I have an unregulated USFT built in 2011. The valve periodically leaks. Tim and I have shaved the poppet but leaks periodically return. Also, I broke the stem at one point and the SS rods I typically use seem to bend after a while, causing changes in muzzle velocity and leaks.
Tim doesn't have any replacement poppet/stem parts right now. So am hoping another USFT owner might have extras. I can live with either the .280" or .285" diameter poppet. An extra spring would be nice but not essential.
Regards.
