Excellent, flexible combination - EOTech HOLOgraphic Sight 557 w/ G23 3x FTS Magnifier Weapon Sight System w/ FREE ScopeCoat Protective Covers and AA batteries

This is a really excellent combination for going from CQB to mid range accurately and quickly. Well-made. Side-located brightness buttons are a real advantage for this HWS/Magnifier combo because, as with any HWS, an overly bright dot will affect accuracy, so you'll need to be able to quickly change brightness to suit lighting conditions and background. The BDC reticle on the 557 is marginally useful, and then only with the magnifier.

Only complaint - comes set up to flip to the right. In that position, it's harder for a right-handed shooter to hit the flip release, and on that left side ejected cartridges hit the magnifier (leaves marks - don't know if it will actually damage the magnifier. Mine hasn't yet). The device can be changed easily to flip to the left, optimal for a right-handed shooter, but the magnifier sight base release lever position will force the HWS one notch farther forward on the rail. Not a functional problem, just changes the cosmetics a little.

Overall, I really like this system.
Pros: High quality, accurate, functional
Cons: Magnifier base attachment
