The Smith & Wesson M&P10 Sport Optic Ready is a gas-operated AR-10-pattern rifle chambered in .308 Winchester (brand part no. 11532). Smith & Wesson pairs a 16-inch 4140 chrome-moly barrel, 5R rifling and a 1:10 twist with a mid-length gas system and a mid-length handguard. The rifle leaves the factory without iron sights so you can mount the optic you actually want. It suits range work, hunting and general-purpose use where .308 energy matters, and the adjustable stock fits a range of shooters.

Key Specifications

• The chambering is .308 Winchester, a hard-hitting cartridge with a long record on game and at distance.
• The barrel is 16 inches of 4140 chrome-moly steel, a length that stays maneuverable without giving up much velocity.
• The barrel carries an Armornite finish inside and out, a nitride treatment that adds corrosion and wear resistance.
• Rifling is 5R with a 1:10 twist, a pairing that suits common .308 bullet weights.
• Magazine capacity is 20 rounds, and the rifle ships with one magazine.
• The rifle is optic ready with no factory sights, so a scope or red dot goes straight on without removing anything.
• A mid-length gas system with a Picatinny-style rail on the gas block keeps cycling smooth and gives you a mounting point for accessories.
• The muzzle carries an A2-style flash hider, which tames muzzle flash in low light.
• Controls are ambidextrous, with the safety selector, magazine release and bolt release usable from either side.
• The stock is adjustable, and the rifle is listed at 128.5 ounces, just over 8 pounds.
