Will this work on a shockwave with SBA4 brace.

I did not purchase the kit since I already had the adapter. The hydraulic tube does work with the SBA4 brace though, that’s how I set up my virgin 870 receiver. So it should fit.

Product Info for KynSHOT Tactical Shotgun Conversion Kit

KynSHOT Shotgun Conversion Kits typically take less than 15 minutes to completely install using only ordinary hand tools. Kits include a Hydraulic Recoil Buffer, stock adapter, all hardware needed to mount the buffer, an armorer's wrench, and a complete instruction set.image

KynSHOT offers a revolutionary damping selection feature that allows you to choose from one of three damping settings - light for lighter loads, medium for normal shooting, and high for higher power rounds.

The KynSHOTâ„¢ hydraulic buffers reduce recoil, muzzle rise, and shoulder fatigue allowing for quicker target acquisition after the trigger is pulled. In addition, these AR15 Recoil Buffers reduce excessive wear and tear on the mechanical cycling components.

KynSHOT hydraulic buffers are manufactured with premium seals, materials, and components in an aerospace-grade manufacturing facility that is dedicated to quality. Each and every one of their product designs have undergone extensive impact, functionality, and life testing to ensure unmatched performance. This results in a product that can withstand and perform in harsh environments, including temperatures from -30°F to 150°F. The patented design and damping technology make the KynSHOT buffers the industry-leading recoil mitigation buffer.
