Red dots on pistols are the bee’s knees these days, everyone is doing it. There are a few different ways to mount a red dot on your pistol. You can have your slide milled to accept one of the various pistol red dots on the market. You can turn your gun into a space gat by using a frame mounted red dot system like the 6 Second Mount from ALG Defense, this method requires a custom holster and you do lose your iron sights however. Or you can use an adapter that mounts to the rear sight dovetail with no milling needed. Or you can just use your pistol’s iron sights like people have been doing before newfangled red dots were invented.
Dueck Defense are the folks behind the RBU sight bases that feature integrated sights built into them. Why have iron sights on your sight base? With some red dot pistol setups you’ll no longer have iron sights or they’ll be blocked. With the RBU sight base if your optic dies you’ll still have iron sights. Another reason is to help with faster target acquisition. It can be easy to lose the dot when you’re aiming, the integrated sight on the RBU can help make it easier to acquire the dot. The RBU bases are made in the USA and require no gunsmithing, they mount right onto the rear sight dovetail. Dueck Defense’s first RBU base was for the RMR sight, they now have one that fits the Leupold Delta Point Pro Red Dot for both the Glock and S&W M&P. They retail for $129.95 over at dueckdefense.com.
