Smartclip Two-Piece Adapter for Liemke (M43x0.75)

About Smartclip

Smartclip is a Slovenian company known for its manufacture of adapters for clip-on devices, noted for their robust construction and superior finish. The adapters feature a distinctive lever that closes inward toward the adapter body, unlike many competitors' adapters where the lever shifts from the rear (loose) to the front (fixed). Hunters often detach the clip-on from the scope to swiftly scan the area. In the dark, particularly when excited by the sounds of nearby wildlife, there's a risk of quickly bringing the device close to the face, potentially poking the eye or surrounding skin with the lever in the loose position. Ludwig Dvojmoč, the company’s founder, developed the unique lever design in response to several injuries caused by traditional lever mechanisms, effectively eliminating the risk of such mishaps.

Ludwig Dvojmoč has experience working with well-known companies in the sports optics industry, such as Zeiss and Aimpoint. He played a pivotal role in establishing the Slovenian chapter of the International Practical Shooting Confederation (IPSC) and contributed to the amendment of several rules in the competition overall.

About the Smartclip Two-Piece Adapter for Liemke (M43x0.75)

This two-piece adapter is designed for the front-scope mounted clip-on devices with the Night Pearl mounting standard (M43x0.75). It consists of the Smartclip AS adapter and the Smartclip reducing ring for the Night Pearl mounting standard (M43x0.75).

The AS adapter features the M52x0.75 mounting thread which is often referred to as the Dedal mounting standard. Dedal was the pioneer in producing clip-ons for civilian use, and adapters with this standard were initially tailored for their devices. Nowadays, these adapters are frequently paired with reducing rings or converters to accommodate various mounting standards. When used with devices featuring the M52x0.75 mounting standard, no reducing ring is necessary, making this adapter function as a single unit. However, for devices with different mounting standards, a reducing ring is required, resulting in a two-piece adapter setup. Unlike one-piece adapter solutions, which typically offer limited size options for outer objective diameter, AS adapters provide a comprehensive range, with approximately 99% of all sizes available.

The Smartclip reducing ring for Liemke features an M52x0.75 thread for attachment to the AS adapter on one side and a thread for connection to the Night Pearl mounting standard (M43x0.75) on the other.

What is a reducing ring/converter?

Adapters that serve as a basis for clip-on mounting feature a M52x0.75 thread on one side and a riflescope objective attachment mechanism on the other. If you wish to mount a clip-on with any other thread/bayonet on your riflescope, you have two options. You can either purchase a one-piece solution, which has limited size options, or a two-piece adapter. The two-piece adapter consists of a M52x0.75 thread adapter combined with a suitable reducing ring or converter.

Smartclip adapters – size guide

With Smartclip adapters, the number in the adapter’s name indicates the outer objective diameter of the riflescope that it is designed to fit onto (in millimeters). To ensure you choose the correct adapter, measure the diameter of your riflescope’s objective using calipers (see the image below).

Mounting instructions

Mounting the reducing ring on the adapter

Align the AS adapter with the M52x0.75 thread on the reducing ring. Carefully thread the adapter onto the reducing ring until it is fully tightened. Use the provided wrench to securely fix it in place.

Mounting a device with the Night Pearl mounting standard (M43x0.75) on the reducing ring

Thread the counter-nut onto the Night Pearl mounting thread (M43x0.75) of the clip-on until it reaches the end. Position the reducing ring to align its M43x0.75 thread with the thread on the clip-on. Carefully screw the reducing ring onto the clip-on's thread, stopping just short of fully threading it. Prior to fully tightening the device onto the thread, utilize the counter-nut to adjust the adapter's positioning, ensuring the lever remains easily accessible when the device is mounted on the clip-on.

Mounting the adapter on a riflescope

Start by placing the lever in the open position. Push it away from the adapter body to do this. Next, verify if the adapter fits onto the riflescope's objective. If it doesn't fit properly, you will need to make some adjustments:

1. Unscrew the lock screw, which is positioned perpendicularly to the adjustment screw.
2. Turn the adjustment screw. Rotate it clockwise to tighten or counter-clockwise to loosen, depending on the fit needed.
3. Continuously check if the adapter can be placed on the objective while you make slight adjustments to the screw. When the adapter is placed on the objective, try closing the lever slowly – the resistance should be just right, not too loose and not overly tight. Keep adjusting the screw until the lever secures into position with just enough resistance. Be cautious: attempting to close the lever on an overtightened adapter may break the lens of the riflescope! Check the fit by firmly moving the adapter to ensure it is securely attached.
4. Once you achieve the desired fit, secure the adjustments by screwing the lock screw back into place.
