The UBS-12 (Under Barrel Shotgun 12 Gauge) is a door breaching shotgun system manufactured by Lockhart Tactical.
Typically Soldiers or Law Enforcement officers are forced to carry a breaching shotgun in addition to their standard issue rifle during operations. Our UBS removes this requirement. Our system consists of a Grizzly shotgun embedded in our proprietary quick release mount which is to be used in an underbarrel configuration much like the M203 grenade launcher.
Our shotgun cannot be operated independently due to not having a pistol grip behind the trigger. When firing the UBS, the magazine of the parent firearm must be used as a pistol grip. We will soon be releasing a proprietary Pistol grip and Buttstock which will be able to be quickly attached and detached on the UBS for independent firing without being attached to another firearm.
What can the UBS-12 Mount do for me?
Whether or not you're a Solider, LE Officer or Professional using this device for breaching, our UBS has a lot to offer. Civilian Hunters can benefit immensely by carrying our tiny UBS under their favorite bolt action hunting rifle. Nothing is better than peace of mind and security of having 12GA Slugs or Buckshot at your finger tips when it's needed most.
Apart for security reasons, Hunters could also quickly attach our UBS to help ensure they don't go home from a hunt empty handed. Maybe you won't see a deer cross your path, but if an unlucky flock of turkeys happens to surprise you... Seize the day! Our shotgun features a 2+1 magazine which means its perfectly legal for hunting.
Use our Mount to attach your currently supported shotgun, and connect it to another firearm platform!
The Lockhart Tactical UBS-12 features dual locking levers manufactured 100% in the USA by American Defense. These patented quick release, automatic locking levers are the best in the world. Rest assured, these won't ever be coming off unintentionally!
Our proprietary billet aluminum mounts are machined entirely in BC, Canada and requires a mere 10 picatinny rail slots (4" / 10cm") to attach securely. The UBS-12 mount features a proprietary provision to accept our quick attach Buttstock and Pistol grip combination to convert into a shoulder fire-able compact shotgun which still retains the ability to be under barrel mounted. The Quick Attach Optic mount will sit on top of the UBS while in the shoulder fired configuration and shall retain zero on optics when detached and reattached.
Our mounts will be compatible with the following firearms:
- Robinson Arms XCR
- Norinco Type 97
- Just Right Carbines (9mm, .40, .45)
- Ruger 10/22
- Mossberg Tactical 715T
- Heckler & Koch HK416

Weight: 0.7 lbs
Your shotgun receiver may need to be drilled and tapped.
We will include 3x custom screws to fit a Dominion Arms Grizzly Shotgun.
They are 6-48 hex screws.
Your factory bolt which secures the buttstock on the rear of the shotgun may work, or some modification may be needed depending on what you are attaching our mount to.
If you are drilling / tapping your own receiver, you may need to use your own bolts.
The UBS should ONLY be mounted on Firearms which have strong ALUMINUM or STEEL picatinny rails embedded into them. Lockhart Tactical will not be responsbile for ANY damage OR injury which may occur involving the UBS-12. Cheap plastic / polymer rails may break and cause damage to the firearms or user. Lockhart Tactical recommends all users seek professional advise from licensed gunsmiths when installing the UBS-12.
