Description
MDT built The Competitor to take the guesswork out of a match rifle build. Instead of piecing together a chassis, forend, grip, and stock from a parts list, you get MDT's most modular platform already set up for PRS, NRL, and other precision games. Drop in your Remington 700 long action barreled action, torque the action screws, and you are ready to head to the range without any bedding or gunsmithing.
What Sets The Competitor LSS Gen3 Apart
The heart of this kit is the flat, wide competition forend with a full integrated ARCA rail. That means locking into a tripod, clamping a bipod, or riding a barricade happens fast, without adapters or fuss. The forend also carries M-LOK slots along the sides and bottom plus a built-in barricade stop, so you can add weights, bags, and accessories wherever your stage demands. The chassis uses aluminum V-block bedding for a tight, repeatable fit that free-floats the barrel and helps every shot land where you called it.
Dialing In Your Remington 700 LA Build
The kit ships with the SRS-X Lite buttstock and an adjustable length of pull, so you can set the rifle up to your frame and your position behind the scope. It runs standard AICS pattern magazines and takes any AR-15 style pistol grip, giving you room to tune the feel. An ambidextrous magazine release lets you drop mags with your trigger finger and keep your head in the fight.
Modular When You Want to Change Things
Even though it arrives pre-built and competition-focused, the Gen3 platform stays fully modular. The barreled action stays put in the center base, which means you can swap the forend, buttstock, or grip down the road without losing your zero. Finished in Flat Dark Earth Cerakote over CNC-machined 6061 aluminum, it looks as sharp as it shoots and holds up to a long season of matches.

Frequently Asked Questions
Does the Competitor LSS Gen3 kit come ready to shoot out of the box?
It comes fully assembled with the competition forend, SRS-X Lite buttstock, grip, and buttstock interface already installed. All you supply is your Remington 700 long action barreled action, then drop it in and torque the two action screws. No bedding or gunsmithing is needed to get on the range.
What magazines does this chassis use?
The LSS Gen3 runs standard AICS pattern magazines, which are widely available for the popular long action calibers. It also features an ambidextrous magazine release so you can drop mags quickly from either side. This makes reloads fast and keeps you in position during a stage.
Can I change parts on the Competitor LSS Gen3 later without losing zero?
Yes. The barreled action stays mounted in the center base, so you can swap the forend, buttstock, or grip without ever pulling the action. That keeps your zero intact and lets the rifle evolve as your needs change, whether you want a lighter setup or a fully weighted competition rig.
Will this fit any Remington 700 long action rifle?
This kit is cut for the right-hand Remington 700 long action footprint, which covers a wide range of factory and custom actions built on that pattern. Confirm your barreled action matches the Remington 700 LA footprint before ordering. Actions sharing that footprint will drop right in.
