Sigma Precision, Chatsworth, California
Sigma Precision was/is a machine shop located in Chatsworth California that was run by Randy Christophe. In the early to mid 1980s, Randy's cousins, Tony and Ron Verbeek began paintballing and later joined the Southern California team Sudden Death. Tony Verbeek worked for Randy and Ron was an engineer who would occasionally work on projects at Sigma. Randy is credited as designing the first nelson barrel with a screw together breech which would be fixed in position by anodizing. Sigma manufactured Nelson bodies for Line SI, AGS and likely Lapco. Sigma also produced the VerbeekOlater, which was used by Sudden Death in the 1988 National Survival Game Championships. It is my believe that Sigma may have also made barrels for Unique Paintguns Hornet, possibly for Termite Smith, and possibly for Steven Buzick at Rebline.
