Andro Corp Industries ACI-15 Halo Features The Andro Corp Industries ACI-15 Halo is chambered in 5.56 NATO and built on a gas-operated AR platform with a black anodized aluminum receiver and a Picatinny top rail for optic or accessory mounting. The 10.30 chrome moly vanadium barrel features a black nitride finish for outstanding durability a 1:7 twist optimized for heavier 5.56 projectiles and a 1/2x28 threaded muzzle fitted with an A2 flash hider that removes in seconds for suppressor attachment. The free-float M-LOK handguard keeps the forend slim and snag-free while accepting lights lasers and foregrips at any position along its length. For home defense shooters and suppressor enthusiasts who want more muzzle velocity and reduced flash signature compared to an 8 barrel without a significant increase in overall length the 10.30 ACI-15 Halo represents the ideal middle ground in AR pistol barrel length selection. The ACI-15 Halo ships with a Shockwave SBA3 pistol brace that supports a stable two-handed shooting grip and adjusts for shooter preference and the black A2 pistol grip delivers familiar AR ergonomics. The safety selector and mil-spec trigger provide positive repeatable operation and the ambidextrous controls accommodate both left- and right-handed shooters without modification. At 25 overall and 5.80 lbs the ACI-15 Halo is compact enough for vehicle storage and home defense deployment while providing meaningfully better ballistic performance than shorter-barreled 5.56 pistols. For shooters who want a capable well-equipped 5.56 NATO AR pistol with a suppressor-ready threaded barrel at an accessible price point the Andro Corp Industries ACI-15 Halo is available for sale at GrabAGun.
