Updated Muzzle lock for Kriss Vector Kit by Ict890

So If you are printing Ict890's Kriss vector mod kit and found a problem with the muzzle lock not working I was able to do a quick fix, I was lazy and did this project in Tinkercad so the end bit is a bit off in terms of size, this just means that you need to put some glue in the little hole so that it holds properly
