The Radical Firearms RPR SOCOM in .223 Rem/5.56 NATO (brand part no. FR16556SOC15RPRCO) is a semi-automatic AR-15 built in a restrictive-capacity 10-round configuration, pairing a 16-inch chrome-moly-vanadium threaded barrel with a fast 1:7-inch twist rate. Radical Firearms builds this rifle on mil-spec upper and lower receivers with a 15-inch RPR free-float rail for accuracy and cool handling, and fits a B5 Systems Type 23 pistol grip with a 6-position B5 Bravo stock over a carbine mil-spec buffer tube. An A2 flash hider caps the muzzle. Among AR-platform rifles in the AR rifles category, the RPR SOCOM favors shooters in restrictive-capacity states who want a mil-spec-pattern 5.56 AR.
