Battle Arms Development manufactures an extensive line of high-quality firearms, parts, and accessories for the versatile AR platform. Their AR-15 Workhorse upper is chambered for 5.56 NATO and perfect for a do-all rifle build. The forged aluminum M4 upper receiver is paired with a 16" 1:7 A2 profile barrel manufactured from 4150 chrome moly vanadium. Its 1:7 twist rate produces outstanding results with heavier bullets, while lighter projectiles should be reserved for plinking or general recreational shooting. An A2 flash hider may not be the fanciest option but it's installed on standard 1/2x28 muzzle threads, so upgrade options are endless. This upper assembly also has a mid-length gas system to produce optimal reliability while softening the felt recoil impulse. Aesthetically it has a tough tactical look made possible by their Workhorse 15" free float handguard with plenty of M-LOK slots to mount your favorite accessories. Although it does not include a bolt carrier group or charging handle, this is an excellent opportunity to hand pick these components to meet your specific build needs and style. If you're looking to build a solid rifle that can handle any task thrown at it, Battle Arms' Workhorse AR upper is exactly what you're looking for.
