A non-standard alternative to the standard issue M41A-MK2 available to the jarheads of the USCM. The L42A is known for its higher lethality, due primarily to the significant increase in barrel length over the M41A. It can quickly change barrel attachments because it features a larger muzzle ring quick detach than the M41A. The increased barrel length increases muzzle velocity which leads to significantly better ballistic coefficients, drastically increasing the accuracy of the weapon. The L42 holds significantly less ammunition in each magazines, only 25 rounds in a standard magazine.
