Description
The MDT LSS Gen3 Worker Chassis Kit takes your right-hand Tikka T3x short action and turns it into a slim, hardworking platform without any gunsmithing. Drop your barreled action into the V-block bedding, torque it down, and you have a rig that feeds from standard AICS pattern magazines and mounts a bipod, sling, or light wherever you need one. The whole thing runs on 6061 aluminum with a Cerakote finish, so it holds up to real use in the truck, on the ranch, or out chasing hogs.
What Makes the Worker Kit Tick
This version ships with a short forend wrapped in polymer side panels, which keeps the rifle narrow and comfortable while giving you a bit of grip and some insulation from a hot barrel or a cold morning. Up top you get an enclosed section for mounting optics, an integrated barricade stop at the front of the magwell, and an ambidextrous mag latch that lets you drop empties with a push of your trigger finger. The kit comes together around the CCS buttstock and an Elite AR-style pistol grip, so the ergonomics feel familiar right out of the box.
Built to Grow With Your Tikka T3x Build
One of the best things about the LSS Gen3 platform is that you are never locked into a single setup. Because your barreled action stays put in the center base, you can swap the grip, run a different stock, or bolt on a full-length ARCA forend later without losing your zero. That makes the Worker Kit a smart starting point whether it is a first precision build or another action in a growing collection.
Who This Chassis Suits
Think truck gun, ranch rifle, coyote setup, or a lightweight pack build. The Worker Kit keeps weight down and deployment quick, and it gives newer and seasoned shooters the same core features the serious crowd relies on. It is simple, rugged, and made to get used rather than babied.

Frequently Asked Questions
Does the MDT LSS Gen3 Worker chassis require gunsmithing to install?
No. This is a drop-in setup, so you pull your Tikka T3x barreled action, seat it in the V-block bedding, and torque down the action screws. Most folks have it running in a few minutes with basic tools.
What magazines does the Worker Kit use?
It feeds from standard AICS pattern magazines, which are widely available in short action lengths. If your Tikka currently uses a factory hinged or blind magazine, this chassis converts it over to detachable AICS mags. Note that magazines are not included with the kit.
Can I upgrade the chassis later without buying a whole new one?
Yes, and that is one of the platform's strengths. Since your barreled action stays mounted in the center base, you can swap the grip, buttstock, or forend down the road without losing your zero. That means you can go from this compact Worker setup to a full-length ARCA competition forend by changing just the parts you need.
Will this fit a left-handed Tikka T3x?
No. This particular kit is cut for right-hand short actions. MDT offers a separate left-handed version of the Worker Kit if that is what your rifle needs.
