This video provides an update on RovyVon's GL4 Pro and introduces the GL5 Pro, focusing on improved mounting systems. The presenter details testing of the new crossbolt mount on a SCAR 16, emphasizing the critical importance of proper torque settings to avoid screw failure and maintain zero. The GL5 Pro's transversely mounted battery is highlighted as a significant durability improvement.

Quick Summary

The RovyVon GL4 Pro's original QD lever had tolerance issues, prompting an upgrade to a more secure crossbolt mounting system. The GL5 Pro introduces a transversely mounted battery for improved recoil durability and a sealed housing that prevents moisture ingress, unlike the older GL4 Pro model.

Frequently Asked Questions

What were the main issues with the original RovyVon GL4 Pro's mounting system?

The original RovyVon GL4 Pro featured a Quick Detach (QD) lever that suffered from tolerance issues, meaning it didn't always securely attach to every Picatinny rail. This inconsistency led many users to request a more reliable mounting solution.

What is the key improvement in the RovyVon GL5 Pro's design?

The RovyVon GL5 Pro's most significant improvement is its transversely mounted battery, positioned perpendicular to the recoil impulse. This design is expected to enhance durability and longevity, especially on firearms with substantial recoil, compared to batteries mounted parallel to the recoil.

What is the recommended torque setting for the RovyVon GL4 Pro's new crossbolt mount?

The presenter advises caution against over-torquing the crossbolt screw. Initial testing suggested that settings between 20-25 in-lbs could lead to screw failure. A range of 15-20 in-lbs, possibly closer to 15 in-lbs, is recommended as the sweet spot for secure mounting without damage.

How does the RovyVon GL5 Pro improve upon the GL4 Pro's sealing and durability?

The GL5 Pro's housing design allows for battery changes without removing the light head, unlike the GL4 Pro. This integrated design helps maintain better sealing against moisture and dust, reducing the risk of internal damage and reliability issues over time.
