The guns which I recorded in August 2010 already are finally ready and release on www.boomlibrary.com. I recorded in the US, Oregon. 17 weapons were recorded, using 12 microphones in 96kHz, 24-bit. I recorded onto a Sound Devices 788T and a 744T, synched using Sound Devices built in C-Link technology.
And the following is a demo for what is possible to create with one single shot of one weapon from the Construction Kit:
