Works great, holds zero - Sniper Grunt 4x20 Compact Rifle Scope w/AR Carry Handle Mount

This works really well. I mean it's better than the original ones and looks just like them. It holds zero really well, glass is clear, has as good if not better eye relief than the original ones from 20+ years ago. I mean, yeah it's not like modern scopes eye relief but you have to realize this is based on older technology and as far as it goes I think they've done about the best job that you can with it plus, it's illuminated. I have no complaints. It's perfect for your retro build.
