Description
The MDT SRS Lite is a fixed skeleton buttstock built for anyone running an MDT chassis who wants real adjustability without the extra weight. The skeletonized body is CNC-machined from 6061-T6 aircraft-grade aluminum, so it stays stiff and true while trimming away the material you don't need. That matters when you're chasing consistency, since a stock that doesn't flex gives you the same feel shot after shot.
Dialing In the SRS Lite
Where this stock earns its keep is the fit. Length of pull is set with stacked 1/4-inch polymer spacers, so you can add or remove them to match your build, layers, and shooting position. The cheek riser adjusts up and down along the rods and locks in with two brass-tipped set screws, giving you near-infinite height positioning to nail a repeatable cheek weld behind glass. Loosen, slide, tighten, and you're done. There's even an integrated bolt cut-out in the cheek rest so you can pull the bolt without fighting the stock.
Sling Options and Chassis Fit
The SRS Lite comes ready for multiple carry setups with ambidextrous QD flush cup sling mounts, so lefties and righties get the same options for sling loop placement. It's designed to work with MDT chassis systems that use a fixed buttstock interface, and it can run on carbine buffer tube setups with the correct MDT adapter. If you're building on an MDT platform and want a clean, comfortable, precision-minded stock, this one slots right in.
Why the SRS Lite Works
Think of this as the sweet spot between a bare-bones fixed stock and a full-featured adjustable rig. You get the strength of solid aluminum, the tuning range that helps in prone and off the bag, and a weight-conscious build that won't throw off your balance. It's a straightforward upgrade that pays off every time you settle in behind the rifle.

Frequently Asked Questions
What rifles and chassis does the MDT SRS Lite fit?
The SRS Lite is designed to work with MDT chassis systems that use a fixed buttstock interface. It can also run on carbine buffer tube setups when paired with the correct MDT carbine-to-fixed adapter. Before ordering, confirm your chassis interface so you get the right fit.
How do you adjust the length of pull and cheek height on the SRS Lite?
Length of pull is set with stacked 1/4-inch polymer spacers behind the buttpad, so you add or remove them to match your build. The cheek riser adjusts up and down along the rods and locks in place with two brass-tipped set screws using a hex key. Both adjustments are simple hand-tool jobs you can dial in at the bench.
Does the MDT SRS Lite come with sling mounts?
Yes, it includes ambidextrous QD flush cup sling mounts, so right- and left-handed users get the same sling loop placement options. That gives you flexibility for how you carry and steady the rifle without buying extra hardware.
Is the SRS Lite lighter than a standard MDT buttstock?
The skeletonized 6061-T6 aluminum body is built to trim excess material while staying rigid, so you get solid strength at a lower weight. It's a good pick when you want adjustability without adding bulk to the back of your rifle.
