@ Mengkom... Related to the sniper rifle... Can we upgrade the range of fire... Or make it more silence, without using the silencer... Can the shell penetrate the armor of an ifv armor or at least an apc armor.... I was hoping it have enough power to penetrate through a mbt armor...
do you mean tweaking the existing rifle?
Simple answer: NO
a lot of compromise have to be made
you want longer range?
-lengthen the barrel, but it will make the rifle unwieldy
-increase the propellant pressure, and you make the barrel wear faster
-with current caliber, the bullet will drop significantly in longer range, and aerodynamic of the projectile won't compensate enough for wind drifting, so it is pretty much useless anyway
you want lesser sound signature?
-you can make suppressor being integral to barrel like MP-5 but it will bleed the pressure and reduce the kinetic energy of the projectile
-you can use subsonic ammo (complementary to supressor), but it will significantly lower the range
if you want a sniper rifle with longer range,
you need to adopt a new long-range specific caliber like .338 lapua magnum
basically develop a new platform, with new standard and new logistical support system
if you want lesser sound signature then attaching supressor is the most viable option

the existing 12.7mm anti-material rifle is able to penetrate certain angle of APC/IFV
but you want shoulder mounted sniper rifle to penetrate MBT ?? now that's just wet dream
too problematic from technical standpoint
just shoot 30mm bullet from A-10's gatling gun and it's done for
