M4 SOPMOD Telescoping Hydraulic Recoil Stock (Mil-spec)

The M4 SOPMOD Telescoping Hydraulic Recoil Stock (Mil-spec) assembly offers hydraulic felt recoil suppression for telescoping shotgun stocks. Replaces the buttstock assembly on all Mesa Tactical telescoping stock systems. CANNOT BE FITTED TO AR-15 RIFLES.

SKU: 92180



The M4 Carbine buttstock assemblies often ship from the factory in a “stuck” state that does not allow them to be adjusted. This is simple to remedy. Grab the buttstock with one hand and pull the adjustment lever away from the stock against the spring at a right angle to the receiver extension tube until you can pull the buttstock back
along the tube. To install the M4 Carbine buttstock included in Mesa Tactical stock kits, ensure the stock lock nut and end plate end are installed on the stock receiver extension tube.

Any Mesa Tactical telescoping stock kit can be upgraded with a hydraulic recoil buffer which replaces the receiver extension tube in our stock kits and reduces felt recoil. Purchase either a complete replacement M4 SOPMOD recoil buttstock assembly, or the “drop in” hydraulic buffer alone.
