There are many variables that come in to play when searching for a premium set of scope rings. This quest is one that must not be overlooked. After all an optic is the shooter’s connection to the target and rings are the optic’s connection to the weapon. First, we need to define what makes a scope ring “premium”. There are many good options on the market but are there really any “great” options and is there anything worthy of being called "premium"? Enter the American Precision Arms Tru-Loc Scope Rings.
As competitive shooters and serious hunters we require flawless function and form from our equipment but what exactly does that mean for a scope ring? Let's break it down into several categories and see how the APA rings stack up.
Weight and Strength. Let's talk materials.
99% of rings are made from steel, aluminum, or cast metal. We can go ahead and eliminate casted products from the premium category, not out of snobbery but for the well-known fact that there is always a potential for unseen voids or weaknesses in a cast or MIM (mold injected metal) product.
Next is steel. Steel is a great option for scope rings, especially stainless steel. It's certainly strong enough but it does come at a price. Because steel is so heavy, many shooters avoid it because of its added weight in an awkward area. It tends to bring an unwanted dis-balance and top-heaviness to the rifle. Some also fear of potential scope damage when utilizing steel scope rings.
This leaves Aluminum. It is important to note that not all aluminum is created equal. The majority of aluminum alloy’s are not up to the task. Most “higher-end” aluminum scope rings are going to use 6061 aluminum, which is often referred to as “aircraft grade”. The reality is that though there are 6061 parts used in aircrafts. It is never used on the wings, turbines, or hull (the important parts where maximum strength is required). Only the highest strength 7075 aluminum is called upon for these tasks. 7075 is nearing 2X the strength of 6061 and is the only alloy found on APA rings.
One thing you can say about the vast majority of latch designs that incorporate with a Picatinny rail is that, “they are all the same.” Whether using a screw, two or three screws, a large cross bolt, or a lever, they all have a latch that comes in from the side and cams on to the under side of the rail. For the most part it works pretty well but it does raise a couple of issues.
The first issue is repeatability. In a perfect world, a shooter should be able to shoot a group, remove the scope and rings from the rail, put it back on in the same slot, tighten it down and shoot in that exact same group. With the standard design this will never happen because the design is torque sensitive. Because the latch cams in from the side, it would have to be torqued down to the precise poundage of the previous mounting to end up in the same spot. Not to mention the stress that may be coming from an out of spec rail. A perfect “return to zero” is simply not feasible with the common design.
The second issue that arises is strength. Gigantic cross bolts and multiple latch screws only look like they are solving the problem but the reality is that the weakness is not in the tightening mechanism. It is in the mechanical mating surface of the latch and its orientation of tension to the receiving mating surface of the rail. To put it simply, the screws and bolts wont break first, the latch will.
The Tru-Loc Latch System
The APA Tru-Loc design is different. Unlike traditional Picatinny latch systems, the Tru-Loc latch doesn’t come from a lateral angle that leaks strength due to the lack of direct tension to the rail. The Tru-Loc latch applies tension directly to the rails mating surface. This answers the two issues that surfaced earlier.
First, It is repeatable. It screws directly perpendicular to the rail’s mating surface. This means it is going to come in to the exact same place every time it’s tightened down. Also, it is NOT torque sensitive. Whether you tighten it to 10 inch pounds or 47.2 inch pounds, it will secure the scope in the same precise location every time. What if the rail is out of spec? With the APA design it won’t matter. It will self-seat to the same orientation that it did the last time it was mounted. Secondly, it applies strength where strength is needed and avoids bulky screws and bolts that don’t address the real issues.
The tolerances on the APA rings are literally held to a higher standard than any other scope ring on the market. The APA Tru-Loc Ring sequences through a quality control process that eliminates any unit with over .0005” of run out. For those that don’t speak this kind of “mathy” language, .0005 = one half of one thousandth of an inch. The relationship between the bottom of the ring base, where it rests on the rail and the center bore or cross-section of the scope tube is extremely important. Remaining with in these tolerances allows the Tru-Loc rings to avoid having matched sets. Any ring, base or cap, will match any other of its like size perfectly.
Ultimately, this means that the optic can be mounted in a completely stress free environment. This also aids the Tru-Loc’s impeccable ability to return to zero. Another benefit of this level of precision is the ability to avoid vague sizes like “low, medium, and tall.” With the APA rings you will be able to choose a height that fits your precise needs as they are labeled with the measurements mentioned earlier.
We have uncovered some simple truths about the APA Tru-Loc Scope Rings. First, well remaining light, sleek, and attractive, the APA rings are among the strongest in the world due to their unique design, premium materials, and un-matched build quality. Next, they possess the ability to return to a finite zero because of engineering geometry’s utilized. We also covered the tolerance standards that the rings are held against being closer to perfection than anything else on the market. Finally, sizing. Say goodbye to ill-defined sizes that don’t give you the information that you need to choose the right ring height. APA Tru-Loc rigs embody the true essence of a “premium product”. Scope rings are a fundamental keystone of a rifle system’s accuracy and should never be skimped on. As mentioned earlier, the optic is the shooter’s connection to the target and the rings are the optic’s connection to the rifle. You can trust that the APA rings will do a better job keeping you on target and standing up to adversity than any other set available to date.
