I have owned a solid rail extender on my scout squad that extends to rail to a comfortable eye relief for a bit now and haven't been able to shoot much. I have also owned scope mount installed over the chamber. I know a post has addressed rail extenders before but I want to know your personal experience with them and how they size up to say a Sadlak. Like how it holds a zero over time. I like how easy it is to detach from the rifle and secure, with Loctite, to the front rail. The price difference definitely makes it worth a look. Bought mine on amazon by searching 1/2 inch high rail extender. It has a peep sight running through it which helps with bouncing from long shots to close shots via iron sights. I'm happy to hear some alternatives to anything that utilizes the rail mount to secure a scope mount.
