AR-15 300 AAC Blackout 16" Carbine "BLACK CANON" Upper Assembly

Experience reliable firepower and sleek styling with the Moriarti AR-15 300 AAC Blackout 16" Carbine Upper Assembly – Black Canon Edition. Built for states like California and New York, this upper is designed for compliance while still packing performance and precision.

The 16" medium profile barrel is heat-treated, black nitride finished, and precision rifled at a 1:7 twist, giving you stabilized accuracy with subsonic and supersonic rounds alike. Topped with a flush-fit 6" mock muzzle brake (the “black canon”), this upper maximizes barrel length appearance and improves recoil control while maintaining legality in restrictive states.

The 15” rifle-length M-LOK free-float handguard provides ample space for lights, bipods, and grips, while the 7075-T6 forged upper receiver completes a durable, reliable build ready for any mission—tactical, defensive, or hunting.

I was happy with what I got for the price. I got to shoot a few with out any sights so I wasn't accurate, but seems to be a solid build. When it was delivered I wasn't home and it rained. They had it wrapped well and a lot of oil on it so no rusting there. For my next on I was thinking .50 Beowulf or the .458 socom.

I received my upper yesterday and shot it today at the range. It replaced my 7.5 inch .300 blk out upper. I love the look and feel. Recoil is smooth and is much more quieter than my short barrel. Delivery took only 14 days. I am impressed with my Moriati upper.

To be honest, I didn't know what to expect out of a $200 .300 Blk upper. I was ready to accept mediocre accuracy and less than perfect reliability, but my first range session was awesome. The upper is installed on my Sig M400 lower and uses its bolt carrier group. I only had a chance to shoot it at a 25 yard range, but the accuracy was excellent and reliability was perfect with 100 rounds of cheap Magtech ammo. Of the 100, 50 were 123gr supersonic and 50 were 200gr subsonic. The rifle worked well both in slow fire and rapid using a mix of Magpul, ASC, and Troy mags. Overall, I'm very happy with my Moriarti upper. Functionally, I couldn't ask for more. I'll definitely recommend your company to my friends and come back when I'm ready to buy my .450 Bushmaster upper for my rifle.
