Hi Guys,
I'm not the seller or the guy who put these kits together, but I can answer your questions, since I am the guy who did a good bit of the testing on silencing these crossbows.
The short answer is No! The kits have not been modified or changed and the member who was originally selling them has long since sold his PSE crossbow and moved on to another brand
What we did learn was that these materials seemed to work well on certain trigger trigger types, but not on others. I shoot and use these materials on my TAC15i, but on a "Timney" trigger, so I know these work when applied correctly. I can't speak for any other brand of trigger because I can only test what I own and can't comment on those I don't.
It is important that if you should decide to quiet down your crossbow that you make sure that you use a longer piece of material to cover as much of your hammers surface as possible. This means over and around the top of your hammer as well as the length of the striking surface. This nor only provides a better bonding surface, but also insures that you are applying an even amount of build up to all surfaces where a contact with other part can occur.
The company 3M Scotch makes an Outdoor Double Sided Mounting Tape that is sold in 60" x 1" rolls. It has a 5lb. holding strength. This is the adhesive base that is used for the silencing material. It sells for about 5.00 per roll and can be found in some hardware stores.
Next, this is covered with a thin rubberized surface material which is typically used as either rubber pistol grip side plates or also used as the rubberized material for foot plates on wheel chairs.
Personally, I use the pistol grip material which I purchase from Brownells.com. Two grips will produce dozens of strips, if cut with a pair of sharp scissors. The grips sell for about $10. per pair. They are just a very thin rubberized material that is need to protect the foam tape from the hammer contacting the frame pin on each shot. It's the foam tape that absorbs and silences the impacts.
I have about 500 or more shots on the one that I applied and it hasn't moved or worn since I applied it.
