You’re looking at the NBS 8″ 9mm Medium Profile QPQ Nitride Barrel. We sell hundreds of varieties of barrels from many top manufacturers and the ones we like the most end up as NBS barrels. We buy these in large quantities and re-brand them so we can bring them to our loyal customers at a fraction of the cost.
These 8″ 9mm Barrels feature a Straight profile and have been cut from high quality 4150 Green Mountain Rifle barrel blanks and are machined to have a generous feed cone which ensures consistent feeding and further enhances reliability. The barrels are then finished with a uniform jet black QPQ Nitride finish for easy cleaning, corrosion resistance and extended service life.
NOTE: Because blowback / pcc barrels do not have a barrel extension, you will consider this barrel 7.5″ long when measuring for a handguard.

Perfect 9mm Length
Makes a great all around option for a 9mm Pistol/Carbine build...not too long, not too short. Delivers full ammunition velocity to provide more than acceptable mid-range accuracy out to 100 yds for a pistol caliber.
USGood product
Quick and fast shipping. Put the barrel on AR pistol 7 inch rail sits just in front of the muzzle brake. Barrel measures like a regular 7 1/2 inch barrel.
USGreat Budget AR9 Build- With one caveat
So far, so good. Feeds well and feels solid. Only con is it doesnt have the pin on the barrel to keep it from spinning on the upper. Shouldnt matter without a gas block, but it did bother me enough to take away one star.
