Details

The Davidson Defense Marathon 14.5" 5.56 NATO AR-15 Pistol Complete Upper is built for durability, reliability, and performance. It features a 14.5" M4 profile barrel made from 4150 CrMoV steel with a Parkerized finish, a 1:7 twist rate, and 1/2x28 threading—ready for the user to add and pin/weld a muzzle device to meet the 16" minimum barrel length requirement. The upper receiver is machined from 6061-T6 aluminum with a Type III hardcoat anodized finish for added wear resistance. A 0.750 gas block and carbine-length gas system ensure smooth operation, while the included nitride-finished 9310 steel bolt carrier group delivers long-term durability. Finished with a lightweight, aircraft-grade aluminum M-LOK handguard, this complete upper offers a high-performance foundation for any AR-15 build.
