A couple of XM3 clones.
The XM3 was developed by DARPA in 2005 to solve some of the shortcomings of the M40A3 that was in service with the Marine Corp.
The XM3 is lighter, introduces a night vision dedicated rail and a muzzle device compatible with a suppressor. 52 rifles were made in this configuration and they had a short live in service, despite being well received by the end users, there was no support structure around the gun, there was no training or maintenance programs for a gun that sported a different reticule configuration than other rifles already in service, like the MK13.
After 2006, the guns were transferred stateside to a logistics base of the USMC, scheduled for a destruction that thankfully never took place, and ultimately ended up in possession of the US Army, that auctioned them through the CMP to civilians.
