I made a visit to Kel Tec yesterday, to have my Gen 2 Sub gone over and "upgraded" with a new style front sight. I met with Nick (Customer Service Tech) and Greg (Sub 2000 Repair Tech) and Greg asked some questions about how I liked my sub and he took my sub in for a look see. They wound up doing a lot more than what I figured they'd do. Really gave it a tune up. Took about 2 hours. Pics to follow. First is the Repair Work Order, stating what was done...but some work was done that wasn't on the sheet, just told to me after.
