Description
Buying a rifle and a scope separately, then sorting out rings and mounting, adds time and money before you ever squeeze a trigger. Mossberg took care of all that with this Patriot combo. Model 28123 pairs their proven bolt action in .300 Winchester Magnum with a Vortex Crossfire II 3-9×40 riflescope mounted on Weaver-style bases, so your main job after pickup is a box of ammo and a trip to the range to dial in your zero.
What the Patriot .300 Win Mag Brings to the Field
The 24 inch button-rifled barrel is fluted to shave weight, free-floated for consistency, and finished with a recessed crown. It is also threaded, so adding a muzzle brake or suppressor down the road is simple. A 1:10 twist rate stabilizes the heavier bullets that make the .300 Win Mag such a capable elk and mule deer cartridge, and the full-length tube helps the magnum case burn its powder for the velocity you paid for. The spiral-fluted bolt runs smooth with a streamlined handle and knurled knob that is easy to work with gloves on, and the 3+1 drop box magazine makes loading and unloading quick and painless.
A Trigger and Stock Built for Real Hunts
Mossberg's LBA trigger is the sleeper feature here. It is user-adjustable roughly from 2 to 7 pounds, so you can set a clean, crisp pull that suits how you hunt without a trip to the gunsmith. The black synthetic stock shrugs off rain and rough treatment, with textured grip panels on the forend and wrist plus a straight comb and raised cheekpiece that line your eye up naturally behind the scope. A recoil pad on the back end takes some sting out of the magnum push.
The Vortex Crossfire II Side of the Deal
The Crossfire II 3-9×40 wears the Dead-Hold BDC reticle, which gives you hashmarks for holdover at longer distances instead of pure guesswork. Fully multi-coated lenses keep the picture bright at first and last light, the fast-focus eyepiece gets you a sharp reticle quickly, and the nitrogen-purged aluminum tube is sealed against fog and water. Generous eye relief matters on a .300 Win Mag, and this scope has it. Solid rifle, solid glass, one box.

Frequently Asked Questions
Is the scope on the Mossberg Patriot Vortex combo already mounted and sighted in?
The Vortex Crossfire II 3-9×40 comes mounted from the factory on Weaver-style bases, so you will not need to buy rings or a mount. Plan on a range session to zero it though. Factory-mounted scopes are boresighted at best, and every rifle and ammo combination shoots a little differently.
Can I put a muzzle brake or suppressor on this Patriot 300 Win Mag?
Yes, the 24 inch barrel on this model comes threaded from the factory, so it accepts a brake or suppressor without any gunsmith work. A brake is a popular add on this rifle since the .300 Win Mag has some real thump, and taming that recoil makes range sessions a lot more pleasant.
How does the LBA trigger adjustment work on the Mossberg Patriot?
The Lightning Bolt Action trigger is user-adjustable across roughly a 2 to 7 pound range using a simple screw adjustment once the barreled action is out of the stock. It also uses a blade-style safety in the trigger face for a clean, crisp break. Most hunters set it somewhere in the 2.5 to 3.5 pound range for field use.
Is the Crossfire II 3-9×40 enough scope for a .300 Win Mag?
For most big game hunting, yes. The 3-9×40 range covers everything from close timber shots to reasonable cross-canyon distances, and the Dead-Hold BDC reticle gives you holdover references for stretching it out. The scope also offers generous eye relief, which you will appreciate behind a magnum cartridge like this one.
