The mount holds zero perfectly on my 223 wylde hunting rifle. Sighted in my optic. Got these for my savage 110 ba stealth in 338 lapua magnum to mount a nikon black fx1000.

It's about as sturdy as you can get. The finish is satin-like which is cool. It is machined well and is made a very good alloy.

Spray the mount down with some brake cleaner and use some anti-seize on the bolts. The base uses torx screws and has a square post, to lock securely into the pica-tinny rail.

Looks fantastic. Will update if issues after zero. Amazon has the best price, and for the money you can not beat it.

Creedmoor rifle. Perfect height for a b5 bravo stock. No problems after 120 rounds. Looks great on the rifle.
