Is Mexico's new FX-05 one of the best assault rifles?
It certainly is. Its design is so advanced, that representatives
from Heckler and Koch (German weapons manufacturer) accused the
Mexican manufacturer of patent infringement on the H&K G36
assault rifle. Upon closer inspection, they found out both rifles
have similar designs and exterior appearance, but instead have a
completely different internal mechanism.
It is however noted that the similarities were not accidental,
as the FX-05 uses the same ammunition (5.56x45mm NATO rifle
cartridge) the G36 uses. However, the FX-05 can be retrofitted to
use a 6.8mm Remington SPC cartridge, while the G36 cannot.
It should be noted that the design has yet to be put to any sort
of test as to prove whether or not it ranks among the best assault
rifles. While there's certainly potential - given that the rifle
itself presents nothing new, but capitalises on features of
previously proven designs - the short service life and limited
conditions in which the rifle has or will see use (unless an export
market opens up for it) makes judging it comparatively to other
rifles a bit difficult to do with any basis or accuracy. "Best"
itself is a completely subjective term, anyhow - what's ideal for
one application may not be for a different application.
