Good value for extending range. - Firefield 5x Tactical Magnifier for Weapon Sights

I have a few of these 5x magnifiers that I use with the Firefield reflex sights. Unfortunately, the stock mount is about 0.25" too short, so I use a QD riser and a shorter 30mm scope mount to get the right height. It's not perfect, but it's not bad. The accuracy is good with the reflex sight and I can see the bullet holes at roughly 50 yards. If you need something to extend the range of your reflex or red dot sight, this is an affordable solution.
