of-aim, when you shift your eye from side-to-side or up-and-down while looking through the scope. This will effect accuracy at longer ranges. Zoom ring On the TRS-1 you have a Zoom Ring that allows you to adjust the magnification of the scope for differing shooting conditions. The scope is variable from 4X to 16X power. The Mil-Dotbar is set to be 1 mil at 10X on the Zoom Ring. At this position, the Mil-Dot and Mil-Dotbar is 3.6 inches at 100 yards. There is an indent at the 10X setting on the Zoom Ring to aid in finding this position. If your shooting requires the utmost accuracy, it is best to test fire the scope and weapon at various power settings to assure your zero and to see how the magnification effects your shooting accuracy. Sun Shade Helps to prevent glare and improves image in bright sunlight. Use care in screwing sunshade into scope body. Mil-Dotbar™ reticle Millett has developed the Mil-Dotbar™ reticle to assist the shooter in range- finding and hold-over at longer ranges. From the center of the Dot to the Bar is one mil, which is 3.6 inches at 100 yards. The TRS-1, and TRS-2 scopes Mil- Dotbar is set for use at 10 X. On the TRS-1 if you are not on 10 X power you will have to adjust your measurement using the Mil-Dotbar chart below. At 500 yards it’s 18 inches and 36 inches at 1000 yards. This measurement can be used to hold over for bullet drop and for wind and moving targets. The dot is .75 inches in diameter at 100 yards which is also useful as a measuring device. The bar is .20 inches in thickness. By learning to use the Mil-Dotbar reticle, you will be able to judge range and shoot more accurately. See the range chart for more on the measurement of the system. See Chart 4 for a simple method of use of the Mil-Dotbar reticle. A good reference is Use of the TRS scopes and Mil-Dotbar at longer ranges As the TRS scope does not have a turn counter on the elevation turret for keeping track of number of turns adjusted, using the Mil-Dotbar reticle is more important. By sighting in at a longer range and using the hold over measurements of the Mil-Dotbars, the lack of a turn counter is less important. If you sight your rifle in at 200 or 250 yards, it’s possible to get good accuracy out to 600 yards by using the Mil-Dotbars to hold over. For example; a 308 Win with a 168 gr bullet sighted in at 200 Yards is 54 inches low at 500 yards, which is a 3 Mil-Dotbar hold over for dead-on impact. At 600 the drop is 92 inches and 1 mil equals 21.6 inches, so 4 mils equals 86.4 inches. Therefore you need to come up 8 clicks as each click equals .75 inches. 1Mil3.6”.72MOA CHART 1 MIL-DOTBAR VARIABLE SIZE TO RANGE MIL-DOTBAR SCALE Power Setting 100 Yds. 4X 5.8” 6X 5.0” 8X 4.3” 10X 3.6” 12X 3.0” 14X 2.7” 16X 2.5” CHART 2 TRS- 1 SPECIFICATIONS Power: 4X to 16X Length overall Inches: 16.4” Objective lens: 50mm Mount length: 6.8” Field-of-view ft at 100 yards: Weight: 29.5oz High 8 ft.

John Plaster Care of your scope Your Millett TRS scope is designed to give many years of service in the most demanding of conditions, but it does require proper care and treatment. Your scope is waterproof, and will not be harmed by rain, snow and dampness, but the electronics for the illumination, if submerged for any length of time in water may be damaged. It’s best to keep the scope as dry as possible, and wipe any water off the scope and its lenses. Take care of your scope, and it will serve you for a long time. Keep the lenses clean and only wipe with p...
