Most Helpful Positive Review Absolutely Awesome!
I had been looking for months for an 18.5" Security Barrell for my Mossberg Maverick 88. It came with a 28" barrell but I wanted the shorter one for home defense use. Every place. Including Mossberg, was sold out but finally OpticsPlanet came through! Not only was it in stock, but the price was ama...

This product could be great but i wouldn't know. I bought it over three months ago and they wont ship it.

Misleading product description

by Ben, Verified Owner from PA, United States Written on September 22, 2024
Just received the barrel that is supposed to be the blued barrel. Instead it is matte blued and doesn’t match the rest of my gun. It also does not include a sling mounting stud as is shown in the picture. Very disappointed with Optics Planet.

home defense

by Christopher Richard, Verified Owner from PA, United States Written on March 1, 2024
It was what exactly what I was looking for. I had a old Mossberg 500 that I don't use anymore and I wanted to turn it into a home defense shotgun and this barrel worked out perfectly. It's short Lanes it's me maneuver and tight spaces.

by Mossberg Maverick 88 18.5 barrel, from TX, United States Written on August 17, 2023
fit my mossberg maverick 88 6 shot perfectly. came new in box. was exactly what i ordered. swapped out my full size barrel for this 18.5 to make my old shotgun a home defense gun. i got a blues barrel to match existing color and finish and was spot on.

Bad finish

by Brian, Verified Owner from OH, United States Written on July 19, 2023
The blueing on the barrel has a bare spot. I would think Mossbergg would have better quality control than this. Clearly visible so somebody in quality control should have easily caught this. Disappointing for sure.
