Tactical TAC21 Part 2

ambrose-1106Man!  When you need a chassis to deploy, MDT has it for you.  Check out this review!

It has taken me three days to get into position.  Sometimes getting to a target is the hardest thing, but who volunteered for this?  Of course me!  Once I hit my spot, I went ahead and set up my bi-pod and scoped out the distance to where my “known” target would be.  I was not using a standard military rifle.  I had a custom Rem 700 SPS with the TAC21 rifle Chassis.  This chassis is like the Ferrari when it comes to Chassis.  The TAC21  allows your barrel to free float so that you can get the maximum effective accuracy in each round.  One of the best thing you can do with this chassis, is the removal of the butt stock so you can even customize the heck out of it even more!!  Yes MDT does sell some more accessories for that.  Or the chassis allows for you to add whatever butt stock you like.


Sorry, I got carried away there for a moment. Long story short, the target came into my window of opportunity and I took the shot.  Once, the target was down, I went back down the hill from where I was laying and high tailed it out of there.  Made my way to my extraction point, which was an old rock house down by a creek bed.  I took off the ghillies suit and set up a hide out back of the house.  Job well done and out of here!

One of the most important thing in the Sniper, EDM & DDM world is your rifle.  Building your first rifle with the TAC21 chassis has given me everything I need or excepted in a rifle.  (Check out Part 1 here)  My rifle put together only weight 8 pounds.  Yes 8 pounds of awesomeness!  Check out what MDT has to say:

ambrose-1091-2Looking for a stock replacement for your Remington 700, Savage or Tikka T3 Bolt action rifle, turning it into a tactical and highly accurate system?

Our TAC21 Chassis system for bolt action rifles offers a combination of improved accuracy, superior ergonomics and specialized design allowing use of AR-15 butt-stocks, grips and automatically converts your rifle to an external box magazine fed rifle.

The TAC21 can be installed in 30 – 45 minutes without the need of bedding and has proven results with up to 28% accuracy improvements.

Our TAC21™ chassis system a combination of benchrest accuracy, superior ergonomics and specialized design. This chassis brings the bolt action rifles to the next level in versatility and modularity, with an instant improvement in accuracy.

The chassis system is manufactured out of billet 6061-T6 aluminum, which has been hard anodized to mil spec type III for extra strength, and has been finished with Cerakote™ in Black or Flat Dark Earth (FDE).

TAC21™ chassis is engineered to minimize warping and distortion. The rifle receiver only makes contact with the TAC21™ chassis on the V shape bedding and recoil lug area insuring the best accuracy and repeatability. The generous clearance on the fore-end makes any barrel (diameter up to the receiver size – 1.350”), free floating.

TAC21 End CapThe end cap features a quick release lever which is tightly locked in place, allowing quick removal of the buttstock and bolt.

Inherently the TAC21™ has a straight-line design, meaning that the recoil comes straight back instead of making the front of the rifle kick upwards. This results in more accurate and quicker follow up shots. This also translates to a decrease in felt recoil and comfort.


The TAC21™ chassis system is currently manufactured for the following bolt action rifle platforms:

  • Remington 700 Short Action (.223 and .308 bolt faces)
  • Remington 700 Long Action (.300WM, .338LM, 7mm, 30.06)
  • Savage Short Action, Models 10, 11, 12 and 16 (.223 and .308 bolt faces)

  • Tikka T3 – Short Calibers (.223 and .308 bolt faces)
  • Tikka T3 – Long Calibers (.300WM, 6.5×55, 7mm, 30.06). Requires MDT 3.560 Magazine.
TAC21 Fore end mountingSlightly offset tapered holes ensure the fore end is pulled tight against the action housing


The TAC21™ chassis is designed to accept any AR-15 butt-stock and pistol grip (purchased separately), offering the option to customize from the wide variety of  Accessories available on the market.

The TAC21™ chassis uses external box style magazines in .223 and .308 caliber for Short Action and .300WM or .338LM magazines for Long Action rifles, and supports installation of bolt on MIL-STN-1913 accessory mounting rails on the fore-end and side of the action housing.
