Tikka T3 Stock Options: MDT Light Sniper System Chassis

Posted on February 9, 2014

One of the arguments that is constantly brought up with the Tikka T3 action, is that there are no aftermarket parts, or quality aftermarket parts available for it. Well I’m here to tell you that is completely untrue.

Enter the LSS (Light Sniper System) from Modular Driven Technologies. It’s a chassis system that supports the Tikka T3 action and provides the user with the capability to use the renowned AICS magazines, as well as being able to use common AR-15 parts. Being able to run AICS magazines is a substantial improvement over the plastic, factory magazines. The magazine fits perfectly in the magwell and feeds flawlessly. I’ve had magwells in the past that were too tight, especially with a fully loaded 10-round magazine. I had no issues with the LSS while conducting reload drills with full and empty magazines. It has a traditional paddle style magazine release that is easy to utilize, even with gloves on, which is important for me since I now shoot in the snow regularly this time of year.


Although the stock is somewhat intended to be used in conjunction with collapsible AR buttstocks, it’s possible to purchase an adapter that allows you to utilize full length stocks, such as the Magpul PRS. I was a little concerned with running a collapsible stock since the barrel that I have on the Tikka was already about 26” (Remington Varmint Contour) and thought it would be too front heavy. Turns out that it isn’t that bad! The balance point is just in front of the receiver, and for me that’s definitely something that I’m able to work with.

Another thing that I was concerned with was being able to spot my shots. Even with that large brake on the end, I still lost the target in my sight picture with the old plastic stock and I knew this stock wasn’t exactly heavy either. The chassis body weighs in at 1.6 lbs, plus whichever buttstock and accessories that you choose to run. My entire rifle weighs in empty at 12.8 lbs, according to the bathroom scale. Compare that to most match rifles these days that weigh in excess of 18 lbs, the difference is noticeable. Despite being so light, I have no problem with keeping my target in my sight picture through recoil. Having that muzzle brake on there does help though! I’ve discovered that I really like running the collapsible buttstock, and the adjustability it provides. I run it one notch in from fully extended (6 position tube) for prone and any other type of shooting, and if I need to sling up, then I can fully extend it to maintain the proper eye relief without having to try and cheat back too much, especially in the cross-legged seated position. If you were to purchase one of the AR buttstock adapters that allows folding of the stock, you can easily turn this into a very stowable weapon system.


This brings me to one of the slight downfalls of this chassis. It has an extremely short handguard, to keep weight down I can only assume. When trying to utilize any slung position, my hand is stopped short of where I’m used to with other stocks. I noticed it didn’t affect me too much in the prone, but it did in the other positions. With that being said, I didn’t find the shorter handguard a hindrance while practicing barricades and other improvised positions. I would fold my bipod legs up and extend them all the way out (not all the time) and rest the rifle from there. I actually found it to be beneficial when running it off the bipods with it swiveling freely. This enabled me to make quick adjustments of the rifle’s cant to get my bubble level decent before each shot. Not perfectly bubbled up mind you, but at least in the ball park, depending on how much time I had for each shot. I know that sounds time consuming but it’s actually not, especially if you practice it and keep both eyes open while shooting.

Another feature that I enjoyed was the “steps” that they have machined into the side of the stock. I’m not sure whether this was intentional or not, but I found it to be a welcome benefit for those who choose not to wrap their thumb around the pistol grip. You are provided 2-3 positions in which you can place your thumb for a consistent reference point. As they say, consistency is accuracy. I personally find the “middle” position most comfortable for my hand.

I plan on putting another Tikka action in with this stock, with maybe an 18-20” barrel. I think that would make an ideal truck gun and a great option to take hunting. One thing to consider though for those of you out there that plan on carrying it while slung, is that most AR buttstocks have flush cups these days, while there is a sling stud on the handguard. This is easily remedied however by purchasing a sling stud flush cup adapter. Or, if you’re like me and have two TAB slings, one flush cup and one traditional sling stud, then you can simply mate the two and you’ll be in business.

To wrap things up, this is one of the most economical choices that a buyer can make for an aftermarket stock and especially for a chassis these days. It works even better for those of you that already have AR-15’s and the accompanying parts since you can install them  with ease and be out to the range in no time! Feel free to come check out the stock if you see me with it at the range or out at a match!
