Luth-AR 11.5" Government Profile Complete Upper 5.56x45mm 1:7 Twist

Luth-AR 11.5 Government Profile Complete Upper Features The Luth-AR 11.5 inch Government Profile upper is built around a 4150 steel barrel a material chosen for its durability and ability to withstand sustained firing without premature wear. The 1 in 7 twist rate stabilizes a wide range of bullet weights in 5.56 NATO giving builders flexibility in ammunition choice from lighter varmint loads to heavier longer-range projectiles. The button-broached rifling process used on this barrel is known for producing consistent accuracy at a more accessible price point than hammer-forged alternatives. An F marked front sight base is included keeping sight height correct for use with standard AR-15 sight systems and co-witness setups. The A3 flat-top upper receiver provides a full-length Picatinny rail for mounting optics and the included bolt carrier group and charging handle make this a genuinely complete ready-to-install upper assembly. A 2-piece carbine-length handguard covers the barrel and gas system simplifying installation while giving the rifle a classic clean appearance. The manganese phosphate finish applied to the upper and barrel assembly provides reliable corrosion resistance for a rifle that will see field and range use. The threaded muzzle accepts standard 1/2x28 muzzle devices letting builders add a brake compensator or suppressor mount. The Luth-AR 11.5 inch Government Profile Complete Upper is available for sale at ARMSAGORA for builders assembling a reliable classic-profile AR-15 pistol or SBR.
