Montneel’s Z1 was a very popular paintball marker in the early nineties. But because of various reasons, a number of clones were also produced. Akraturn had been the original supplier of Z1 bodies to Montneel so it was not surprising that they would produce a clone of their own.
Sold under the Avenger name the AK-1 was a high quality product unlike some of the cheaper knock offs. I saw the AK-1 at 1994 NPPL World Cup in Florida and I was very impressed with it. I picked up this flyer at the event and it gives a good overview of the Avenger AK-1.
