Its fragile - SIG SAUER Romeo3 Mini Reflex Sight w/Riser, 1x25mm, 3 MOA Red Dot Reticle

Sig makes some great products and has a warranty to back it up. I have to say I am impressed with their customer service and the look, fit, finish, and performance of this sight. With that said, my glass broke after owning this sight less than a week. I had my rifle leaning against the couch, it’s length is less than 24” overall so the sight maybe 14” off the ground, and slid to the floor from an upright position and broke the glass. No scratches or dents on the outer shield yet still broke the glass. Sig replaced it outright but it shouldn’t have broke in the first place. Would not recommend this for a main battesight as you can’t rely on it.
