1st sight died quickly, #2 okay so far - TruGlo Open Red/Green Reflex Sight, Illum. Multi-Reticle

I have this sight mounted to a Mossberg semi-automatic shotgun and it is great. Ease of mounting was super (blue thread lock). Brightness, multi-reticles and 2 colors is impressive. It appears well maid and is highly rated. I fit the pattern that I saw before I purchased - occasional severe failure. True I am using the sight in a harsh environment but it is advertised among the sights suitable for shotguns, rifles and black powder applications on the Truglo website. Among the specific bullet points for this unit is *water and shock resistant. As I sighted the first unit in (using slugs) the glass viewer was knocked loose in its frame and chipped in two locations. OP asked that I work with the mfgr. as the unit had been mounted and used. They authorized a return and in a reasonable amount of time with two calls from me, a new unit was shipped to me. The company requested a $12.50 S/H fee so with my postage, tracking and insurance to them I was out $20 for a clearly defective unit. I sighted that unit in quickly and cycled about 50 rounds of buck, and smaller shot in 2 3/4 and 3" shells and the sight stayed together and held zero. I'm happy overall THOUGH I wish that I did not have to pay for the replacement of defective goods. Next trip shooting I WILL be sure to pick up some slugs just to be sure the sight is up to the advertised tasks. If it holds up it is one good sight for the money if not I will not be requesting a third version of the same unit. Time will tell.
Pros: options for price
Cons: structural failure quickly on 1st sight
