The position of the pistol grip and firing control group has been redesigned to make the 240LWS even shorter than the 240LW. With this, Barrett moved the entire grip forward by about four inches, to where the front of the trigger guard is at a right angle to the ejection port. By moving the fire control group forward, the overall length can be shortened because the machine gunner no longer needs a traditionally longer stock to compensate for the original position of the pistol group, towards the very rear portion of the receiver. Instead of the operator using a cheek weld on the stock, the operator can now rest his face against the actual receiver of the machine gun, it also allows the operator to have a closer fit of the weapon. But by doing this, the bolt had to be modified accordingly, because the original location of the sear is no longer there. Barrett had to move the position of the sear catch on the bolt to further down the length of it. The bolt group is still the same as the original M240 design, with the exception of the position of the sear catch. Though moving the grip forward took away the ability to connect the LWS to the standard pintle adapter from the M192, Barrett made available as part of the system a new adjustable pintle adapter that works with both made by Military Systems Group. As of July 2017, it is not yet clear if that adapter is compatible with the M192 or M122 Traverse and Elevation (T&E) mechanism. However, the primary intended use of the LWS is not to be mounted, but instead being a part of a small man team that needs the additional firepower while on a foot patrol.
