Atlas Bipod PSR BT46-LW17

We purchased the Atlas Bipod BT46-LW17 as the bipod of choice for our MDT TAC21 20 inch Suppressed Modular Rifle project. We look forward to comparing the Atlas Bipod BT46-LW17 to our GG&G, Harris and BOBRO Bipods. While I typically  try to purchase as much as possible from Brownells this time around I went with Amazon because for an additional $3.99 I can have the bipod in hand next day and Im anxious to complete the project this week. Here is the Brownells link for those so inclined to support our efforts by visiting our sponsor.

 

For several years, Atlas bipods have dominated the tactical bipod market. The PSR model is the latest offering from Atlas and makes several key improvements over prior models. Fore and Aft pivot limiting bosses and strengthened leg bosses allow the PSR to adapt quickly to any position. The new Non-rotating legs feature internal construction of T7075 aluminum for increased rigidity when building a position. The Atlas PSR is the finest tactical bipod on the market.

MDT TAC 21 Remington 700 Chassis System

MDT TAC 21 Remington 700 Chassis System Inbound – As mentioned previously the first project at modularrfle.com is the “MDT TAC21 20 inch Suppressed Modular Rifle” project. We already have the Remington Model 700 SPS Tactical AAC-S on hand on now I am happy to report that the MDT TAC 21 Remington 700 Chassis System is inbound! Don’t be put off by the Brownells backorder status. I spoke with the fine folks at Modular Driven Technologies and they have tripled their production output on the MDT TAC 21 Remington 700 Chassis System.

MDT TAC 21 Remington 700 Chassis System Details

The MDT 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 strenth, 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.

Inherently the TAC21™ has a straightline 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.

MDT TAC 21 Remington 700 Chassis System Compatibility

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)
  • Savage Long Action, Models 110, 111, 112 and 116 (.300WM and .338LM)
  • 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.

 

MDT TAC 21 Remington 700 Chassis System Mounting and Compatible Accessories

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