I've decided to use Krytox GPL-205 to lube tune my springers. Zoro.com sells a 2 ounce tube for $41 which is the best price I've found. Do people here favor Krytox over traditional moly grease and spring tar? From what I've read, Krytox should be applied very sparingly anywhere that moly...

I replaced the gauge with a Crosman pressure gauge, and now it's no longer leaking. 

I replaced all the O-rings with HBNR 70D O-rings from The O-ring Store and installed a new poppet and TP seals. I got the poppet and TP seals from Crosman. I greased all the O-rings with O-ring grease but did not apply any grease on the tube threads. I wrapped the gauge threads with plumber's...

Thanks for the help. My electric handheld drill has a bubble level on the back which helped greatly in keeping the drill straight. I only eyeballed the level of the TP when it was in the vise, but the perimeter of the hole came out surprisingly even on both sides even with this crude setup.

People recommend #113 70D HNBR O-rings for the 1720T and Prod, but the Crosman parts list shows #113 80D HNBR O-rings. So should I buy #113 70D HNBR O-rings? Should I buy all the other O-rings directly from Crosman? It looks like the minimum quantity to purchase from theoringstore and...

Is the poppet named "Striker" and part number 1763A036 in the Crosman parts list? 

Air is leaking from around the gauge on my Crosman 1720T pistol. I removed the gauge and replaced the Teflon tape on the gauge threads with one 1/4" strip 6" long which reduced the leak a lot, but it still leaks. I tried two 1/4" strips at first, but that was too much tape. So the next step...
