The AR 15 ergonomics and versatility of the LSS chassis is exactly what the Mossberg MVP rifle platform needed. It only take a few minutes to install and the action bedding is rock solid. The fit and finish of the chassis is top shelf and it transformed my MVP into a real "Professional" grade tack driver!!

this chassis is by far transformed my favorite rifle into a masterpiece.
the only issues i had was that one of the action screw holes was not drilled correctly in my personal chassis-about 2-3 millimeters off center .
not a issue for me being a gunsmith tho. quality of the machining was top notch. looks are top notch. and its cost to other chassis systems is spot on. please keep up the great work and ill keep suggesting your products to all those who will listen. (Posted on 2/3/2015)

Simple, easy, looks and does what it says it does. Review by DeadMeat

Ease of Installation
Quality
I purchased my MDT LSS from a dealer in Australia.

Fitting my Tikka T3 action was a breeze, the fitment was fast and the machining and anodizing is top notch. No burrs, nicks, or rough bits. I couldn't fault it, but for one little niggle.

After 80 rounds of 7mm-08, and a few months of humid tropical weather, it is still in top condition. I've spilled copper solvent on it, oils, grease and sweat and it doesnt care.

The only, only single one bad point, is the release button for the AICS magazine: It rusts!!

I think that perhaps it and the recoil lug (built in to the stock on Tikka's) are the only parts that may corrode, and even then its only mild surface rust that a quick wipe with some gun oil clears away.
(MDT Comment: The lever process has been changed to a Nitriding process to eliminating rust issues)

To sum up, the product is of High Quality, it Looks Great, and it is priced very fairly.

I'll buy another, and Id recommend you get one. (Posted on 2/3/2015)

LSS is the only stock I've seen for Model 7 that's compatible with AI type magazines.
Combined with a side folder you get an amazingly portable package that's 27" long when utilizing a 16" inch barrel. Its the perfect setup for the subsonic cartridges I shoot.

Excellent upgrade for the Tikka T3 Review by Grodz
Quality
Price
Ease of Installation
I'm very pleased with the LSS chassis, which is an excellent upgrade for the Tikka T3. It is one of the rare chassis available for the Tikka (most are for the Remington 700), and being Canadian-made, avoids the complexity, uncertainty, and cost of trying to import a US-made firearm accessory.

It is precisely machined and easy to install. It works well with .308/7.62x51 Accuracy International 5- and 10-round steel magazines, as well as MDT's new 10-round polymer magazines (a great upgrade from the Tikka's standard 3-round magazine).

The Tikka has a narrow receiver which can cause ejection issues if the magazine is not positioned precisely at the right height. I have had no ejection problems with the LSS chassis.

There is only space for a 6.5" bottom rail (no side rails), but that has not been a problem for me. I've installed the following accessories on the rail:

1. T-FL folding foregrip (FAB Defense): installed nearest to the magwell. This provides a very good grip for various unsupported firing positions (standing, kneeling, sitting, prone), and allows comfortable carry when stalking/patrolling.

2. Offset sling mount: installed in front of the foregrip. It allows a quick-release sling-stud mount to be installed on the left side, making for comfortable carry with a 2-point sling.

With the above 2 items, there remains 2.75" of rail space in the front for attaching other accessories (ex. bipod, flashlight, or laser).

3. T-Pod G2 bipod/foregrip (FAB Defense): installed in front of the sling mount. Can be used as a vertical foregrip, or as a short bipod (6-8" height). A bit heavy (12.5oz), and redundant as a foregrip, but easy to install, and remove if not needed. Other picatinny-mounted bipods could be used as well.

For the shoulder stock, I use a CBS collapsible stock and an ACP cheek riser, both made by CAA. This provides an 11.25 to 15.5” LOP (I use mine on the 2nd position, for a 13.5” LOP), as well as a perfect cheekweld for my 32mm scope (it has 0-1” of height adjustment).

With the scope removed and the cheek riser lowered, I can also use the Tikka's fibre-optic sights as backup (I have the Battue model).

I use a Mod 0 Gunfighter pistol grip (BCM), which provides a more natural grip for me, for various shooting positions and for stalking/patrolling.

This improves the already excellent and accurate Tikka T3 by enabling excellent ergonomics, as well as the use of 10-round magazines. A very worthwhile upgrade overall. (Posted on 2/3/2015)
Fantasic Review by BadTaiming
Ease of Installation

I ordered a left hand short action for my Tikka T3 in .223 .
The chassis was easy to install and looks fantastic.
The stock has a natural grip for shooting from standing and is very solid from shooting from prone or off a bench.
I have only 3 minor concerns .
1 no flat dark earth stocks in left hand.
2 the MDT ploy mag should have room for 11 loading 10 is going to be hard on the spring.
3 last bullet in mag tips up every once in a while. (speed shooters beware).
I will buy a second LSS for my 300W mag Tikka when they become available. Hopefully the mags can hold a 230gr Berger bullet because my Tikka mags can't. (Posted on 2/3/2015)
Awesome upgrade for Tikka T3 - Ruger American next? Review by R.J.
Price
Ease of Installation
Quality
Awesome, affordable stock upgrade for Tikka T3. Especially in keeping with a totable rifle like the T3 Lite.

It would be outstanding if MDT could produce this chassis for the Ruger American Rifle, a great value-priced rifle that competes with the Savage Axis.

However, the Axis suffers somewhat from using the same receiver for short & long actions, whereas the RAR has separate SA & LA receivers, as one would expect. The RAR Compact, with a light 18" barrel, is crying out for a platform like the LSS to realise its huge potential.

MDT would have to engineer a space-efficient solution that deals with the RAR's tang safety, which in some respects is a nice feature but looks like it might interfere with where you might locate the buttstock adapter.

Anyway, great job, guys! (Posted on 2/3/2015)

Amazing minimalist modular product except maybe for back inch Review by G.M.
Price
Ease of Installation
Quality
A true minimalist chassis at a low price. Only issue is with the lack of modularity of the stock adapter.

Many lightweight users will desire a folding stock, but the AR stock adapter wastes an inch & makes implementing this difficult. Though AR stocks are readily available, a bolt action rifle does not have a recoil tube & this is a wasteful element of an otherwise elegant design.

Something like the Ace AR-15 Compact Receiver Block might suffice to permit the attachment of a folding mechanism.

It would be well worth considering a future edition in which the AR tube adapter is replaced with a shorter adapter that can accommodate fixed OR folding stocks. AK or ACE receiver blocks come to mind.

Great work, guys! Very exciting product. (Posted on 2/3/2015)
Simple and elegant design, buy the adaptor for fixed stock too. Review by TDK
Price
Ease of Installation
Quality
The stock takes no time to install and it extremely light weight. It is an ideal option for a light weight tactical rig. It's nice that it uses AI mags too, even though they are more expensive, they always work!

I like the small fore-end, just wish they had the bolt on top piece available now (there are 4 screw holes and 2 locator pin holes in the top surface of the fore-end that allow you to install a top on the fore-end). It will give you something to grab onto when the barrel is hot.

It would be great to install a Magpul PRS sniper stock, but you have to buy the fixed stock adapter to do so. This adds about 3/4 of an inch. Given that this is a no frills stock and is very inexpensive for the quality you get, it is not that big of a deal. It works fine with a carbine stock as long as you have a raised cheek piece adapter.

Overall a nice piece of work! (Posted on 2/3/2015)
Great light weight chassis at a great price Review by Rich
Ease of Installation
Quality
Price
I had been looking to upgrade my SA .308 Remington 700 stock and add a detachable mag when I came across the MDT LSS. I liked the light weight, simple, modular design & price!

I ordered the LSS w/ the fixed stock adapter as I had a Magpul PRS stock. This was the only thing I did not like about my set up. The LOP with the castle nut, adapter and PRS stock was too long for me to be completely happy with. I had to move my scope as far back as my set up would allow to get an acceptable eye relief. Since the issue was with my stock set up I knew there had to be a better option for the LSS.

I FOUND IT!!! I replaced the PRS with a XLR Tactical Stock which mounts directly to the LSS without the need for the castle nut or fixed stock adapter. With this stock I was able to move the scope and achieve the LOP & eye relieve I had with my original remy stock. If you want the fixed stock without the adapter due to the added length of pull, these stocks work perfectly with the LSS and I have been extremely happy with the LSS since making this change.

The LSS chassis was the perfect upgrade for my rifle. I have a strong, ridged base w/ an adjustable set up, no feed issues with the AM mags & tighter groups at 100, 200 & 500 yards...all for a great price. (Posted on 2/3/2015)

I recently purchased the MDT LSS chassis for the Remington 700 and I'm very happy with the product. The quality of the machining is excellent and the Rem 700 system fitted nicely with no modifications needed. The slot for the recoil lug is a bit thicker than the lug on the Rem system, but keeping the system pressed backwards when mounting this caused no problem. The precision of the finished system (700 LTR .308win) turned out to be excellent. Sub MOA groups get delivered over and over it the shooter does his job well. The only negative experience I had so far is that the sling stud broke of after just a few shots with a bipod. The sling stud could have been more robust and when replaced by another stud with a proper full thickness nut the problem was solved. But to summarize it's a fantastic product to a bargain price!
