Thread: Flip to side red dot magnifiers

So I've been looking more in to getting the Stag 3T and I've been looking at optics to go on it, with the Vortex Strikefire red dot striking my eye because of the price. Pair this with the 3x magnifier that vortex makes and it would seem like a nifty little package on paper but my question is what is YOUR experience with flip to side magnifiers? Are they really that great or are they just another gimmick to sell to tacticool keyboard ninjas?

Would I better suited with a 1-6 power optic? Because my 3-9 seems a little large for the top of a carbine length rifle.
