MDT LSS Remington 700 Chassis First Look

MDT LSSModular Driven Technologies recently sent us one of their new LSS Chassis Systems. The LSS is a very minimalist chassis that offers you the option to use your favorite AR15 pistol grip and adjustable buttstock. One of the most important features is that the LSS allows your Remington 700 short action rifle to accept Accuracy International AICS pattern magazines. Our initial impression is that the LSS is a very solid piece. Our factory Remington 700 Varmint rifle dropped right in.

The slim, short forend free-floats your barrel and allows for a solid point to mount a bipod or sling. The LSS comes out of the box with a sling stud installed. We chose to install the optional 2.5″ picatinny rail to facilitate mounting our Alamo Four Star DLOC equipped Harris bipod.

The LSS does not include a pistol grip or buttstock. You must provide those yourself. We chose to install a Falcon Ergo Tactical Deluxe grip and Magpul CTR stock. The comb height with the CTR stock is too short for a good cheek weld with a typical low-mounted rifle scope. Adding a Magpul 0.75″ Riser resolved this perfectly.

Overall the quality is very good. The chassis is advertised as Type-3 Hard Anodized with a black coating. We did chip some of the black coating off of the pistol grip lug when we installed a hard plastic grip. Otherwise the installation was uneventful.

The LSS is available for the Remington 700 Short Action, Savage and Tikka T3.

The LSS retails for $399 from Brownells and is available in black or FDE. This price point places the LSS in a position to take the “best buy” title for entry level chassis systems. At 1.6 lbs (without butt and grip) it is one of the lightest Remington 700 Chassis we have encountered.

Once we get some range time with the system we will report back with a full review.

  1. The receiver extension/buffer tube assembly does not come with, correct? I am very excited to see a good, reasonably priced chassis system available for the Savage rifles. However, as I have a McMillian A3 on mine, currently, I don’t know if this chassis is “enough” to make me switch. The biggest reason to switch would be to be able to use AICS mags.

  2. What about a folding system like the Law Tactical AR Folding Stock Adapter?
    They way you have it setup with the CTR and riser, addition of folding ability would make a handy little tac rifle.

  3. Great review! I have been looking for more info on these. The handguard area appears to be a bit compact with the bipod. Have you tried to run a barricade stage with this stock? I am curious as to whether there is enough room to rest the rifle on the barricade without interference from the bipod?

    1. Ran a barricade drill the other day without problem. Of course not all barricades are created equal. If it is extremely thick, you may have an issue, but if that is the case there are other ways to game it.

  4. Great review. How does the LSS Chassis compare to other stocks such as a Bell & Carlson in grouping? In your opinion what stock would you recommend to offer the best for accuracy if you were building a rifle that will mainly be used for deer hunting, but also began in long range shooting?

    1. Accuracy between the B&C Light Tactical and the MDT LSS is very similar. The LSS has the advantage of a built in magazine system. That would be a great benefit in competition shooting.

  5. I plan on picking up a rem 700 5r 24″ 308 but my question is how much more accuracy will this chassis system provide over the stock HS precision stock with the aluminum pillars? I know u have a lot of experience with bolt on chassis systems, what is your favorite right now for the rem 700 action? Keep up the great reviews and cant wait to watch your full review on this. P.S. TAC 21 looks interesting also I hope they send you a demo to review.

  6. Everyone said it but again another great review! Need some advice as I have never purchased a chassis before. I have a Remington 700 .300 WSM. Would you steer me in the right direction as to all of the accessories I will need to make this range ready? Using it for hunting as well.

    Thanks!

  7. I am looking to upgrade to a chassis and came across a few of your reviews, great reviews indeed. I have a Remington 700 .300 WSM and have decided to go with the MDT LSS. Would you recommend all of the accessories needed?

    1. Not a whole lot of accessories needed. You will just need to choose an AR buttstock and pistol grip. I suggest the Magpul MOE or CTR and the .75″ Riser. If you want to use a rail attach bipod, you will need a picatinny rail section from MDT or a Magpul MOE rail section.

  8. nice quick simple video thanks for taking the time to do that. question what length of barrel is in the video and what length do you reasonable believe would work I have a 28″ and if I balance out the butt section would it still work. I like the chassis system a lot however the 9″ forend seems too small.

  10. fitment issues with savage 10s. Have to use a stock with a close cheek weld to use magnification (scope). PRS will not do

  11. Would a single point sling be appropriate for a bolt gun with this setup? You’d probably need a shorter barrel for it… I’ve got a 20″ .308 r-700 I want to put on one of these.

  12. Does this chassis system work with the remington 700 sps varmint with the 26″ barrel in .308 or does it have to be the 700 short action?

  13. I’m wondering if you have any experience with the MDT TAC 21 chassis and if so what it was? I’m looking into doing a build but I read some reviews where people were complaining about their groupings not being as tight.
