About CUR-15-A (AR-15, .223 WYLDE, 5.56)

We worked closely with a premium rifle manufacturer to bring you these solid complete uppers at a great price. Every part of this upper is proudly made in America!

The upper receiver is forged 7075 aluminum, precision machined on 5 axis mills, then hard coat anodized; they are the finest you can buy. These forged uppers are excess M4A4 uppers from a military contract with M4 marks above the gas tube.

The barrel is 16" and chambered in 223 Wilde which can shoot both .223 and also handle the increased pressures of 5.56. The 1 in 8 barrel twist is the best option for general purpose and long range shooting with the most common rounds available (learn more about twist rate below). The barrel is manufactured from 4150 chrome molly vanadium and then salt bath nitrided for the best accuracy, corrosion resistance, and lifespan.

The M16 profile bolt carrier group is machined, heat treated, shot peened, and then ground to exacting tolerances of +/-0.0005” for smooth operation (you will see and notice the difference). The bolt is 9310 steel with a MIM extractor, shot peened, nitrided, and magnetic particle inspected. The firing pin is precision machined, heat treated, ground, then chrome plated per the mil-spec.

The 15" MLOK handguard has a lightweight and comfortable design with the interrupted rail and is machined from a 6061-T6 aluminum extrusion and then hard coat anodized. The design also features a reinforced anti walk lock-nut that prevents rail movement and also anti-rotation tabs that cradle the upper receiver.

The mil-spec charging handle is machined from 6061-T6 aluminum and then hard coat anodized. We also include our Finger Stop and our Large Barrel Thread Protector so you can leave it or easily unscrew it and replace it with a muzzle device of your choice.

These are complete uppers with BCG's and charging handles, and test fired to ensure you receive an excellent working upper. Again, these are not uppers assembled by someone in their garage or by some unknown company. These are fully machined and built in-house by a premium rifle manufacturer who is a major OEM builder for many top-tier brands. We worked with them to buy in bulk to offer our customers a truly great upper at an affordable price.

More information about twist rate:
Considering barrel length and bullet velocity, we feel this is the best option for general purpose and long range shooting with the most common rounds available. Many manufacturers choose a faster 1 in 7 twist which can cause accuracy issues with lighter 55-grain bullets by exaggerating tiny imperfections in the bullet when it spins too fast. The 1:8 twist rate is ideal for M855 62-grain “green tips”, but still stabilizes lighter 55-grain bullets well.
