Noveske Bolt Carrier Group for 5 56 NATO 300 Blackout DLC Finish Black 05002854 UPC 840906138960
Product Description
The Noveske Rifleworks 5.56 NATO / .300 Blackout Bolt Carrier Group with DLC (Diamond-Like Carbon) Finish in Black (MPN: 05002854) is a premium, duty-grade full-auto profile BCG engineered for uncompromised reliability in hard-use AR-15 carbines and suppressed firearms. Iconic for its laser-etched Noveske Iron Cross logo on the ejection port side, this complete bolt carrier assembly delivers exceptional thermal tolerance, reduced drag, and effortless cleaning under severe firing schedules.
Precision CNC-machined from case-hardened 8620 steel, the carrier features a sleek, ultra-slick Black DLC coating. Diamond-Like Carbon treatment provides extreme micro-hardness, an exceptionally low coefficient of friction, and unmatched resistance against carbon fouling, heat degradation, and corrosion—eliminating the need for heavy wet lubrication in abrasive field environments.
The bolt assembly is precision-machined from Carpenter 158 alloy steel, shot-peened for fatigue resistance, and High Pressure Tested (HPT) / Magnetic Particle Inspected (MPI) to guarantee zero microscopic material defects. Outfitted with a properly staked Grade 8 fastener gas key, a heavy-duty extractor spring with an o-ring insert, and a durable firing pin, the Noveske 05002854 represents the gold standard for custom rifle builds, suppressor hosts, and duty-ready AR platforms.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits all standard Mil-Spec AR-15 upper receivers chambered in 5.56x45mm NATO, .223 Remington, .300 AAC Blackout, and .350 Legend. (Note: Features a full-auto M16 carrier profile to add beneficial mass for reliable cycling and lockup in both semi-automatic and full-automatic lower receiver configurations).
- Perform a complete firearm safety check: drop the magazine, pull the charging handle rearward, lock the action open, and visually/physically inspect the chamber to verify zero live rounds are present.
- Perform a field strip and clean the internal upper receiver channel and barrel extension lugs before staging the new BCG.
- Apply a thin layer of high-tier synthetic gun lubricant to the four contact rails on the carrier body, cam pin, and bolt neck.
- Ensure the bolt is pulled forward into the unlocked position within the carrier before sliding the assembly into the upper receiver cavity.
- Perform a manual function check by cycling the action fully to verify smooth cam pin rotation, flush bolt face lockup into the extension, and crisp firing pin drop.
