This kit’s combination of lightweight, compactness, and power makes it the perfect multi-purpose entry weapon. The kit centers around a 16" fluted barrel HBAR 1x9 twist barrel. Fluting increases barrel rigidity and reduces the flex and vibration of the barrel, and also has the added benefit of significantly decreasing the weight of the barrel. With the superior stopping power of 5.56 ammo, this is an entry weapon that is, in many ways, superior to it's 9mm counterparts.
