I understand this gun is designed to shoot NATO pressure ammo. Gun may not cycle all .223 ammo.

The Duty Spec DT15 is designed for Duty Use. We designed and developed our rifle to shoot your defense and duty ammo without the over gassing you get from other commercial gun manufactures. This will allow you to use a suppressor without having to compensate with different springs. adjustable gas systems and buffer weights. Our guns will still allow you to shoot your training ammo, suppressed, unsuppressed and duty ammunition without having to do any special settings or changes to the weapon. Our barrels use port holes of of .071 giving you the optimum gas pressure. These guns will shoot some 223 ammo on the market but our Duty Spec Barrel shines with full power ammo. Paired with our 9.6 Mlok rail system. This rifle will come complete with 2 buffers so you can run suppressed more efficient.

5 of 5 Awesome December 9, 2020
Reviewer: biguy525 from Fort Mill, SC  
Just opened the box to inspect the upper I received. Wasn't sure what to expect. After handling it for a few seconds you could easily see and feel a quality upper. Not that I have handled hundreds of uppers, but this one shows quality and detail at the highest level I have ever handled. Being this is a Christmas gift for my son we probably won't get to test fire it until after the holidays,  can't hardly wait. When I need another upper there will only be one, Disruptive products.
