AR-15 16" 5.56/.223 BARRETT STYLE LIGHTWEIGHT UPPER ASSEMBLY / 15" MLOK

AR-15 upper assembly with a 16" 5.56/.223 barrel and a Barrett style lightweight design. 

Details about the individual components:

• Barrel: The barrel is 16 inches long and made from 4150 CMV steel with a 1x8 twist rate. It has a carbine-length gas system and is nitride coated for accuracy and durability. It is chambered in 5.56 NATO and features button rifling. The barrel has a .750 diameter under the gas block and 1/2x28 threads that are completed with a Barrett style muzzle brake and crush washer. It also has M4 feedramps, which aid in reliable feeding.

• Upper Receiver: The upper receiver is an A3 flat top design made from certified 7075-T6 aluminum forgings. It is black hardcoat anodized to government specifications and features a forward assist and dust cover installed. Like the barrel, it also has M4 feedramps.

• Gas System: The gas system includes a low profile .750 steel gas block and a carbine-length stainless steel gas tube. This system regulates the flow of gas from the fired cartridge to cycle the action of the firearm.

• Handguards: The handguards are Moriarti 15" rifle-length free-floating slim and light profile MLOK rails. They are made from aircraft quality aluminum and are black hardcoat anodized. The specific design of the rails may differ based on stock availability, but they are of the same excellent quality.

Overall, this upper assembly appears to be a well-made and reliable option for an AR-15 platform firearm.
