Description:

An Enhanced Adapter Plate for Your Optics Mounting System

The V4 DEFENDER OPTIC MOUNTING PLATE FOR GLOCK MOS is the solution to ensuring your red-dot-equipped handgun performs at its best.

The weakest link in your red-dot-equipped handgun is the mounting plate between the optic and your pistol slide. If this critical component isn't designed correctly, then your entire system won't work as designed. The C&H Precision V4 Defender series optic mounting plates are designed to address the critical flaws encountered in most plates, and they ensure that your gun performs as intended.

Each C&H Precision V4 Defender Optic Mounting Plate designed for use on Glock® pistols improves two key elements of optics mounting: hardware and optic protection. The plates feature the company's patent-pending T-Nuts and Torx screws, which are made from stainless steel and are replaceable without having to toss the entire plate.

Compatibility

The V4 Defender Optics Mounting Plate is available for the following Glock® models: 17, 19, 34, 35, 40, and 41. Also included on these C&H V4 Defender Optics Mounting Plates is the company's unique Defender Window. This incorporates a proprietary polymer that's resistant to impact and provides an extra protective window at the front of your red-dot sight.

Not only does this window protect your optic from the elements, it also provides a barrier that prevents you from smudging your lens while manipulating a handgun slide.

Optic Fits

  • Holosun 407
  • Holosun 507
  • Holosun 508

TO ENSURE THE LONGEVITY OF THIS PRODUCT, IT’S IMPORTANT TO USE IT WITH CARE AND IN A RESPONSIBLE MANNER.

The Defender was not made for the G40; however, many customers have purchased the Defender and made a small modification that allowed it to work extremely well with the G40. Please note that Defender plates partially wrap the top of the slide and do not fit large frame Glock pistols, i.e., G21 and all pistols of similar width.



Top takeaways

  1. The C&H Precision V4 Defender Optic Mounting Plate is designed to enhance the connection between a red-dot optic and Glock pistols, improving system performance.
  2. It features patent-pending T-Nuts and Torx screws made of stainless steel, which are replaceable, and a unique Defender Window for lens protection.
  3. Compatible with a range of Glock models and Holosun optics, including the Holosun 508, 407, and 507.
