PMT-9 Billet 9mm 5.5" Complete Upper

(No reviews yet) Write a Review


These complete uppers have been assembled. They are ready to ship and are plug and play. Our AR9 uppers are built with a 5.5” barrel that highlights precision accuracy over other brands.


Billet CNC uppers are also made from 7075-T6 aluminum. Built to run and be abused. These are our dedicated AR-9 Uppers and do not have a forward assist or dust cover.


The upper receiver is paired with a 7” 6061-T6 CNC machined billet handguard. The MLOK handguard features superior tensile strength and is designed to endure heavy impact without throwing your iron sights or optic out of alignment. The handguard mates direct to the upper and features anti-rotational tabs. The handguard is installed using our steel low profile barrel nut which requires no timing as it fits under the gas system.


The 5.5" barrel is produced from raw bar stock to finished product. The barrel is properly stress relieved after rifling, and extensions are torqued after nitride. Superior quality control system ensures that all barrels are dimensionally correct and bores fall well within their individual tolerance.

We used a 3.3” Blast forward flash can device instead of a muzzle brake. This will divert all gas forward removing any gas blowback onto the operator. This makes for a comfortable shooting experience that is ideal for short barrel systems, especially in the home defense application. The flash can combined with the barrel makes an overall combined length of 8.8”

Charging handle is manufactured by BRACE BUILT. CNC manufactured ambidextrous charging handle that looks outstanding and has a smooth operation.
