AR15 / M16 A3 Complete Parts kit LESS lower receiver, with 16inch M4 contour barrel (.310 bore) and A3 Upper receiver. Item # AR-RKM4A3762.
M4 Feed Ramp barrel extension
T-Marked forged upper receiver
1-10" twist, 6 grooves, right hand
11595E Barrel steel
Manganese Phosphate finish barrel
This 7.62x39 caliber barrel is 16" long, threaded the standard 1/2 x 28 tpi, and has an A2 flash hider with the correct crush washer. The barrel has a forged A2 front sight base with bayonet lug, not the cheaper cast front sight base which can break. It sports M4 contour and length cool tunnel handguards, and a correctly sized gas port for reliable function. The barrel is machined from chrome-moly, high vanadium steel and hardened to a U.S. government Mil-spec of Rc 26-32. The barrel, and all external steel parts, are manganese phosphate finished IAW 220.127.116.11 of Mil-STD-171, the U. S. government's recommended protective finish for steel. This finish not only looks great, it affords complete corrosion protection. These barrels are of Mil-spec M4 contour (.750 under the front sight base) complete with the M203 groove in the front. This contour is the perfect balance between light weight, heat dissipation, and accuracy. The barrel is button rifled with 6 grooves, right hand, 1 / 10" twist. The 1/10" twist is best for this caliber because it handles the widest variety of ammunition and bullet weights. The barrel is mounted on a FORGED A3 upper receiver with built in Mil-spec M1913 Picatinny accessory rail, with the correct rail numbers engraved, made from certified forgings, hardcoat anodized IAW Mil Spec A8625, Type III, Class II, black per No. 37038, Table IX with nickel acetate seal, as per the Mil-spec. The upper features a forward assist and hinged ejection port cover.
The buttstock tube is the mil spec thickness (1.145" OD) M4 buttstock (not the cheaper carbine buttstock). This buttstock features 6 positions for maximum shooter comfort, reinforced honeycomb; design for heavy duty use.
All semi auto lower receiver parts are INCLUDED as well as semi auto bolt, carrier, and charging handle. The upper is COMPLETELY ASSEMBLED, and HEADSPACED. Each and every part to the gun is included EXCEPT the stripped lower receiver! (A complete firearm is pictured, the lower receiver and 7.62x39 magazine, even though shown in the picture, are NOT included)
