Here at AR15Discounts.com we work with a wide variety of machine shops and barrel manufacturers. When we come across a barrel maker we like, we will often decide to private label those barrels for resale under the NBS brand. We purchase these barrels in large quantities and then pass the savings on to our customers.
Why buy an NBS Brand Barrel:
- American Made – Sourced from a variety of Tier 1 Manufacturers here in the United States
- Quality Control – All barrels are manufactured under ISO-9001 or better quality standards
- MOA Guarantee – All barrels 16 and longer are guaranteed to hold 1 MOA or better using properly weighted match grade factory ammo and shooting from a rest.

1 dimple for gas block, very clean threads, nice snug anti rotation pin (mated with a San Tan upper + rubber mallet). Appears to be quality machining with a reassuring attention to detail even for a shortie like this
