Please have a look at these FAQ's before sending a support ticket.


Do you ship internationally?

Yes we do ship internationally from our Canadian location. Note that each shipment is accompanied by an export permit from Export Controls Canada.

We recommend to first see if your country has any local dealers on our dealer locator page.

If you are unsuccessful finding a local dealer, you can order direct on our website, or contact us with your complete order, address and phone number. You will also need to complete an End User Statement form.

Please send your order, along with your import permit or End User Statement to [email protected].

How long will my shipment take?

Your order is processed andpacked for shipping as quickly as possible by our amazing order fulfillment staff. Depending on the items in your order or the volume of orders this could take one to two days.

When your order is packed and ready for shipping you will receive an email letting you know it will on it's way soon!

Regular shipping can take between 7-14 days - from order placement to final delivery.


Do you make a folding adapter?

Yes, we do! The MDT Folding Buttstock Adapter can be found here.

Can I use AR-10 or AR-15 magazines with your chassis?

A chassis (or bottom metal) does not determine whether you can use AR Magazines with a bolt action rifle. AR Magazines do not sit high enough against the bottom of bolt actions to make it feed properly.

There is only one Bolt Action rifle that allows the use of AR magazines, and that is the Mossberg MVP. In fact, they have a patent on this.

Therefore our Chassis for the Mossberg MVP are the only chassis we make that use AR magazines. All our other chassis use standard external box magazines.

Do you have factory seconds or clearance items?

From time to time we have products that marginally fail our QC checks due to blemishes or markings. If these markings do not inhibit the performance of our product we sell them at a discount on Black Friday.

Does the folding stock adapter work with the TAC21 or HS3 chassis?

Our folding adapters do work on our HS3, LSS, LSS-XL. But it does not work on our TAC21 or ESS chassis. Alternatively, the ESS Chassis System has it's own folding buttstock available here.

Note that these adapters cannot be used on an AR-15, or any system where the bolt travels back into the buffer tube.

Do you make a chassis for Mosin Nagant?

We have taken an extensive look at the Mosin Nagant action to determine whether the TAC21 or LSS chassis is a good fit for it.

Unfortunately our chassis systems are not a good fit for the Mosin Nagant, and at this time we have no plans to develop a chassis system for it.

Will my Savage rifle work with MDT Chassis Systems?

Savage has many different models - unfortunately, over the years, there have been minor changes that sometimes affect fit and function. We do however 100% guarantee our chassis to work in the following.

TAC21 Savage Short Action Chassis will work with:

  • Model 10, 11, 12 and 16 with the exception of model 12-Palma, 12-Fclass, 12-BenchRest.

TAC21 Savage Long Action Chassis:

  • Model 110, 111, 112 and 116.

LSS Savage Short Action Chassis will work with:

  • Model 10, 11, 12 and 16 with the exception of model 12-Palma, 12-Fclass, 12-BenchRest.

LSS Savage Long Action Chassis will work with:

  • Model 110, 111, 112 and 116.

We now also support Savage models with the bottom bolt release. The bolt release is accessible through the side of the trigger guard.

Will the TAC21 for Savage short action fit the Savage AXIS .308

It will not, it may be part of our plans sometime in the future, but is not part of our current project list.

We do make our LSS Chassis for the Savage Axis.

Will MDT Chassis Systems work with .300 WSM calibers?

Yes it will, using a .308 magazine. But only use metal magazines, which will allow you to bend the feed-lips out a little. Some people have made our polymer magazines work with this as well by shaving off some material. But we do not recommend this as it will weaken the feed lips.

What is the minimum Length of Pull on the TAC21 Savage Chassis with a Magpul PRS?

The minimum Length of Pull (LOP) on the TAC21 Savage Chassis with a Magpul PRS is 14.5". Our Skeleton Rifle Stock however comes in 2 different lengths, allowing you to get your Length of Pull down to 14", or our Skeleton Carbine stock as low as 12".

Can I use my 30.06 caliber Remington 700 in the TAC21 Chassis?

Yes, you will need a Long Action chassis. You can use .300WM magazines for the 30.06. The feedlips will need to be adjusted to fit this caliber.

Will the TAC21 Chassis work with a Remington 700 7mm?

Yes it will. You will need a Long Action Chassis using .300WM magazines.

Will any of the MDT chassis work with a Ruger m77 7mm long action?

No we do not produce a chassis for the Ruger Long Action M77.


What action screw spacing do you support for Savage Actions?

Our chassis do not list the action bolt spacing for our Savage chassis because, our chassis will accept both Savage actions lengths (4.27" & 4.40"). In the mounting hardware there is an off set washer which will accommodate both action sizes.

Which magazine do I use for 300 RUM?

There is no magazine for this caliber that works right out of the box. You can however use .338LM Magazines, and flatten, or mill out the front ribs.

Do you make a safety extension for the Remington 700 on the TAC21?

If you are looking to have a better handle on the safety with your Remington 700 on our TAC21 chassis, we do not make something for it, but we can point you in the right direction.

Magnum Mikes makes a safety extension for $34.99. Please see

Can I use a short action in a long action system?

The Long Action stock will not work with a .223. The .223 is a short action caliber. You can certainly swap the short action chassis between the .223 and the .308 actions. However if you are somehow able to use one of the Long Action magazines for your .223 or .308 ammo, you will be able to use the Long Action chassis.

What magazine can I use for my 7mm, .270, .280 or 30.06 caliber rifle?

This is a Long Action caliber. Using the TAC21 or LSS Long Action chassis systems, you can use the 300WM (.300 Win Mag) external box magazine.

For .300WM and 7mm the magazine can be used without modifications.

For the .270, .280 and 30.06 you will need to make some minor modifications to the feed lips (Bend in or out) to make your ammo fit properly.

Which magazine will work for Remington 700 in 300 Ultra Mag?

You can make it work with the 338 Lapua Magazine, but you would need to cut the rib out to make the ammo fit.

What magazine can I use for a Remington 700 chambered in 7mm Rem Mag?

You can use the 300WM with the Long Action TAC21 Chassis for the Remington 700 chambered in 7mm Rem Mag.
