Definitely a great price and brand new. Polymer/rubber encasing. Exactly what was expected, light weight and durable. Magpul gear is always great for anyone, doing a build.
They are rugged, solid, durable and take up minimal room.
I WILL buy these sights again!
My only caution is on the side of the upper. My Mlok set up doesn't allow the front sight to completely deploy all the time but it's my fault and a light touch and it deploys just fine even with my mess up. When I've taken the sight back off it works fine. It's just my spacing issue.
So make sure your future accessories don't enter fear with the sight.
A must have for quality fold down sights.
spring up sight
good look and feel, fit and finish
slightly difficult to depress aperture
A friend of mine said his cheap brand flip up sights had weak springs and would flip up on their own every time they fired. That is not the case with these sights. They say down until I flip the levers myself.
