PA makes some good quality stuff, but read up on the auto on/off feature. There are some complaints of how it works in low light situations.
I don't know if PA & Bushnells come out of the same factory, they're both clones of the same optic so yea, they're gonna look similar.
There's another thread about someone's TRS-25 lens flying off. If that happened to me, I'd look at another optic. But the design is pretty solid, even the $20 Redfields seem to be pretty tough. I took a chance on one of those and stuck it on my Beretta 9mm Storm carbine and it's held up well so far, which is more than I can say for my Sightmark Ultra Shot Plus sights.
I'm really disappointed in the Sightmarks, they're the ones with the digital switches. First one I bought runs great, on a 7.62x39 carbine so it sees some recoil. very clear optics for the price. So I bought two more for ARs and both of those would shut off under recoil. Which probably wouldn't be that big of an issue if they were mechanical switches, but with the digital switch when it's off, it's off. Has to manually be turned back on. So they're on rimfire rifles, but if they act up again they're in the trash if they can't perform as well as a $20 Redfield.
