Hey folks I just ordered the MDT ESS chassis for my tikka t3x my question is will the mdt polly mags work fine with this chassis or should I go with the steel ones? Do the mdt mags hold up well? I'm new to the chassis game and the ai pattern mags.
Tikka t3x in MTD ESS chassis question
- Thread starter TheM4chef

They're not as good as the magpul 10 rounders.
The mdt's have difficulty loading to a full ten rounds, and I found were more prone to jamming.
In my TAC21 I ran the steel AICS mags in 5 and 10 rounds using 178 gr. Amax bullets at 2.800" with no issues what so ever.
I have seen and handled the new ESS chassis, but I don't know if there is a change to the mag well dimensions.......
The first Gen 10 round MDT polymer mags did have an issue with fitting a full 10 rounds.The bodies were made short compared to the steel AICS mags. The 10th round was hard to load into the mag and the mag body would bulge making the mag very hard to insert or not fit at all. I used them as 5 rounders for reliability sake.
I believe MDT has corrected this issue with later runs of their polymer mags.

Steel mags work fine in my lss
Hello M4chef,
To clarify the situation with our chassis and magazines, the issue with the T3x is in the receiver cut-out, not our chassis. The T3 does not have this issue.
Some metal AICS pattern magazines will not insert fully into a T3x receiver. Our polymer magazines will, and Magpul AICS Pmags can be fitted, as can any metal magazine.
The ESS in Remington 700 Short Action has been tested and validated with;
- MDT Polymer 223/308
- MDT metal 5 and 10 round
- Magpul AICS Pmags
- Accurate Mag 10 rd 223/308
- Alpha 10 rd 308
- AI 10 rd 308
In addition, the magazine well of the ESS has been relieved, and our MDT polymer magazines will insert when loaded with 10 rounds.

What chambering is your T3 Varmint?
The T3 Varmint in 308 will work best with our 308 polymer magazines. Magpuls and metal AICS magazines will work with some fitting.
With 24 inch barrels the 15" for-end is the most popular choice.
Sorry to hijack but I have a question on mags as well. I am thinking of going with. A t3x Ctr (308) in its original stock for the time being.. I've been reading some posts online that say the mdt polymers will work in it. Is this true? Tikka mags are 180-220 bucks apiece. I hope it's true but wanted to confirm. Saw the claim on a few different boards
Poly mags will work but if you reload and like to seat longer you may have problems with them being to short for your bullet. I use the steel ones from Coretac Solutions for my .308 they'll except a cartridge out to 3.055" in length. If you don't reload......Nevermind...
Do these mags work for 308 without modifications?
