Description
The MDT LSS Gen3 Competitor takes the guesswork out of building a match rifle. Instead of piecing together a forend here and a buttstock there, MDT already picked the parts that matter for PRS and NRL and bolted them to the same rock-solid Gen3 core. It fits right-hand Tikka T3 and T3x short actions, wears a Flat Dark Earth finish, and drops your barreled action straight in with no bedding or gunsmithing required. Two action screws, about 65 inch-pounds, a quick function check, and you are pretty much ready for the range.
What Sets the Competitor Kit Apart
The headline piece is the wide, flat Competition forend with a 10-inch integrated ARCA rail. That flat bottom parks nicely on barricades and bags, and the ARCA lets you slide a bipod or lock into a tripod without fussing with adapters. It is drilled and tapped for MDT Control and NV bridges, and there are M-LOK slots and pockets along the sides and bottom for whatever else you want to hang on it. Out back you get the SRS-X Lite buttstock with adjustable length of pull and an integrated barricade stop, plus the Elite vertical grip up front.
Built on the Proven LSS Gen3 Core
Every Gen3 chassis is built around a central core that mates to the action, so you can swap forends, stocks, and grips down the road without ever pulling the barreled action or losing your zero. It runs standard AICS pattern magazines, uses an ambidextrous mag latch that drops mags with a push of the trigger finger, and seats the action on MDT's aluminum V-block bedding for consistent, repeatable accuracy. The barrel free-floats the way a precision setup should.
Room to Grow With Your Shooting
The Competitor arrives competition-ready but stays fully modular. Add weights, bridges, or a different grip as your build evolves, or reconfigure it entirely if your goals change. It is a serious foundation that will keep up as you do.

Frequently Asked Questions
What rifles does the MDT LSS Gen3 Competitor fit?
This kit is inletted for right-hand Tikka T3 and T3x short action rifles. The barreled action drops into the chassis core and torques down with the two included action screws, no bedding or gunsmithing needed. If you run a left-hand action or a long action, you would want a different inlet from MDT's lineup.
Does the Competitor kit come with a magazine?
No, magazines are not included with the kit. The LSS Gen3 runs standard AICS pattern magazines, so you have plenty of options from MDT and other makers in the caliber you need. It also uses an ambidextrous mag latch that drops the mag with a push from your trigger finger.
Can I change parts later without losing my zero?
Yes, that is the whole idea behind the Gen3 design. Your barreled action stays mounted to the central core, so you can swap the forend, buttstock, or grip whenever you like without disturbing zero. The Competitor shows up match-ready but stays fully modular for future upgrades.
What makes the Competitor forend good for PRS and NRL matches?
It is a wide, flat forend with a 10-inch integrated ARCA rail, which is exactly what you want for stable barricade and tripod work. You can clamp a bipod or lock into a tripod without extra adapters, and the M-LOK slots and pockets give you room for weights, barricade aids, and other accessories.
