Rocky Mountain Bushcraft: REVIEW: Is your Mossberg 500, 590, Maverick 88 or Shockwave shooting high? Defender Tactical's Highball Brass Bead Kit is an affordable and easy fix

Mossberg's 500, 590, Maverick 88 and Shockwave series of pump shotguns are beloved by millions of Americans for home defense, hunting, camping, off-the-gridding, farming and ranching. But there's one problem with them -- they shoot really high from the factory when eqipped with a security length barrel and a bead front site.

The problem is so pervasive that it has long been the practice of firearms instructors and police trainers to advise students with Mossbergs to "aim for the belt" just to hit center mass.

The reason for this is that Mossberg's 18.5" and 20" self defense barrels have a front brass bead that sits lower in the sight plane compared to Mossberg's longer 28" hunting barrels. Mossberg's hunting barrels have a "vent rib" over top of the barrel, which raises the bead to the proper height which allows them to shoot to the point of aim.

To illustrate this, here is a photo of my 28" Mossberg 500 Vent Rib Barrel Hunting Barrel over top of my Mossberg 500 18.5" Security Barrel with the factory brass bead:

So when you are shooting a Mossberg short-barreled defense shotgun, it can be very frustrating to hit what you are aiming at when you are shooting at longer distances, especially when you are shooting slugs.

Remington solved this problem with their 870 series defense shotguns by creating a raised front sight platform for their self defense barrels which shoot to the same point of aim as their hunting barrels:

Unfortunately, Mossberg has still not addressed this issue.

Luckily, the aftermarket has responded to this problem in the form of the XS Big Dot Front Night Sight for Mossberg barrels. The XS Sight is an excellent front sight that corrects the point of aim issue, but it is a lot more expensive ($70 to $90 street price) and more time consuming to install.

Seeing the need for a lower cost, easier to install option, Texas-based company Defender Tactical has come up with a new product called the "Highball Brass Bead" to solve this problem once and for all.

The Bead

The Highball Brass Bead is a taller, thicker brass bead that allows your Mossberg shotgun to shoot to the point of aim. It is super easy to install (check out Defender Tactical's install video) and is quite a bit thicker than the original bead so that it cannot break easily if the gun is accidentally dropped. The street price for the Highball bead is $15.00.

As you can see, the Highball Bead makes up for the lost height from the lack of the vent rib, allowing for the gun to shoot to the point of aim.

The Rear Tang Safety Sight

Although you can buy the Highball Bead by itself, Defender also sent me their Rear Tang Safety Sight to try out with the Highball front bead. You can buy Rear Tang Safety Sight with the Highball Brass Bead as a kit for $25.00.

Manufactured from aircraft grade aluminum, the Rear Tang Safety Sight has a sight line notched into it to act as a rear sight for better sight alignment with the front bead.

It is also shaped to improve upon Mossberg's rather uncomfortable plastic safety switch. The stock plastic safety switch has sharp edges on it which make it uncomfortable to push back and forth.

The Defender Tactical Rear Sight Switch with its higher and smoother profile solves this issue and makes engaging and disengaging the safety much easier. It's also easier to find and manipulate it with your thumb in the dark when under stress compared to the stock plastic safety switch.

In case you're wondering what is protruding from the side of the receiver, it is a Made in the USA Grovtec Swivel Stud for attaching their Quick Detach Single Point Bungee Sling (also made in the USA).

Grovtec's Quick Detach Single Point Bungee Sling has been a great accessory for my Mossberg 500 FLEX Takedown, especially when I have the pistol grip installed. It allows me keep the shotgun firmly and comfortably attached to my body and allows me to go hands free if needed.

It also acts as a poor man's brace to increase accuracy when aiming my shotgun with the pistol grip. Highly rec'd accessory!

Field Testing

Ok, I have the Highball Brass Bead installed, but does it work as advertised?

To test out the Highball Bead, I grabbed my Mossberg 500 FLEX 12 Gauge, installed my 18.5" Security Barrel on it and set up targets at 25 yards and 50 yards. I then shot them with various slugs using both the original bead and the Highball Bead.

I found that the Highball Brass Bead completely eliminated the point of aim issue. Here are the results:

Yes, this target looks like a confusing mess. But that's because a separate wad struck the target after each shot and made a hole similar to a slug going through it, hence all the circles and notes on the target.

But if you look carefully (click on the photo to enlarge it), you can see that with the factory brass bead at 25 yards, the shots were hitting at the top of the chest and slightly right. They were hitting slightly right because using just the front bead (with no rear sight obviously), was causing my windage to be slightly off.

But after installation of the Highball Brass Bead and the Rear Tang Safety Sight, I was putting the slugs right into center mass.

25 Yards using Federal's 1oz Shorty Slugs:

25 Yards using Remington's Slugger "Managed Recoil" 1oz Slugs:

50 Yards using Fiocchi's 7/8oz Low Recoil Slugs:

I absolutely love Fiocchi's 7/8th ounce Low Recoil Slugs. Although they were not as accurate as the Remington Slugger Managed Recoil Slugs in my Mossberg, they are plenty accurate within typical slug distances. But their significant advantage over any other slug I've tried, is that they have very low recoil yet still pack a punch. They are also nearly as light as a 20 Gauge slug. So they are an excellent ultra-light 12 Gauge shell to to throw into a wilderness/backcountry survival kit for bear protection and emergency hunting.

Durability

I saw comments in an online forum wondering if the Defender Highball Brass Bead would break easily due to its taller size. Well, I've had the Highball installed on my Mossberg 500 since May of this year (8 months as the time of this writing). During that time, I have bumped it into a number of hard surfaces while going back and forth from the range without the slightest hint of it bending or breaking.

Despite its taller size, it is much thicker overall than the factory bead. Based on my experience with it so far, I believe it would take a blow hard enough to damage the steel barrel in order to break the Highball bead.

Final Thoughts

Cons? Just one -- the Defender Highball Bead and Rear Safety Sight kit is made in China.

According to the owner of Defender Tactical, he would have had to charge double the price if he made the bead and rear safety sight in the United States. He told me that as much as he would have loved to manufacture it here, he felt that gun owners would not be willing to pay that much for a brass bead and rear safety sight.

I can't argue with him that the culture in America is still "buy whatever is cheapest no matter what evil dictatorship it comes from."

Hopefully in the near future this attitude will change, because every Chinese product we buy goes towards the building of hypersonic missiles that are being pointed at our Navy ships in the Pacific.

Origin of manufacturing aside, the Defender Tactical Highball Brass Bead & Rear Tang Safety Sight kit is well made and does exactly what it is supposed to do at a very affordable price.
