Details:

If you’re looking for a sturdy AR-15 14.5" upper assembly, consider the 14.5” NX14 complete upper by Seekins Precision.

The Seekins NX Series upper receivers were appropriately named. Made to standards that go above and beyond Mil-Spec requirements, the upper receiver of the NX14 is designed to have a superior fit with a remarkable performance, time and time again.

What Makes The NX14 Complete Upper Better Than Others?

As with all other barrels by Seekins Precision, this match grade barrel chambered in .223 Wylde was passed through four separate quality tests. The barrel has a non-glare bead blast finish which then Armor Black coated to offer you the accuracy of a precision rifle and is easy to maintain.

The gas block is completely adjustable for optimal load tuning. The gas system and the bolt carrier group are both Melonite-coated to prevent corrosion and to keep the cleaning process quick and easy.

A 12” NOXs M-LOK handguard is included with the NX14 upper to enhance its functionality. The handy M-LOK slots and the full-length top picatinny rail permit full customization capabilities for the avid shooter. The NX14 complete upper is compatible with all Mil-Spec lower receivers.
