## Before you buy

- Users matching a 1-inch scope tube who want a forward-offset mounting position.

## Customer feedback

Customer feedback highlights perceived value, solid construction, secure attachment, scope retention, and alignment. Some customers report that the mount stays put once snugged down, and one account describes maintaining zero after 500 rounds. These experiences are relevant to buyers seeking a stable Picatinny mount, but they do not independently verify the manufacturer's performance claims. The overall rating distribution is mostly five-star, with a smaller share of lower ratings, and does not explain why individual customers rated it as they did.
- Positive themes: Customers describe the mount as well constructed and appreciate its secure attachment.
- Positive themes: Feedback mentions solid scope retention and alignment, including a report of maintaining zero after 500 rounds.
