MDT LSS GEN3 | THE COMPETITOR | SAVAGE AXIS SA
Turn Your Savage Axis Into a Competition-Ready Rifle.
The MDT LSS Gen3 The Competitor Chassis 115013-BLK gives a Savage Axis short-action rifle the foundation, support surfaces and adjustability normally associated with a dedicated match build. Its 14.32-inch Competition Forend, integrated 10-inch ARCA rail, and SRS-X Lite buttstock are already brought together as a complete Black chassis kit.
A Savage Axis does not have to remain a basic sporting rifle. If you enjoy stretching its legs on steel, shooting from barricades or building a rifle around positional competition, the stock is one of the biggest differences you can feel. A wide, flat forend settles onto a bag differently than a narrow factory stock. A long ARCA interface gives you room to move a bipod or tripod clamp until the rifle sits where you want it. And an adjustable rear setup helps keep your shooting position familiar from one stage to the next.
That is the appeal of The Competitor. Rather than collecting the chassis body, long forend, buttstock and grip one piece at a time, you start with MDT's competition-oriented LSS Gen3 configuration. The core is CNC-machined aluminum with V-block action support; the outer components can still evolve as your match setup does.
A Competition Forend That Earns Its Space
The 14.32-inch Competition Forend gives the rifle a broad support surface for bags, barricades and improvised positions. Its integrated 10-inch ARCA dovetail lets you position a compatible bipod or tripod clamp along the underside without buying a separate full-length ARCA rail. M-LOK slots across the sides and bottom offer room for weights and other control accessories. There is also an integrated barricade stop when you want a repeatable front contact point.
Start with the Right Fit at the Rear
MDT pairs this chassis with the SRS-X Lite buttstock and Elite Vertical Grip. The stock provides a purpose-built rear support and length-of-pull adjustment by spacers, while the grip keeps the trigger-hand position comfortable when shooting from bags or behind a tripod. The LSS Gen3 architecture also allows compatible forend and rear components to be changed without removing the barreled action from the center chassis section.
Savage Axis Short Action, Not Savage 110
This SKU is cut for the right-hand Savage Axis short-action inlet, including compatible Axis and Axis II variants. It is different from MDT's standard Savage short-action chassis for the 10/110-series action. The system uses short-action AICS-pattern magazines; choose the magazine by the rifle's cartridge, since a .223 magazine and a .308 / 6.5 Creedmoor magazine are different products. This is a centerfire Axis chassis, not a Savage Mark II rimfire stock.
Pair It With
Once the chassis is in place, it is worth spending on the little details that matter to your position. The adjustable MDT thumb rest gives your support hand a repeatable point of contact. Our PPFWR forend weights let you add mass where it helps the rifle settle on a bag or barricade, while MDT Baker Wings add a wider support surface for positional shooting.

The best-balanced rifle is the one that settles naturally in your positions. The Competitor has the forend length and mounting space to make deliberate adjustments. Our Pete’s Pillars PPFWR M-LOK forend weights give you a practical way to add weight toward the front without changing the chassis itself. Start with the feel you prefer behind the rifle, then place weight to support it.

ARCA Bipods for a Match-Ready Forend
The Competitor already has an ARCA rail. Pair it with an ARCA-mounted bipod that matches how you shoot, from the practical GRND-POD to Ckye-Pod options built for demanding positional work.

If the rifle will spend more time at matches, consider the Ckye-Pod Gen3 Compact or Double Pull for different support-height needs. The MDT Mountain has a different appeal if minimizing bipod weight matters more than maximum adjustability.
Match the Magazine to Your Cartridge
AICS magazines give the Savage Axis chassis a different loading arrangement from the factory stock. Select the magazine for your cartridge: .223 Remington requires its own magazine geometry, while our .308 / 6.5 Creedmoor metal magazine is an option for matching chamberings. A magazine chosen for one cartridge is not automatically appropriate for another.

Magazines, Glass and Scope Mounting
The AICS conversion opens up magazine choices, while good optics and properly selected rings help make the most of a rifle built for shooting at distance. Match your magazine to the exact chambering and your rings to the optic tube.

If most of your time is spent hunting, carrying the rifle or shooting from a traditional bench, the LSS Gen3 The Worker for Savage Axis SA has a shorter forend and a different rear configuration. The Worker is an alternative kit for a different use, not an accessory you need to add to The Competitor.

Weight & Balance
Pete’s Pillars Forend WeightsFrequently Asked Questions
Does 115013-BLK fit the Savage Axis or the standard Savage 110 action?
This SKU is the right-hand Savage Axis short-action inlet. The standard Savage short-action 110-series chassis is a separate inlet and should not be treated as interchangeable.
Will it fit the Savage Axis II?
MDT lists numerous Savage Axis and Axis II short-action models under this inlet. Confirm your particular action and magazine configuration before selecting 115013-BLK.
Is The Competitor a complete chassis kit or just a bare LSS Gen3 base?
It is a complete Competitor chassis configuration, not the bare center section. The listed package includes the chassis body, Competition Forend, XTN buttstock interface, SRS-X Lite buttstock, Elite Vertical Grip and trigger guard.
What is the advantage of the Competition Forend?
The 14.32-inch forend gives more usable support length for bags and barricades and provides M-LOK mounting alongside a built-in ARCA rail for supported positional shooting.
Do I need to buy a separate ARCA rail?
No. The Competition Forend already includes a 10-inch integrated ARCA rail. Select an ARCA-compatible bipod or tripod clamp if you want to use that mounting interface.
What magazines does this Savage Axis chassis use?
The Savage Axis short-action LSS Gen3 uses AICS-pattern short-action magazines. Match the magazine to the chambering; .223 Remington and .308 / 6.5 Creedmoor use different feed geometry. For compatible .308 and 6.5 Creedmoor builds, see our MDT metal magazine.
What buttstock and grip are included?
MDT specifies the SRS-X Lite buttstock and Elite Vertical Grip, together with the XTN interface, in The Competitor package.
Can I use my current heavy barrel?
MDT lists up to a 1.25-inch straight-diameter barrel for the Competitor chassis. Barrel contour, mounting equipment and other clearance requirements still depend on the specific build.
Can I add weight and other match accessories?
Yes. The Competition Forend has M-LOK slots for compatible accessories. Our Pete’s Pillars PPFWR forend weights can help tune forward balance, while the MDT adjustable thumb rest provides an additional support-hand contact point.
How is The Competitor different from The Worker?
The Competitor is the dedicated long-forend, ARCA-equipped configuration with the SRS-X Lite buttstock. The LSS Gen3 The Worker uses a more compact forend and a different buttstock setup for a general-use rifle.
