The Knights Armament 11.5 CQB Upper kit is the same upper on Knights Armament’s 11.5 MOD 2 SBR.  The 11.5in Mod 2 upper features a Knights Armament’s MOD 2 series 5.56 Nato barrel, a free float URX4 M-LOK handgaurd, and a 3-prong flash hider.  This Knights Armament 11.5 CQB upper is a drop in replacement compatible with any milspec lower receiver.

The KAC 11.5 upper receiver group is one of the most sought after CQB upper receivers on the market.  The 11.5 CQB Mod 2 upper is the perfect combination of ballistics, maneuverability, and rail real estate.  By adding barrel length and rail real estate the 11.5 CQB MOD 2 upper give the shooter a platform to better manipulate lasers and lights over traditional 10.3in setups. This upper is fielded by FBI, Secret Service, and other government agencies.

Barrel

This 11.5in 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.

Handgaurd

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.

Flash Hider

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 does not ring upon firing and is compatible with the KAC line of 5.56mm QDC Suppressors. **Please note the upper is pictured with a KAC MAMS brake.  This is does not come standard and would need to be purchased separately. The upper will ship with a KAC 3-prong**
