Great scope if you mount it correctly - Falke CS 4x20mm Ballistic Reticle Prismatic Red Dot Sight

Overall this scope is recommended if you follow correct mounting procedures that all scopes need to take into account. There is no separate recoil lug and even if it did you need to follow correct installation procedures. This mount uses the cross bolt as the recoil lug. It is round with one side machined flat and faces forward against the lug to resist recoil shifting. After adjusting the clamp pressure set the sight on the rail, push firmly forward, if you can, and close the quick-release. I have never noticed sight movement POI shift on different rifles. The build quality is excellent on these compact lightweight prisms. Initially, you must determine your 'length of pull' and scope position on the rail to correctly determine 'eye relief' to get a full picture. Prisms have a shorter eye relief and they are often positioned all the way back on the receiver.
