The FN15 SRP G2 in 5.56 NATO (brand part no. 36-100608) is a lightweight direct-impingement carbine built around a free-float 15-inch handguard with maximum rail space at the 12 o’clock position. FN America pairs a 16-inch button-rifled barrel with a 1:7-inch twist, a hard-chrome-plated bore and chamber, and a pinned low-profile gas block, and the rifle feeds from a 30-round aluminum-body magazine. The hard-anodized flat-top receiver carries a MIL-STD-1913 rail and M-Lok slots at the 3, 6, and 9 o’clock positions, and an M16-style bolt carrier is MPI-inspected for reliability. Among modern sporting rifles in the AR rifles category, the SRP G2 favors shooters who want a lightweight, optics-ready FN-built carbine.
