TRYBE Defense Low-Mass AR-15 5.56 Complete Bolt Carrier Group BCG Black Nitride

TRYBE Defense Low-Mass AR-15 5.56 Complete Bolt Carrier Group BCG Black Nitride. High-Precision. Tuned for Gas Optimization. Drop ounces not performance. The TRYBE Defense Low-Mass AR-15 Complete Bolt Carrier Group is a precision-engineered BCG optimized for reduced reciprocating mass faster cyclic rates and improved recoil management in tuned AR-15 platforms. Built for shooters who demand faster cycling reduced recoil impulse and uncompromising durability under high round counts and harsh conditions. The bolt carrier is CNC-machined from AISI 8620 steel selected for its core hardness tensile strength and fatigue resistance. The reduced-mass geometry includes lightening cuts and skeletonization to bring the carrier weight to approximately 8.8 ounces a 25 30percent weight reduction from standard M16-profile carriers. The bolt is constructed from AISI 9310 steel offering enhanced toughness and superior fatigue resistance compared to traditional Carpenter 158. Each bolt undergoes shot peening magnetic particle inspection (MPI) and high-pressure testing (HPT) to ensure structural integrity under high round counts and adverse firing conditions. Each unit is QPQ nitride treated for extreme surface hardness corrosion resistance and smooth low-friction operation even in suppressed setups. Available in your choice of high-performance finishes including Black Nitride Nickel Boron Gold Titanium Nitride and PVD each variant offers a distinct balance of lubricity corrosion resistance and eye-catching appeal. This lightweight BCG is optimized for use with adjustable gas blocks tuned buffer weights and reduced-power recoil springs enabling shooters to fine-tune cyclic energy and bolt velocity. Ideal for flat-shooting competition rifles suppressed builds or any system requiring precise control over gas and inertia forces. Whether you're dialing in a race gun or fine-tuning a lightweight duty rifle the TRYBE Defense Low-Mass AR-15 Complete Bolt Carrier Group is engineered for anyone demanding faster cycling and less recoil impulse.
