About JF Paintball & Airsoft JF Paintball has been in the same location at 1253 E. Main St in Grass Valley Ca since the year 2000. Jeff Roberts took over JF Paintball on September 9, 2004 with one thing in mind Provide friendly professional service and a great selection of products for everyone from the 1st time player to the seasoned veteran. Being a paintball player myself I understand the need for a shop that I can not only find all the parts, upgrades, and supplies I need to play, but also friendly factory trained staff that's there to help me with what I m looking for and not trying to sell me on their style of play. The first thing Jeff did along with long time JF employee John Jensen was clean, paint, and remodel the store to make it more user friendly, and make room for all the new products they filled the shelves with. After the store was in shape and the name changed to reflect the expanded selection of Airsoft products they began to work on themselves. Starting with 5 days of training at Paintball Technology Institute ( PTI ) and continuing with factory training they soon became the factory certified service center for most paintball markers available today. John has also become an expert in Airsoft sales, service, and upgrades. "We are commited to help you choose the proper gear for your style of play not our's, and we have the factory certified training to keep it working when you need it. We continue to expand our knowledge thru factory training, and attending the major trade shows to keep up to date on all the new products."
