Precision machined from heavy duty 4150 Chrome Moly Vanadium Steel, this barrel features a 6 groove button rifled bore to ensure consistent accuracy, with a 1:8 twist rate optimal for a variety of bullet weights. The mid-length gas system is designed for reliable and smooth cycling.

Designed by Diamondback Barrels Co., this barrel also features M4 feed ramps and is compatible with a wide range of AR-15 parts. The medium contour/profile of the barrel provides a good balance of weight and heat dissipation.

I love these barrels!! I just bought my 2nd. Nice finish, they shoot great. Definitely buy one.

Work great

I have used about 20 or more of these to build ARs to sell. They seem to work great. They need to be cleaned really bad when you get them but after they are nice and shiny. I would recommend these to anyone. I wish PA had more of the carbine length barrels from Diamondback. I love those.

Great for budget builds

I have two of these barrels. Both are functioning great with decent groups. Great for a budget build you plan on running into the ground and using cheap steel cased ammo. Can’t beat the price when on sale. Didn’t have any issues with the gas port being misaligned. Bought my barrels a year apart waiting for the next sale. No gas block dimple though.

working great

would love to get some more at that price

Awesome deal

This barrel is everything you wanted in a budget build. Works well, over 500 rounds through it and going strong ! I will purchase another one soon.

Diamondback 16" Barrel

Accurate with all 55 gr ammo I tried. MOA with poly tip bullets. A little under gassed with a .076 gas port. Drilled it out to .082 to get it to cycle properly.
