A weapon concept base off the TAR-21 rifle. It has a bull barrel 30" in length. With the bull barrel, the weapon is around 25" long. It is a bulpup sniper rifle that fires a 5.56x60 bullet. The standard magazine holds 20 rounds, with optional 30 round magazines buyable. It has an ajustable scope that ranges from 6x-12x allowing for long range shooting. It has both semi-automatic and automatic firing modes to serve as both an ausalt rifle and a sniper rifle, while beign the same length as an smg.
would be cool but it still wouldnt be ovrely accurate at 1000yards + because batterl is so short, i know its bullpup aswell so it would be good urban sniper, likes streets of baghdad, and as for the bullpup design, you got to be careful there the recoil would quite literally dislocate your arm if you used something like a 308 in it, with the barrel being so close to the arm more shock is absorbed by your arm when you fire it.
Google the Keltec RFB, which has a shorter barrel and more recoil than this would have, which makes it seem "Slightly" bearable.
a 30" barrel is longer than the M40a3's barrel...
