Introducing the PRO line of Baby Orca chassis. Many PRO models are in stock, and many more are added every week. These are the PROs' salient features:

  • On average, 1.7 lbs lighter by weight (depending on action brand and model)
  • Larger barrel channel widths (ready for TACOM HQ structured barrels)
  • Refined Adjustable Rear Bag rider (finer and smoother adjustments)

These chassis are not just new products; they set new, higher standards. NEW MATERIAL: G10/FR4, a.k.a. Micarta. We are so confident in Micarta's characteristics that we will not create aluminum versions. Please see below for more about Micarta. These new chassis are presented in three different lines:

  • Makos - actions diameters up to 1.35"
  • Baby Orcas - actions diameters from 1.35" to 1.6"

Scoped and barreled actions maximum supported weights:

  • Mako F.A.S.T. Ready (no BipodeXt tubes) = 20 lbs.
  • Mako F.A.S.T. I (one BipodeXt tube) = 15 lbs.
  • Mako F.A.S.T. II (two BipodeXt tube) = 12 lbs.
  • Baby Orca F.A.S.T. Ready (no BipodeXt tubes) = 40 lbs.
  • Baby Orca F.A.S.T. I (one BipodeXt tube) = 35 lbs.
  • Baby Orca F.A.S.T. II (two BipodeXt tubes) = 30 lbs.

We are not supposed to discuss other companies here, but credit is due where credit is due. We know of at least one American stock manufacturer that has been making stocks from Micarta since 2016. That company’s success has been nothing short of spectacular. A large number of top competitive shooters have already switched to Micarta stocks, and more continue to make the switch every day. There must be a reason for that level of success.

It is a bit difficult to describe the benefits of this material because, at first, the explanation sounds counterintuitive.

Micarta is significantly lighter than aluminum, by about 20%, yet it manages recoil much more effectively. It is a “dead” material with practically no resonance or vibration. The result is less felt recoil and more manageable recoil, while weighing about 20% less than aluminum. That is the counterintuitive part.

We believe our company is the first to offer chassis made from Micarta. These are not traditional stocks, but full-featured chassis with all of the benefits that come with a true chassis system. And we are not merely offering “a chassis.” We are offering an Orca of a chassis.

Why “Orca”? Because of the similarities between the magnificent marine mammal and our chassis. They are both:

  • Beautiful
  • Nimble
  • Resilient
  • Lethal
  • F.A.S.T. — pun intended

Other key features of these chassis include:

  • Monolithic Chassis/BipodeXt: The proprietary fore-end that houses our renowned telescoping carbon fiber tubes, using BipodeXt technology, and the action sitting area are now a single piece.
  • Adjustable Magazine Latch: Our repeater chassis come fitted with our Adjustable Magazine Latch.
  • 3.725" and 3.850" CIP magazines in the same chassis: All chassis designed to accept AICS SSSF magazines can take either magazine length through the installation or removal of our exclusive patent-pending Spacer. The barreled action does not need to be removed to install or remove the Spacer.

Toolless buttstock adjustments include:

  • Length of pull: 13.5" to 15.5"
  • Buttpad vertical elevation: 4.2" of adjustment
  • Rear bag rider elevation: 1" of adjustment
  • Cheekpiece elevation: 2" of adjustment
  • Cheekpiece fore and aft adjustment: 2"
  • Modular cheekpiece system. Cheekpieces are available in:

    • 0.8" height, ships standard
    • 1.5" height
    • 2" height
  • Modular bag rider feet system. Feet are available in:

    • 5" length, ships standard
    • 6" length, with the extra 1" length installed fore or aft
    • 5" tilted, with tilt installed fore or aft — 180 MOA
    • Feet replacement requires a 5/32" hex key, which is included in the box.

Shoot better:

  • Experience steadier crosshairs
  • Mitigate recoil
  • Manage reduced recoil more effectively
  • Reacquire your target faster
  • Spot your own shots
  • Correct cant through the rotating tubes — lock your bipod and leave it alone

Still not sure about Micarta?

  • Thirty-day, no-questions-asked money-back guarantee. Take it out, shoot it, and love it. If you do not love it, send it back for a full and prompt refund.
  • We offer a Limited Lifetime Warranty. We will repair or replace your Micarta chassis for free if anything goes wrong.
