Good evening to all,

We have a family house in the desert a couple of hours away from our home. While we use it mostly for recreation, it also serves as a place where we can go to be safe in crazy times. We spent the first 9 months of the pandemic up there which allowed us to escape the crazy mayhem going on down below. During this time I was able to bring everything I need up there to keep safe, but I began to think about assembling a small collection of defensive arms to leave there, stored in a safe, that would allow us to leave immediately if need and be protected once we got there. I wanted good, quality arms, but not things that would break the bank.

I initially put together a basic 16" AR-15. Then I found a cheap Glock 17 to go with the AR. Lastly I found a basic Mossberg 500 to add to the safe. I was happy with everything except for the 500. It had a plain bead sight, which works, but is not optimal. I looked at different sighting system and then found Defender Tactical. They make a simple safety replacement that is made from machined aluminum, incorporates a shallow V, and a white witnessmark for sighting. I guess it is sort of a field expedient express sight. I ordered it on Monday and had it on Wednesday so no complaints about shipping or processing. Packaging notes that it is made in China, so that is one strike for me.

The initial impression of the sight is that it is well made, much easier to use as a safety than the factory part, and does provide a much better sighting reference than just the bead. Installation is simple and everything was done in less than five minutes. My safety sight came with a new hex-head screw with lock washer (much easier to install) an extra safety ball bearing in case you lose the factory one, and a taller and wider brass bead for the front end. The whole kit was about 30 bucks shipped.

The safety sight does sit significantly higher than the factory part it replaced, but has rounded edges and does not seem like it will snag or get caught on things. I was fired up to go test it this weekend, but we have had continuous rain for the past couple of weeks and it has flooded out the road to my close shooting spot. I will update once I get a chance to shoot it, but so for is looks like a uncomplicated, affordable option for improving a basic Mossberg system while retaining the simple and affordable aspects of the system.

Here are some pictures for reference:

I did. It all went together great and I am eager to shoot it.
 
Ecvmatt I just ordered the safety site and bead . I was wondering if you had the chance to shoot with the new safety and bead yet?And how it went? Thanks Bob
 
If you like it that is all that matters.

But a common complaint with the safety position of Mossberg's is that they can easily be bumped and moved to the fire position without the user being aware. It happens quite often. In fact, they break often enough that many guys replace them with available steel safety buttons. Sometimes before, sometimes after they break.

The Mossberg 590 took the basic 500 design and improved the 500's shortcomings. A steel safety button was part of that upgrade. I wouldn't have done it. I'm minute of paper plate at 50 yards with slugs with a basic bead front sight.

That's a negative. The 590A1 has the steel safety, regular 590s do not, I own two of them. But as he replaced plastic with aluminium, that's an improvement, if the plastic ones tend to break (not that either of mine have so far, or his apparently).
 
I got rained out last weekend, but am on for this weekend. I will get a chance to wring it out and will report back.
 
Weather is a go and the shotgun+ammo are loaded in the truck. I will report back on Sunday with some observations.
 
Well here is an update on the sight.

The bottom line is that it does provide a basic aiming point, is aligned to the big bead they sell, but might not be very precise. I had three other people from 17 to 54 y/o try the sight as well.

Here is a summary of our impressions:

In all fairness this sight was developed for the Shockwave and meant to be used at arm's length. When we extend our arms and looked at the sight, it is clear and functions like the rear sight on a rifle or shotgun barrel. When we shouldered the shotgun and the sight moves closer to the eye it becomes blurry and the white stripe serves more as a crude reference point than an aiming device. The good is that when you put the bead on top of the white dash you get well centered, POA hits. We only shot out to 15 yards and only used target loads and buckshot. We were planning on shooting some slugs this morning before we came home but the wind picked up and surrounding desert became a dust bowl. I guess that will be for next time.

As a safety it works great and is a notable improvement over the plastic safety it replaced.

For now, I am satisfied that the sight will serve in its intended role. It is unobtrusive, generally works, and is cost effective for my particular need. I think a nice expansion might be the same concept, but drilled to fit the existing holes in the receiver. Moving the sight forward might allow for a better sight picture.

Shooting slugs the next time will determine if I keep this as is or continue to look for another option.

I hope this helps,

Matt
