Product installation:
- Depending on what optic you have you will need to find the screws that correlates with your particular optic. There are two special screws for Triji-con RMR. Once you secured the GUM to your slide and found the correct post ( two sets of reinforcing post included) for your optic, go ahead and mount your optic on the post and use the final two longer securing screws to secure your optic to the GUM. 
- It is highly suggested that you have a gunsmith install the GUM and utilize the correct tools for installation.
- Leupold Delta Point* can be mounted but not with reinforced posts to secure 100%
UPDATE: We have confirmed compatibility with Vor-tex Red Dot sights
