Description
This MDT build takes one of the most respected production bolt actions out there and turns it into a ready-to-run long-range and big game rifle. At its heart is the Howa 1500 barreled action chambered in .300 Win Mag, a flat-shooting magnum cartridge with the energy to reach way out there and stay honest on game. MDT pairs that action with their aluminum chassis and finishes the whole package in a hunter orange MCP camo Cerakote, which gives it serious presence while adding real abrasion and corrosion resistance. An optic comes included, so this is close to a grab-and-go setup once you get it zeroed.
What the MDT 117339DLC Brings to the Field
The Howa 1500 action has a well-earned reputation for accuracy straight out of the box, backed by a cold hammer forged barrel, a forged one-piece bolt with dual locking lugs, and the two-stage HACT trigger. Factory Howa 1500 rifles carry a sub-MOA guarantee, and in .300 Win Mag you get a long-action magnum that handles everything from elk and moose to steel at distance. A three-position safety gives you load, carry, and fire options without fuss.
Chassis Feel and Magazine Setup on the 117339DLC
Dropping the barreled action into an MDT chassis changes the whole personality of the rifle. You get a rigid aluminum platform that free floats the barrel for consistency, an AR-style grip interface, and the kind of ergonomics precision guys look for. MDT chassis systems run AICS-pattern detachable magazines, which are easy to source and reload on the clock. The result is a magnum that feeds cleanly and handles far better than a traditional hunting stock in a .300.
Between the proven barreled action, the chassis upgrade, the magnum chambering, and that included glass, this is a lot of rifle in one box. The orange MCP camo finish is the cherry on top for anyone who wants their rig to look as good as it shoots.

Frequently Asked Questions
Does the MDT 117339DLC come with an optic?
Yes, this package ships with an optic included, so you are not starting from scratch on glass. You will still want to confirm your mount is torqued and get the rifle zeroed before heading afield. Once that is done, it is about as close to a complete setup as a magnum chassis rifle gets.
What caliber is this MDT Howa 1500 chassis rifle chambered in?
It is chambered in .300 Winchester Magnum, a long-action magnum known for flat trajectories and heavy downrange energy. That makes it a strong pick for larger big game like elk and moose, as well as longer-range target work. Expect noticeable recoil that comes with the territory on a magnum thirty.
What magazines does this chassis rifle use?
MDT chassis systems are built around AICS-pattern detachable box magazines, which are widely available and easy to swap. For the .300 Win Mag, you will want long-action magnum magazines sized for the cartridge. Having spares on hand makes range days and hunts a lot smoother.
Is the Howa 1500 action accurate enough for long range?
The Howa 1500 has a solid reputation for out-of-the-box accuracy, helped by its cold hammer forged barrel and two-stage HACT trigger. Factory Howa 1500 rifles are backed by a sub-MOA guarantee. Dropping it into an MDT chassis that free floats the barrel only helps consistency, so this rig is well set up for reaching out.
