The Mk-54 is heavily based on the Hekler and Koch HK-417.
It fires a 7.62x51mm NATO round and features a clear magazine to see how many cartridges you have left in your magazine. There is a fore grip and laser on the bottom rails to assist with aiming. The stock is adjustable and taken from a SCAR weapon system. Iron sights are included and the ACOG sight is a 4x32 magnification.
