FAB Defense RAPS Collapsible Stock - Mil-Spec/Commercial Buffer

The FAB Defense RAPS (Rapid Adjustment Precision Stock) delivers enhanced stability and customization for AR-15 platforms through its innovative dual-compatibility design. This collapsible stock system accommodates both Mil-Spec and Commercial buffer tubes without adapters, streamlining builds and reducing compatibility concerns. The integrated cheek rest and adjustable length of pull transform standard carbine stocks into precision-oriented platforms.

What Makes This Different

Unlike traditional collapsible stocks that require separate cheek risers or compatibility adapters, the RAPS integrates height adjustment directly into the stock body. The ambidextrous single-latch system operates from either side, providing faster length adjustments than dual-sided mechanisms. Polymer construction reduces weight by 2.3 ounces compared to aluminum alternatives while maintaining structural integrity under recoil stress.

Key Features

• Dual compatibility fits Mil-Spec (1.146" ID) and Commercial (1.168" ID) buffer tubes
• Integrated adjustable cheek rest with 0.5" height range
• Six-position length of pull adjustment from 10.5" to 13.75"
• Ambidextrous single-latch operation for rapid deployment
• Reinforced polymer construction with textured grip surfaces
• QD sling swivel socket compatible with standard hardware
• Anti-rattle design eliminates stock wobble on buffer tube

Field performance centers on the stock's ability to provide consistent cheek weld across varying optic heights. The integrated cheek rest eliminates the need for separate risers when mounting scopes or night vision devices. Competition shooters benefit from the precise length adjustment, while tactical users appreciate the ambidextrous controls during gear transitions. The polymer construction resists impact damage and temperature extremes from -40°F to 180°F.
