MDT Fuzion, Fuzion Ti, and Razor Actions: $1,199 to $1,749

MDT is selling bolt actions. On August 7, 2026 the chassis maker put three Remington 700 footprint actions on sale through its dealers and mdttac.com: the stainless Fuzion at $1,449.99, the titanium Fuzion Ti at $1,749.99, and the Razor at $1,199.99. A long action Fuzion in 338 Magnum lists at $1,549.99.

All three share the same core: a Remington 700 footprint, a one-piece fluted 4340 chrome moly bolt with a nitride finish, a mini M-16 style extractor, an integrated recoil lug, a 1.350 inch receiver diameter, and a 1 1/16 x 16 tpi barrel tenon. The standard bolt throw is 75 degrees across the line, with a 90 degree throw on the long action 338 Magnum Fuzion where the cartridge diameter forces it.

This is a real expansion rather than a badge exercise. MDT has spent a decade selling everything that surrounds an action, chassis, magazines, bipods, and the grips and buttstocks covered in our breakdown of MDT's rifle control points. The action was the one part of a precision rifle it did not make.

The Fuzion, Fuzion Ti, and Razor are not new designs. They are Lone Peak Arms actions, and MDT acquired Lone Peak earlier in 2026. The Utah shop had been building custom actions since 2014, and the specifications carry over unchanged: the same 416R receiver on the Fuzion, the same 6Al-4V titanium on the Fuzion Ti, the same 75 degree throw, the same barrel tenon. So do the prices. Lone Peak listed the Fuzion at $1,449.99, the Fuzion Ti at $1,749.99, and the Razor at $1,199.99, and MDT relaunched all three at exactly those numbers.

For a buyer this is the most useful fact in the announcement, and it cuts in MDT's favor. A chassis company shipping its first in-house action would be an unknown: new machining, new tolerance stack, no field history, and no way to know how the bolt feels after two thousand rounds. Instead these are actions with a decade of use behind them, now attached to a larger company's distribution and warranty. MDT's CEO framed it the same way, saying he has "personally been building on Lone Peak actions for years."

The practical consequence: reviews, forum threads, and gunsmith experience filed under "Lone Peak Fuzion" describe the action you are buying today. That is a deeper body of evidence than a launch-week product usually has.

The Razor and the Fuzion differ on the rail, and the Fuzion Ti differs from the Fuzion on material and nothing else. That makes the decision unusually clean.

Buy the Razor if you have opinions about optic mounting. Its pinned-and-screwed interface takes a full rail, a two-piece rail, or direct-mount rings, so you set your own mounting height and can run rings low over the bore rather than accepting the height an integral rail dictates. It is also the lightest steel option and the cheapest action in the lineup.

Buy the Fuzion if you would rather the mount be settled. The 20 MOA rail is machined from the same block as the receiver, so there is no fastener joint between your scope and the action and nothing to re-torque. That is worth the $250 over the Razor on a rifle that will see recoil and travel, and it is the conventional choice for a chassis build.

Buy the Fuzion Ti only if the rifle gets carried. Titanium takes the short action from 31.5 oz to 19.5 oz, about 12 ounces, for $300. On a mountain rifle that is cheap weight to lose, and the DLC coating on the receiver is there because bare titanium galls. On a bench or barricade rifle the saving is beside the point: those builds are heavy deliberately, and our PRS rifle build guide covers why competitors add weight rather than remove it.

The Remington 700 footprint is the reason to buy any of these rather than a factory rifle. It is the most widely supported action pattern in bolt-action shooting, so a Fuzion drops straight into a chassis, a stock, or a scope base cut for a Remington 700, and it takes any Remington 700 pattern trigger. You are not buying an action so much as buying into an aftermarket.

MDT selling the actions closes an obvious loop: the company already makes the chassis they go into. The ACC Elite is the competition end of that line, and the same footprint fits MasterPiece Arms, KRG, and Grayboe hardware if you would rather not buy the whole rifle from one company. You can filter the chassis, triggers, and barrels that share the footprint in our component catalog.

Barrels are the exception to the drop-in rule. All three actions thread 1 1/16 x 16 tpi, and a prefit barrel has to be ordered for the specific action and cartridge, or cut and chambered by a gunsmith to your action. That is the one part of the build where "Remington 700 footprint" does not mean interchangeable.

An action is roughly a third of a precision rifle, so treat these prices as a starting figure rather than a total. Past the action you need a barrel, a trigger, a chassis or stock, magazines, rings or a base if the action has no integral rail, and glass. A Razor at $1,199.99 paired with an ACC Elite chassis at $1,599.99 is already past $2,700 before a barrel, a trigger, or an optic.

That math is the honest case against a custom action for most shooters. A factory precision rifle delivers a shootable rig for a fraction of it, and our guide to the best precision rifles under $2,000 covers what that money buys complete. The case for a custom action is a specific combination the factory does not sell: a cartridge nobody chambers, a left-hand long action, a titanium receiver on a mountain rifle, or a switch-barrel setup. If you are still choosing the cartridge, our 6.5 Creedmoor rifle guide and long range scope guide cover the two decisions that matter more than the receiver.
