13.9 Duty Upper

$769.99

SKU 139-DUTY1 Category Tags , ,

Our 13.9″ Duty upper is an excellent option for our customers seeking the shortest possible barrel length for running a suppressor while maintaining “rifle” status with a Pin and Welded Muzzle device.

The pairing of the 13.9″ with a mid-length gas system and the Riflespeed Gas Control is one super reminiscent of the OG Colt Dissipators in feel. These uppers can be tuned right into where you nearly cancel recoil. Excellent back gassing can be achieved where you don’t get gassed out with a suppressor or just shooting lefty becomes ten fold better. We recommend H2 buffer and Standard weight Carbine Springs (White Springco) for the best balanced results.

Note: Stocked uppers are bare muzzle, selecting our options for pin/weld muzzle device is done when ordered, this is often done same business day or the following before upper ships.

Our 13.9″ Duty Upper is available without a pinned muzzle device so the buyer may choose their own and have it pinned by their local gunsmith or utilize the upper on a pistol lower. (ALL NFA RULES APPLY)

 

*We accept this upper as a “Backorder” Item. We are a small business and the Duty uppers are mostly “build to order” at this time (Winter 2022).  We may have some “in-stock” ready to ship or it’s already in production and can be expected with 2-3 weeks after ordering. We will keep you posted upon ordering, the customer will be able to contact us anytime to find out status.

In stock (can be backordered)
