A spokesman for the international charity Peace One Day confirmed the gun that caused armed officers to storm the Primrose Hill home of the actor Aaron Taylor-Johnson and his artist wife Sam would be auctioned at Bonhams in October.
The M16 art project is an incredible way to raise awareness of the campaign that we are presently running in the Great Lakes Region of Africa.
I am delighted to be working with Sam Taylor-Johnson again.
She is a huge supporter of our work, and I can't wait to see her finished piece
A similar project two years ago, when Taylor-Johnson refashioned an AK47, made £10,000 at auction.
Other artists taking part in this year's project include Jeremy Deller, the Chapman Brothers and Peter Doig
