HIVIZ Spark II Fiber Optic Shotgun Sight – Universal Front Sight for Shotguns – Bright & Durable Replacement Bead

Good value. Comes with all the thread sizes you’ll need. It is the right size; NOT too small. I put it on a cheap single shot Turkish 20 gauge, replacing the brass bead. Big improvement, much more visible. I accidentally broke the bugle shaped tip off of the light pipe. Looks much better and works just fine. If I get another one for another project, I’ll take an exacto knife to it and loose the odd looking bugle part. You do need some loctite

I have used this style shotgun sight before. Has always done excellen job. Good choice for a turkey shotgun.

It's small , yes, but if you mount your weapon light at 6 or 9 , so that some of the flood hits the sight, it's perfect in the dark . The small size becomes an advantage because it doesn't distract your eyes from the target . It's not something you're gonna squint at to see. It's comparable to a 4moa RDS on an 18.5" barrel .

It was very easy to install, I found a video on YouTube from the manufacturer on how to install it. If you don't feel comfortable installing it, go to a gunsmith but don't blame lack of experience in working on your own firearms or not being able to follow simple instructions on the sight or the manufacturer.

Works well and functions as I needed, this was a replacement for the HIVIZ snap on sight, which was entirely too SMALL. but this thing fits the bill.

Thought this would be a screw in replacement for an SKS. Nope, way too small.

On my Mossberg 940PT it was literally a 5 minute install and that because I had to make sure the threads were clean. On this specific it goes in with a Quater turn before proper alignment, no need for grinding. Also I didn't follow the instructions of installing the post with loctite then wait 2 hours.... I initially screwed the post to the sight and just test fitted to the barrel and it was almost there(1/4 of rotation before alignment), so I just put blue loctite on post screwed it to the sight the put loctite to the post then proceeded to screw one whole piece to the barrel turnred 1/4 turn and DONE!.... best $8 spent on my PT!!

I bought this because the universal fit. Unfortunately the threads were to long and there was no way of properly screwing it into the gun. Besides that the sight itself is not very visible. The plastic does not catch light and illuminate well making it harder to see then the bead sight that came with my gun.
