Things I liked: This seal is better than the original
Things I would have changed: nothing
What others should know: If you are considering this, then most likely you already have the gun apart... you might as well do a good tune on it at this point. Plenty of vids on You-Tube explaining the procedure. The gun will last and work much better if you just take the time to do it.
Things I liked: Works perfect
Things I would have changed: Nothing
What others should know: perfect snug fit. Install into tube very carefully, take your time as you slide it past any openings

Things I liked: Fit to piston and compression tube were perfect. Noticeably better shot cycle and power is back where it should be.
What others should know: This seal as of 12/2016 is red- it's the correct seal just not white as pictured. As others have stated de-burr & clean the compression tube before installing. Lightly lube the internal(piston side) before placing on piston, then a light smear on the outer side surface taking care not to get any on the front of seal. Very carefully guide piston past punched holes in tube to avoid nicking the seal. That's it as far as replacing the seal.
