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 level of success is nothing short of spectacular. A huge number of top competitive shooters have already switched to Micarta stocks, and more continue to 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 the description sounds counterintuitive at first.

Micarta is significantly lighter weight-wise than aluminum (about 20%), yet it deals with recoil much more effectively. It is a “dead” material with little resonance or vibration. The result is less felt and more manageable recoil, yet it weighs about 20% less than aluminum, which is the “counterintuitive” part.

We believe our company is the first to offer chassis made from Micarta, not traditional stocks, but chassis with all of their implicit benefits. And we are not merely offering “a chassis” but 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 (BipodeXt technology) and the action sitting area is now a single piece.

– Buttstock: Completely toolless adjustment of buttstock:

  • Length of pull
  • Rear bag rider elevation
  • Cheekpiece elevation
  • Buttpad elevation

These buttstocks can be adjusted in the field without tools. All the above-described features are included in our standard offering.

      • F.A.S.T. II Orca Mama chassis weight and weight supported:
        • Micarta Chassis weight: 12 lbs. 4 oz.
        • Maximum scoped and barreled-action weight: 40 lbs.
      • F.A.S.T. II Orca Baby chassis weight and weight supported:
        • Micarta Chassis weight: 10 lbs. 2 oz.
        • Maximum scoped and barreled-action weight: 30 lbs.
      • F.A.S.T. II Mako chassis weight and weight supported:
        • Micarta Chassis weight: 8 lbs. 8 oz.
        • Maximum scoped and barreled-action weight: 18 lbs.

F.A.S.T. I (one BipodeXt tube) and F.A.S.T.-Ready chassis weigh approximately 6 oz and 2 lbs less.
