The NBS 8.3″ 9mm M-LOK Complete Upper with LRBHO is an excellent choice for your next Pistol or NFA compliant SBR build. We started with the excellent New Frontier Billet PCC Upper Receiver which features a patented Last Round Bolt Hold-Open (LRBHO) mechanism. At the heart of the upper is an 8.3″ QPQ Nitride 9mm barrel w/ a tapered profile and a generous feed cone to ensure reliable cycling. We’ve installed a flash can which results in reduced concussion and perceived noise levels but that can easily be swapped for a muzzle device of your choosing or suppressor. The upper also features a QPQ Nitride Toolcraft Gen2 BCG with a durable M16 style extractor and a mil-spec charging handle. The popular NBS M-LOK Handguard features a full length top rail and M-LOK mounting slots on all sides.
Note: LRBHO function will only work with Glock style AR-9 Lowers.
This upper is backed by the NBS Limited Lifetime Warranty in addition to the AR15Discounts satisfaction guarantee. Purchase with confidence, install it, run it and if you aren’t happy for any reason, return it within 30 days for a full refund.

Ehh
The upper is very well made and I love the look of it, but after completing the pistol build I have yet to be able to fire a round. When I load the magazine and try to chamber a round it jams, the tip of the bullet goes into the barrel, but the casing gets stuck, tried multiple ammo manufacturers and still the same issue. Not sure what the issue is. But it’s been a stressful build to say the least.
