The Battle Arms Development OIP Gen3 rifle (brand part no. OIP003) is a 16-inch ultralight AR in .223 Wylde/5.56 NATO that Battle Arms Development says weighs only 4.6 pounds. It is built around a skeletonized billet 7075-T6 lower and upper, a patented OIP buffer system, a titanium bolt carrier with an ArmorTi finish and a titanium Thumper compensator. New in Gen 3 are a user-configurable M-LOK carbon fiber handguard, a carbon fiber pistol grip and a titanium billet bolt catch. Battle Arms Development designed the rifle as an optics-ready carbine with a single stretch of Picatinny rail in the right spot for a red dot, for shooters who want the lightest rifle they can carry.

Key Specifications

• Chambering is .223 Wylde / 5.56 NATO, so it runs both common 5.56 and .223 loads.
• Barrel length is 16 inches in a 4150 chrome-moly pencil profile with a black nitride finish.
• Rate of twist is 1:8, a rate that suits the bullet weights most shooters run through an AR.
• The gas system is mid-length with an OIP titanium .625-inch gas block, a layout that smooths cycling.
• The muzzle device is a titanium Thumper compensator, which tames muzzle rise and keeps weight down.
• The weight is 4.6 pounds as Battle Arms Development describes the rifle, which is far below a typical AR.
• The handguard is a 15-inch carbon fiber free-float M-LOK rail, user configurable and light.
• The bolt carrier is a titanium M16 carrier with an ArmorTi finish, chosen for durability at low weight.
• The grip is a carbon fiber OIP pistol grip that weighs barely an ounce.
• The rifle comes with a 20-round aluminum magazine that is laser engraved.
