The bottom crew which help attached to the conversion kit using a smaller crew. This tweak is very clever. I like this innovation.
The top rail has only 1 crew hole. I wish it has 2 crews because I am trying to attach this kit under my AR15 barrel.

The Recover Tactical 20/20 Series GB20 Glass Breaker w/ Optic Mount Attachment is byfar the best attachment that you could add to your 20/20 the quality material is built to last.

This fixes the only problem I had with my setup by putting a strong solid even sight rail supported on both sides. Turned a cool gizmo into a legit weapon upgrade.

I know everyone wants the new drop on AR looking gizmo and great if you want it. But for portability accuracy and just weight reduction. This is the ticket!

This has a perfect fitment and weight. Easily the best accessory you can add to your brace.
Looks very sharp and will definitely do what it’s designed for. Well worth the wait!
What size is the long screw used to secure the GB20 to the 20/20 brace? Looking to replace with a thumbscrew as the M6 Thumb Screw GB835 30mm I used before does not fit. Thanks!

I think I'm missing some context here. Can you clarify your question?
AI replaced the nut & bolt that holds the chassis together. With a round thumb screw, so I don't need to use an Allen key to install or remove the pistol. It's the same length as the stock hardware, so I was wondering if the glass breaker uses different length hardware?
A
I appreciate the thumbnut idea! And I understand the question now. Thanks for clarifying. The GB20 does add a bit of width and thus the bolt is longer to accommodate.

Very confusing. In Q/A sessions, one answer said "The GB20 is not compatible with the original 20/20". Another answer said "The GB20 is compatible with the original 20/20". So is GB20 compatible with the original 20/20 or not? Please clarify for users of original 20/20.
