The Mossberg Security Shotgun Barrel produces a widespread for duty and self-defense use.

Made by Mossberg for use with 12-gauge Mossberg 500 and Maverick 88 *6-shot* shotguns, this barrel transforms either into a tactical-looking workhorse. Law enforcement and civilians will appreciate the wider pellet distribution produced from this barrel, allowing them to land hits on targets more easily and therefore better protect themselves. The shorter 18.5-inch barrel length and fixed cylinder constriction rate are ideal for narrow corridors and close quarters engagements. The barrel additionally features a standoff-style breaching end for easy anchoring of the barrel into a door while setting the optimal firing distance.

Leading by example since 1919, Mossberg continually introduces innovative, dependable firearm designs that become the new standard to beat. Though most famous for their array of specialized shotguns, this company also produces a large number of other firearms, including rifles and pistols. Mossberg strives to meet every shooter's needs with top-quality products at affordable prices.

Perfect Fit
WORTH IT! It took my "classic" hunting shotgun and helped to transform it into a CQB tool (hopefully it'll never be needed for that).

Have a question about this?

This will be displayed next to your question.

Can a modified choke be installed and can the breaching muzzle be removed?
Answer: Hi Isaiah! This barrel has a fixed breacher that cannot be taken off. It is not cut for chokes so a modified constriction cannot be added. The barrel is "Cylinder Bore" meaning it has no constriction, and will provide the widest spread with shot, and best accuracy with rifled slugs.
Hello, I have a maverick 88 all purpose with a 28 inch barrel. I was wanting to shoot buckshot and slugs. Would this barrel/choke be a good choice ?
Answer: Hi Brandon! This shorter barrel should fire either of those types of projectiles just fine.
I have a Mossberg Maverick 88. Does this barrel come with instructions in the package on how to install it? Thanks.
Answer: Hi Chris! Please refer to pages 7 and 3 of the owner's manual, respectively: https://resources.mossberg.com/hubfs/manuals/13002-Maverick-88-91.pdf
Will this make my shotgun capable of shooting slugs ?
Answer: Hi Brandon! Any smoothbore barrel should safely fire rifled slugs. This barrel is by all means slug compatible.
My 500 all purpose holds 5+1, is this barrel compatible? Thank you
Answer: Hi Jerry! Thanks for reaching out. The manufacturer says this barrel is for 12 Gauge Mossberg 500 and Maverick 88 6-shot models.
