The Knights Armament 14.5 Mod 2 Upper kit is the same upper on Knights Armament’s 14.5 MOD 2 Carbine. The 14.5in Mod 2 upper features a Knights Armament’s MOD 2 series 5.56 Nato barrel free floated inside a URX4 M-LOK handgaurd with a 3-prong flash hider. This Knights Armament 14.5in upper is a drop in replacement compatible with any milspec lower receiver.
As LPVO’s continue to advance the 14.5in upper is increasingly becoming more and more popular for its relatively small footprint while retaining ballistics capable of making mid range shots. The Knights Armament 14.5 Mod 2 upper provides the perfect foundation for the “do all” rifle.
This 14.5in chrome lined barrel features KAC’s improved E3 round-lug bolt design. The improved E3 round-lug bolt design both enhances reliability during function and increases bolt life far beyond the industry standard. This is especially crucial for shooters operating their weapons in harsh environments or under increased pressures with a suppressor. Combining the E3 bolt design and machine gun grade chrome lining this is arguably the most durable barrel on the market.
The URX 4 handgaurd is a slim line free float design featuring M-LOK Mounting slots stretching the entirety of the rail system. However, what makes the URX4 and MOD 2 system unique is the fact that there is not a separate barrel nut that the rail then attaches to. The URX4 is the barrel nut and inetrates the rail system in a one piece design. This provides industry leading durability and the perfect host for laser devices and front sights. Because the rail itself is the barrel nut, rail shift on the barrel nut is eliminated, eliminating zero shift.
The KAC 5.56mm 3-Prong Flash Hider interferes with propellant gas combustion forward of the muzzle to significantly reduce flash signature. This 3 prong flash hider will not ring upon firing and is compatible with the KAC line of 5.56mm QDC Suppressors.
