I had to send in my Texan 50 cal tx2 ,valve in for warranty work. The safety quit working. I did add one talon tunes trigger spring. That's it. So after shooting well over 1000 rounds through my new Texan lead accumulated inside the trigger mechanism and screwed up things. I had to clean my rifle with a regular nylon coated rod.and lead remover. My barrel was leaded. Airforce won't honor the warranty because I added a talon tunes spring . The bill is $430.00. I thought a a few minor parts no big deal. Things wear out get dirty need cleaned ect. I'm used to that. $430 to make a safety work and clean the trigger group is alot of money. $430 can buy you a new cheap deer rifle. I thought Airforce was the most basic and easy to work on air rifle design. I understand from the volume of shooting lead accumulated inside and caused problems. If I would of known the outcome I would of.never sent it black. I don't like the trigger anyway. Im complaining I wish things were more similar to the air.gun.and firearms world. Who.would.ever worry putting about Jewell trigger in a rem 700 or a Krieger barrel.or a MC Milan stock. They market the Texan like a customizable platform. Yet you can't make no improvements. $430one talon tunes spring to improve the trigger. Yes I actually shot my Texan 50 cal at least 1000 rounds all sized to .510 cal pure 100% roofing soft lead and lubricated or powder coated. So for a 1000 round reviews. My 50 Texan needs $430 to make it shoot again.
