FAB DEFENSE Shotgun Buttstock

July 13, 2012

To support police departments across the USA, Mako is now stocking an expanded line of more than 30 FAB products that can improve shotgun performance.

This series of shock-absorbing FAB DEFENSE buttstocks that are easily installed on Remington 870 and Mossberg 500/590 shotguns to help the operator handle the recoil from any round.

The advantages provided by FAB buttstocks include enhanced performance and versatility. Models offer rock-solid, one-piece, ergonomic design with integral pistol grip; built-in shock absorber; storage compartment for batteries or cleaning kit; a rubber buttpad that grips body armor; and multiple points of attachment for slings. There are ambidextrous folding and collapsible FAB buttstocks with instantly adjustable lengths to virtually custom-fit any size shooter and accommodate changes in clothing bulk.

Also available are optional M4 style aluminum buffer tubes and adjustable cheek risers that allow the use of optics and open sights while accommodating helmets and face shields.

All FAB tactical shotgun buttstocks have a non-slip texture and are manufactured from aircraft-grade aluminum, steel, and MIL-SPEC reinforced composite materials.

Maximum Shotgun Versatility

The wide range of FAB tactical accessories designed for Remington 870 and Mossberg 500/590 shotguns enables users to experience the highest levels of shotgun performance in all situations.

  • FAB AGR870-FKSB and AGM500-FKSB Buttstocks feature patented systems that provide the industry’s greatest reduction in perceived recoil.
  • FAB PR870 and FAB PR-MO Tactical Forends provide three strong platforms on which to mount any tactical FAB, or other brand, accessories having standard Picatinny mounting systems. The FAB BM-4 Quad Rail offers the same opportunity to Benelli M4 shotgun users.
  • FAB SH-5 Shotgun Shell Holder secures five extra 12-guage rounds at the ready, on your shotgun, for fast reloading. Extremely strong, rigid design, with easy Picatinny attachment and quick release.
  • FAB AGR870 and FAB AGM500 Pistol Grips allow the attachment of any M-4 compatible buffer tube for mounting M4 stocks. These grips mount at the correct angle for best recoil control.
  • FAB PLS and PLA Tactical Light Mounts provide ways to readily mount 3/4”, 1”, and 1-1/8” lasers and tactical lights, including the FAB SpeedLight Series which produces 100 to 120 lumens from a single CR123A lithium 3V battery and LEDs.

Baltimore SWAT Test and Evaluation

Recently, the Baltimore, Maryland, Police Department SWAT Team conducted tests with a FAB AGR870-FKSB Recoil-Reducing, Folding, Collapsible, Shotgun Buttstock. Here are excerpts paraphrased from the actual Baltimore SWAT report:

Important Operational Issues

  1. Multiple carry configurations
  2. Increased recoil reduction
  3. Decrease in target reacquisition time
  4. Increase in overall recoil management
  5. Ease of use
  6. Reduction in time for follow-on shots

Operational Testing and Evaluation

  1. Configuration Description
    Recoil-reducing folding buttstock and pistol grip on a Remington 870 shotgun…the system is ambidextrous…there is also a compartment in the buttstock for battery storage. The extendable stock can be adjusted to five positions and the stock heel is covered with a rubber recoil pad.
  2. Operational Test and Evaluation Objectives 
    Provide a side by side comparison of the Mako FAB and [another] recoil-reducing shotgun buttstock for the purpose of determining if either is superior during operational use. The test was conducted to compare the recoil reduction capability of the stocks and ultimately to provide the shooter with increased recoil management.
  3. Operational Test and Evaluation Events 
    Approximately 20 rounds of Federal Tactical Buckshot and 40 rounds of Federal slug ammunition were tested in both weapons systems. 

The second phase of testing was conducted from the 25 yard line with Federal Tactical Slugs…There was significant recoil reduction with the Mako FAB stock, which enhanced the overall recoil management and provided a reduction in the time needed to reacquire the target.

The final phase of testing was rapid fire of 35 rounds of slug ammunition from the 25 yard line. During this phase, there was a measurable amount of recoil reduction [using the Mako FAB stock], which led to an increase in recoil management, effectively reducing the time to reacquire.


Overall, the FAB DEFENSE stock provided significant advantages when using Departmental Slug ammunition. The use of this stock will provide the operator with a reduction in felt recoil and a significant increase in recoil management. These two factors will not only increase the accuracy of follow-on shots, but will also reduce reengagement time. This will dramatically increase the operator’s ability to reacquire targets for follow-on engagements and his overall ability to effectively conduct threat evaluation.

In addition to the recoil reduction advantage, the stock also provided the operator with multiple options for stock configuration and sling carry positions.
