The Recce rifle was originally developed by US SEAL Team Armorers to provide SEALs with a lightweight modular carbine that had enhanced ballistic performance and utility over an issue M4. Matching the size of an issue SOPMOD, the Recce runs smoother and allows more agile weapons control, thanks to its mid-length gas system and extended handguard.
