USED CMMG MOD4SA / DPMS .223–5.56 Stainless Fluted Heavy-Barrel Rifle

This custom-configured .223 Remington / 5.56 NATO semi-automatic rifle pairs a CMMG MOD4SA lower receiver with a DPMS upper assembly and a long stainless-steel fluted barrel. The CMMG lower uses the familiar AR-pattern control layout and is fitted with a fixed stock and standard pistol grip. CMMG’s AR-15-pattern lower receivers are built around a forged aluminum, mil-spec-compatible design.

The upper features a free-float-style tubular handguard, raised Picatinny optics rail, and a stainless fluted barrel marked DPMS .223 1-9. The 1:9 twist rate is a versatile choice for many commonly available .223 and 5.56 projectile weights. Its long, heavy-profile barrel and rifle-length configuration make this setup best suited for bench shooting, varmint hunting, and recreational target work rather than lightweight field carry.

Based on the photos, the rifle is in good used condition with visible handling marks and light finish wear on the stock, receiver, and handguard. It includes one detachable magazine
