Aim Sports AR Low Profile Rear Flip Up Sight: Precision, Durability, and Reliability for Your AR-15/M4

For discerning AR-15 and M4 platform owners, the choice of a rear sight is paramount to achieving optimal accuracy and maintaining readiness. Whether you're a competitive shooter, a tactical professional, a firearms enthusiast, or someone building their first rifle, a robust and dependable backup iron sight (BUIS) is an indispensable component of your rifle's optical system. The Aim Sports AR Low Profile Rear Flip Up Sight stands out as an exceptional solution, engineered to deliver both precision and peace of mind. This detailed guide explores how this specific sight enhances your shooting experience, addresses common questions, and solidifies its position as a top-tier choice for your firearm.

Why is a Reliable Rear Sight Essential for Your AR-15/M4?

In the world of modern sporting rifles, optics like red dots and scopes are prevalent. However, these electronic devices can fail due to battery depletion, damage, or extreme environmental conditions. This is where a high-quality backup iron sight becomes not just an accessory, but a critical safety and reliability feature.

• Uninterrupted Performance: Should your primary optic fail, flip-up sights like the Aim Sports model provide an immediate and reliable aiming solution, ensuring you can maintain target acquisition without interruption.
• Co-witnessing Capability: Often used in conjunction with red dot sights, the low-profile design of the Aim Sports sight allows for a "co-witness" setup, where the iron sights are visible through the optic, offering redundancy.
• Versatility in Training: Training with iron sights builds fundamental marksmanship skills that translate to all forms of shooting.
• Regulatory Compliance: In some jurisdictions, firearms must have iron sights as a primary or secondary aiming device, making the Aim Sports sight a compliant and high-performing option.

The Aim Sports AR Low Profile Rear Flip Up Sight is designed specifically to address these needs, offering a blend of robust construction and precise engineering.

Understanding the Aim Sports AR Low Profile Rear Flip Up Sight: Key Features and Benefits

The Aim Sports AR Low Profile Rear Flip Up Sight (UPC: 815879013798) is a testament to thoughtful design and practical application. It integrates several advanced features that directly benefit the shooter.

Dual Aperture System for Varying Engagements

A hallmark of effective iron sights is their adaptability. The Aim Sports rear sight features an A2-style dual aperture system, providing versatility for different shooting scenarios:

• Small Aperture (0.070"): Ideal for precision shooting at longer ranges. The smaller opening reduces glare and allows for a sharper sight picture, crucial for accurate shot placement on distant targets. This aperture is perfect for zeroing your rifle and engaging targets where meticulous aim is required.
• Large Aperture (0.200"): Designed for close-quarters combat (CQC) or rapid target acquisition. The wider opening provides a broader field of view, making it faster to pick up the front sight and engage targets quickly, especially in dynamic environments or low-light conditions.

This dual-aperture capability ensures that your rifle is ready for both detailed long-range engagements and swift, responsive action in close quarters, enhancing your operational flexibility.

Automatic Locking and Posi-Lock Design for Guaranteed Zero

One of the most critical aspects of any flip-up sight is its ability to maintain zero under strenuous conditions. The Aim Sports sight excels in this regard:

• Ball Bearing Pivot Detent: This feature ensures smooth, positive deployment and retraction of the sight. When raised, the sight automatically locks into position with a satisfying click, indicating it's ready for use. This positive engagement is vital for reliability.
• Flip-Up Posi-Lock Design: This proprietary design guarantees that once the sight is deployed and locked, it will hold its zero, even through recoil, drops, or impacts. Shooters can trust that their sight picture will remain consistent, shot after shot, eliminating concerns about shifting point of impact. This level of zero retention is a significant advantage, especially for a backup system.

Precision Windage Adjustments

Accuracy is paramount, and the Aim Sports sight provides precise windage adjustments tailored to the AR platform:

• 0.65 MOA on M-4 type rifles: For carbine-length rifles, each click of adjustment translates to a precise 0.65 Minutes of Angle (MOA) change at 100 yards.
• 0.49 MOA on A-4 type rifles: For longer, rifle-length systems, the adjustment rate is an even finer 0.49 MOA.

This fine level of adjustment allows shooters to meticulously zero their rifle, compensating for environmental factors like wind or optimizing for specific ammunition types. The ability to make such minute adjustments empowers the shooter to achieve maximum precision.

Robust Construction: Aircraft-Grade Aluminum with Black Anodized Finish

Durability is non-negotiable for firearm accessories. The Aim Sports AR Low Profile Rear Flip Up Sight is built to last:

• Frame Material: Aircraft Grade Aluminum: Constructed from high-quality aluminum, known for its exceptional strength-to-weight ratio. This material ensures the sight can withstand the rigors of heavy use, harsh weather, and impacts without compromising structural integrity.
• Color/Finish: Black Anodized: The black anodized finish provides a tough, corrosion-resistant surface that protects the aluminum from scratches, wear, and environmental elements. It also reduces glare, which is crucial for maintaining a clear sight picture in varying lighting conditions. This sleek, matte black finish seamlessly integrates with most AR-15/M4 rifles.

Low Profile and Lightweight Design

One of the primary advantages of this specific sight is its minimalist footprint:

• Style: Low Profile Flip Up: When collapsed, the sight lies incredibly flat against the Picatinny rail, minimizing snag points and preventing interference with other mounted accessories such as optics, lasers, or weapon lights. This is especially beneficial for those running large primary optics or limited rail space.
• Length: 2.50"
• Width: 0.625" Collapsed / 1.75" Deployed
• Weight: 5.0 oz: Its remarkably low weight adds minimal bulk to your rifle, contributing to overall weapon balance and maneuverability without sacrificing durability.

Universal Compatibility with Picatinny/Weaver Rails

The Aim Sports AR Low Profile Rear Flip Up Sight is designed for broad compatibility:

• Mount Type: Picatinny / Weaver: This universal mounting standard ensures that the sight can be easily and securely attached to virtually any AR-15, M4, or other firearm equipped with a standard Mil-Spec Picatinny or Weaver rail. The secure mounting mechanism ensures that the sight remains firmly in place, even under sustained recoil.

Who Can Benefit from the Aim Sports AR Low Profile Rear Flip Up Sight?

This sight is an excellent choice for a wide range of users:

• AR-15/M4 Owners: Anyone with these popular rifle platforms looking for a reliable and precise backup aiming solution.
• Tactical and Home Defense Users: The immediate deployability and robust construction make it ideal for situations where reliability is paramount.
• Sport Shooters and Competitors: Those needing precise adjustments and quick transitions between long-range and close-range targets will appreciate its dual-aperture design and fine MOA adjustments.
• Rifle Builders: An essential component for any new AR-15/M4 build, offering a foundational aiming system.
• Enthusiasts Seeking Upgrades: For those looking to replace less durable or less precise factory sights, the Aim Sports sight offers a significant upgrade in performance and longevity.

How to Install and Zero Your Aim Sports AR Low Profile Rear Flip Up Sight

Installation of the Aim Sports sight is straightforward, requiring minimal tools.

Step-by-Step Installation:

1. Ensure Firearm is Safe: Always verify that your firearm is unloaded and safe before beginning any work.
2. Identify Mounting Location: Choose a suitable position on your rifle's upper receiver Picatinny rail. The rear sight typically mounts as far back as possible on the rail, while still allowing for comfortable eye relief.
3. Loosen Mounting Screw: Use a hex wrench or appropriate tool to loosen the mounting screw on the base of the sight.
4. Slide onto Rail: Slide the sight onto the Picatinny rail until it sits snugly in the desired position.
5. Tighten Mounting Screw: Firmly tighten the mounting screw. Do not overtighten, but ensure it is secure enough to prevent any movement.
6. Check Alignment: Ensure the sight is aligned squarely on the rail and does not wobble.

Zeroing Your Sight:

Zeroing is the process of aligning your sights so that the point of aim matches the point of impact at a specific distance.

1. Establish Zeroing Distance: For AR-15/M4 platforms, common zeroing distances are 25 yards/meters, 50 yards/meters, or 100 yards/meters, depending on your intended use. A 50-yard zero is often recommended for a versatile battle sight zero.
2. Use a Stable Rest: Shoot from a bench rest or prone position to eliminate human error during the zeroing process.
3. Fire a Group: Fire a three or five-shot group at your target.
4. Analyze Point of Impact: Observe where your shots are hitting relative to your aim point.
5. Adjust Windage: Use the windage adjustment knob on the Aim Sports rear sight to move your point of impact horizontally. Remember, to move the point of impact left, adjust the sight to the left; to move the point of impact right, adjust the sight to the right. Refer to the specific MOA adjustments (0.65 MOA for M4, 0.49 MOA for A4) to calculate how many clicks are needed.
6. Verify Zero: Fire another group to confirm your adjustments. Repeat the process until your point of aim matches your point of impact.

Proper zeroing ensures that your Aim Sports AR Low Profile Rear Flip Up Sight is ready to perform when you need it most.

Maintaining Your Aim Sports Rear Sight

While designed for durability, a few simple maintenance steps will ensure the longevity and optimal performance of your Aim Sports sight:

• Regular Cleaning: After each range session or exposure to dirt/debris, wipe down the sight with a clean cloth. Use a soft brush for any stubborn grime in the mechanisms.
• Lubrication (Sparing): Occasionally, a tiny drop of light gun oil on the pivot points can ensure smooth operation of the flip-up mechanism. Avoid over-lubricating, as it can attract dust.
• Inspect for Damage: Periodically check the sight for any signs of damage, loose screws, or unusual wear. Address any issues promptly.
• Storage: Store your rifle and accessories in a clean, dry environment to prevent corrosion.

By following these simple guidelines, your Aim Sports AR Low Profile Rear Flip Up Sight will provide years of reliable service.
