Reflex Sights

SIG Romeo 5 for your shotgun. Use the taller mount that cone# in the box and you will still be able to use the factory sights beneath the dot sight. Hi/low option. Dot high, irons low.

That top mounted battery option is huge. That’s the difference between a Burris FastFire 2 and 3. For a little more $$$ you can get a FastFire 3 used. Have one on my S&W 44 mag and it’s been great. But for the money the Zulisy looks good. There’s also an adapter ( Speedbead) made that goes between the stock and receiver. . I might look into this for my Rem 1100.

Never heard of em and the price tells me it's likely garbage. There are a few optics that are passable going for around $150 but for use beyond that of fun on the range a quality optic will run you over $200. Duty grade stuff over $300.
Holosun has pretty much become the go to for red dots.
If you can't swing that amount of money right now my advice would ve to try and find someone that has a shotgun equipped with an optic that will let you try it so you can see if it's even something you want to invest in.
If so take tge $110 that this thing would cost and put it in your savings account and put in additional amounts as you can then get something with a good track record.

Internet reviews mean absolutely nothing, most of them are done by bots on behalf of the company.

I’m 100% serious about the Romeo 5 on a shotty. I have one on my 12 gauge and the dot is nearly nuclear detonation proof. And the price for the SIgg isn’t much more than the air soft grade dot posted up top.
