Noveske Chainsaw 556 16" Mlok Upper
The Noveske Chainsaw 556 16" M-LOK upper receiver is built for shooters who want proven Noveske quality without compromise on durability or practicality. This complete upper pairs a forged 7075-T6 aluminum receiver with a 416R stainless steel barrel, delivering the kind of hard-use reliability that Noveske has earned across professional and civilian platforms. The Chainsaw line represents Noveske's utilitarian approach: honest engineering, individual quality control, and accessibility at a more reasonable price point than their premium offerings.
The 16-inch barrel profile works well for intermediate-range precision, hunting, or tactical applications where barrel length balances velocity and handling. The 1:7 twist rate stabilizes a broad range of 5.56 NATO ammunition, from lighter practice loads to heavier match rounds. Mid-length gas tube tuning keeps the action smoother than carbine-length systems while maintaining compact proportions. Noveske hand-polished the feed ramps on both the barrel extension and upper receiver to ensure reliable feeding in any condition—a detail often skipped at this price tier.
The gas block is forged Noveske design, low-profile at .750" journal, pinned directly to the barrel for zero shift. Threading on the muzzle is the standard 1/2"x28 pattern; the included A2 birdcage flash hider is a classic choice, easily swapped for your preferred brake or suppressor adapter. Hard-coat type III anodizing protects the receiver from corrosion and wear. Every Chainsaw upper ships with an individually serialized barrel, a mark of quality control that matters when you're assembling a rifle you depend on.
M-LOK mounting across the handguard gives you modern rail flexibility without the weight or bulk of Picatinny—ideal if you're building a lightweight hunting upper or a truck gun that doesn't need every rail packed with gear. This is a no-nonsense upper for shooters who know what they want and aren't interested in hype.

Frequently Asked Questions
Will this upper work with my AR lower receiver?
This is a complete upper assembly that will mate with any standard AR-15 lower receiver. Just make sure your lower is in 5.56 NATO or .223 Remington and uses mil-spec dimensions.
What is M-LOK, and do I need special handguard attachments?
M-LOK is a modern mounting standard that uses slots milled into the handguard instead of full Picatinny rails. It's lighter and cleaner-looking than quad rails, and accessories designed for M-LOK attach directly via T-nuts and bolts. M-LOK gear is widely available and often easier to position exactly where you want it.
Is this upper good for hunting?
Yes. The 16-inch barrel and 1:7 twist work across a wide velocity and bullet-weight range in 5.56 NATO, making it suitable for medium-game hunting where local law permits rifle-caliber centerfire rounds. The mid-length gas system and hand-polished feed ramps ensure reliable feeding and cycling.
What's included with this upper?
You receive the complete assembled upper with the barrel, receiver, gas system, low-profile gas block, and A2 birdcage flash hider installed and ready to attach to your lower receiver.
