Your TRS AR-15 Upper Assembly meets or exceeds military standards. It's lighter and yet able to better handle the rigors of actual combat conditions.
Here are the specs:
16-inch barrel with carbine length gas system: By far the most dependable setup for handling the grit, grime, and stresses of combat.
M4 Barrel Profile: One tough barrel - capable of handling the extreme heat and stresses of fully-automatic fire.
1:7 twist rate: Able to stabilize heavier bullets like armor-piercing rounds.
"Bird Cage" Flash Suppressor: Mil-spec. Rugged, reduces carbon buildup, stays cleaner, and gets the job done.
Free-float handguard: Lighter with greater accuracy and more mounting options for optics and other accessories. Comfortable with the popular overhand “thumb-over-bore grip”.
M-Lok handguard with Picatinny rail on top: Allows you to mount grips, lasers, lights, bipods, and more.
7075-T6 Forged Aluminum: Harder is better and 7075-T6 is the hardest.
Matte Black Hard-Coat Anodized Mil 8625 Type 3 Class 2: This tougher matte anodized finish can take some serious punishment.
5.56 Bolt Carrier Group: Mil-spec... Black Nitride finish... case hardened 9310 steel... 4139 steel gas key with Grade 8 hardware staked into a milled valley (to ensure proper positioning)... hardened 4340 cam pin... and a military spec 8740 steel center-less hard-chrome firing pin. Top quality.
Bolt Assembly: Mil-Spec... case hardened 9310 steel... heat-treated and CNC ground for precision fit... components shot-peened and Manganese Phosphate or Black Nitride coated. Extractor 4340 steel, Manganese Phosphate coated... and mil-spec extractor spring/o-ring combo.
