The PPF XM18 is an advanced assault rifle designed to replace the M16.
The XM18R, fitted with an S&B Short Dot.
Overview
The Phoenix Precision Firearms XM18 is, in essence, an updated version of the SCR rifle. Present among those changes are an ambidextrous charging handle, detachable forend, new stock (both solid and folding), an advanced muzzle brake and 2 new calibers. In contrast to the SCR, a heavy battle rifle made primarily out of metals, the XM18 is a light ASSAULT rifle composed of polymer and carbon fibre, with only the firing mechanism, gas system and barrel being made of metal. Speaking of the gas system, this rifle has 2 options - Direct Impingement or short-stroke piston.
Variants
XM18R
The "R" is for "Rifle". This Variant of the weapon, shown above, is meant for marksmen and infantry soldiers. While long, the rifle more than makes up for its size with its devastating power and accuracy, while its solid spring-loaded stock absorbs most of the recoil. Like all other XM18s, this one has a muzzle brake that pushes forward and down to neutralize muzzle rise.
XM18C/CS
The carbine rifle is equipped with a shorter barrel and folding+telescoping stock, with half the railed forend removed. It has a short buffer tube built into the back of the receiver, as opposed to the Rifle version's long one, nevertheless, the R can still be converted into the C in just a couple of minutes. The carbine also comes in an integrally suppressed variation that fires subsonic .378 Silent Phoenix/.300 BLK rounds.
Such a lust for carbines? WHOOOOOO!?
XM18P/PS
The P version is light and concealable. I said so, and you dare not say otherwise! In all seriousness, though, the P was created with the same concept in mind as the MP5k: a vertical (reverse-angled in this case) foregrip, no stock, short barrel and a faster firing speed due to a short gas system. This beautiful piece can also be suppressed. If you're man enough, you can even dual-wield it... What's not to like?
Arnold approves.
Ammunition
There are 2 unique cartridges for the XM18: The supersonic 6.6x44mm ".26 Phoenix" and the subsonic 9.5x38mm ".378 Silent Phoenix". The former is very similar to the 6.8 SPC, but features a higher maximum chamber pressure, while the latter is the same thing necked up to take giant slow bullets. The rifle is also chambered in 6.8 SPC, 5.56 NATO, and .300 BLK.
