This gun is an ambidextrous bullpup – that is the extent of its similarities with the P90. THe clip is stored on the bottom back half of the gun as oppossed to the upper front half (P90). The rounds for this gun are also in line with the barrel, the rounds for a P90 are stored perpindicular to the barrel. Whats more, the spent casings are sent up and forward of the rifle. The P90 sends them straight down. Last – the P90 uses one of the absolutely smallest production center-fire rifle cartridges where this one is firing the upper limits of practicality. Only a 30-06 would be larger (only by a little bit) before you started getting into .50 BMGs- which is so large that it is practically an anti-matter round.

I am certain that this gun, like any other blow-back, can be configured to a full-auto. But a full-auto .308 hasn’t really been done since the BAR in WWII. The BAR weighs in at 20 pounds, reasonable in combat, but terrible to carry. Remember in “Saving Private Ryan” when Tom Hanks asks Ryvan, “Where’s your BAR?” Ryvan responds, “Bottom of the channel – bit** tried o drown me.” That thing is a brick, but it NEEDS that weight to keep it managable on a full-auto fire with a round like a .308. The P90, on the other hand, with its diminuitive bullet, will work best when it is at a higher rate of fire – it needs a couple of rounds at least to do the damage of 1 round of .308 ammunition.

Still, I have wondered to myself if Kel-Tec is making a move for military contracts with this gun. I have read that it is going to be offered in a 5.56, a 6.8 SPC, and a 6.5 Grended in addition to the already mentioned .308. Excepting the .308 (which is dual purpose round) all of the other rounds are almost exclusively military. That and the fact that so much effort was made to create a rifle which is truly ambi-dextrous – it seems clear that military contracts are EXACTLY what this gun is intended to fill.

Finally, throw in the accelarted sells of GLOCK 18′s to our special forces units and military and contractor units in Iraq, and we can see that there is indeed a niche for this rifle. GLOCK 18 sells have ramped up because our troops are finding that a full-size battle-rifle can be cumbersome and unwieldly when called up to perform urban assault and door-to-door corridor work in an urban setting. The GLOCK 18 with its 18 round per second and compact frame still allow for a great deal of stopping power while still keeping the weapon compact enough that corridor work isn’t out of the question.

Mantaining the effective range and power of a battle rifle while increasing its maneavurability for urban work seems to be precisely where this rifle excels. Even if the military chooses not to adopt this weapon, the units (primarily special forces) where soldiers are permitted to pick their individual weapons may still opt for one of these firearms.
