The Gen4 MODMAT PATROL SBF is the natural evolution of the super popular MODMAT SBF that was introduced in 2019 and the WARTIME SBF in 2021.  Like many COVID-era items that were born from supply chain disruptions, the WARTIME SBF was a collection of the best parts available at the time.  Now in 2023, those disruptions are gone for good and MODERN MATERIEL can finally re-introduce the entire PATROL SERIES including the SBF.

• Forged aluminum upper receiver with forward assist
