Description
The 300 PRC was built to sling heavy, high-BC bullets way out there, and the Havak Element M3 gives that cartridge a home worth carrying up a mountain. Seekins builds this rifle around their hybrid action, a clever mix of aluminum and steel that shaves real weight without giving up the rigidity you need for consistent accuracy. The 22 inch barrel is 416R stainless wrapped in carbon fiber, threaded 5/8×24 and topped with Seekins' Hunter muzzle brake to take some of the sting out of a magnum cartridge in a light rifle.
What Makes the Element M3 Different
The headline feature here is the patent-pending Quick-Change Barrel Collar, which opens the door to swapping barrels down the road, and Seekins even publishes open-source headspace and tenon specs. The three-lug bolt runs a fast 60-degree throw, so your hand clears the scope and follow-up shots come quick. It pulls out of the action without tools for easy cleaning, and dual ejectors with a sliding extractor keep things running with modern high-pressure loads. The action also accepts extra-long cartridge overall lengths, up to 3.9 inches in 300 PRC, which handloaders will appreciate when seating those long, sleek bullets.
A Stock That Earns Its Keep
The PH3 carbon composite stock sits on a Seekins Mini Chassis and brings an adjustable cheek riser so you can get proper eye alignment behind any scope. A full-length M-LOK rail under the forend handles bipods, ARCA adapters, and sling mounts, while the integrated 20 MOA Picatinny rail with a built-in bubble level gets you extra elevation for stretching the 300 PRC to its potential. The TriggerTech trigger adjusts from 2.5 to 5 pounds, so you can set it crisp and light for the bench or a bit heavier for cold-weather hunts with gloves.
Havak Element M3 in the Field
This is a rifle built by hunters for the backcountry, with a 3+1 capacity fed from an included carbon fiber magazine and backed by Seekins' no-questions-asked lifetime warranty. If your hunts involve long glassing sessions and longer shots, this one deserves a hard look.

Frequently Asked Questions
How is the Element M3 different from the original Havak Element?
The biggest changes are the move from a 90-degree to a 60-degree bolt throw with a three-lug bolt head, plus the new Quick-Change Barrel Collar system. The M3 also gets a carbon fiber wrapped barrel and the PH3 stock with an adjustable cheek riser. The action was designed with modern high-pressure cartridges in mind, with dual ejectors and a sliding extractor for reliable extraction.
Can I swap barrels on the Seekins Element M3 myself?
That's the idea behind the Quick-Change Barrel Collar. Seekins publishes open-source headspace and tenon specifications, so prefit barrels can be installed without sending the rifle off to a gunsmith. As with any barrel swap, verifying headspace with gauges is the smart move before heading to the range.
Is a 22 inch barrel long enough for 300 PRC?
You'll give up some velocity compared to a 24 or 26 inch tube, but the 300 PRC still delivers strong long-range performance from 22 inches, and the shorter carbon-wrapped barrel makes the rifle far more packable for mountain hunts. The 1:10 twist stabilizes the heavy, high-BC bullets the cartridge was designed around. For most hunting distances, you won't feel shortchanged.
Does the Havak Element M3 come with a muzzle brake and can I run a suppressor?
Yes, it ships with Seekins' Hunter muzzle brake installed on a 5/8×24 threaded muzzle. That's the most common thread pattern for .30 caliber suppressors and aftermarket brakes, so swapping to a can is straightforward. A suppressor pairs nicely with this rifle since the brake on a light magnum can be loud at the bench.
