I purchased the HCA 13617 model for my new Invader X4. Foot stirrup, bolt tension ,and limb dampeners fit fine. No issues with them coming off limbs as of yet. As other reviews posted, only 2 of the barrel dampeners will fit for sure as the cable saver will barely touch them with 2 in. I installed with the groove side up first and it seems like that is how there made to install, but they were not snug and slid in the channel this way. The spacers were to much and I couldnt use those at all. I ended up disassembling again and installed the barrel dampeners with the flat side up and they fit more snug and dont appear to slide in the cable saver channel now. Definitely seem to take at least some of the noise off, but seems smoother now, probably by reducing vibrations. Its still a crossbow and can only be suppressed so much. If you want stealth quiet, maybe switch to a blow gun.
Made absolutely no difference at all on my Invader X4. 92 decibels without the dampeners and 92 decibels with the dampeners. Unfortunately the one accessory that may actually reduce the noise (string dampeners) isn’t compatible with the X4.
The barrel dampeners are not compatible with the Invader X4. Here's more detail. There are four barrel dampeners provided with this kit. They are designed to fit snug between the cable saver and the end of the barrel that butts up to the Vibra-Cush portion of the bow assembly. In the Q&A section of this site, company reps are saying three of the four will fit. This is not true. It's physically impossible. The maximum number of barrel dampeners that the Invader X4 can accept is two. However, when two are installed there is at least an 1/8" of play. In other words, three to too much and two is too little. I'm puzzled that the company doesn't appear to know there's a compatibility issue with the Invader X4. Have they even tried to install the barrel dampeners? Or just assuming. I give this product 1 star for that fact alone. Although the Invader X4 is my first crossbow, I've been bowhunting with compound bows for over 4 decades. So I know my way around archery technology and offer this review with considerable experience.
I purchased this kit for my Shadow Ultra-Lite because it seemed a little on the noisy side....Before I installed this ,I shot my crossbow a few times while using a decibel meter...Then with the dampening package...It worked ,lowered it by 5 decibels.. Not a lot but better. Well worth the money....Thanks TenPoint !!
The Tenpoint sound deadening kit reduced the noise of my crossbow significantly. Is it as quiet as a vertical bow? Of course not, but it is quiet enough that if I miss I can get a 2nd shot because the deer can't figure out where the sound came from.
The crossbow has such a violent reaction that some sound is inevitable, however by using the dampening methods Ten Point has available you can cut that sound down to the point of on a windy day they may not hear it at all. On a perfectly still morning or evening they will hear a crossbow no matter what you do. Whether or not they have enough time to react (duck the string is doubtful with the speed of these bows today.
I purchased this noise dampening set for my first TenPoint crossbow, the Turbo XLT. It does an excellent job of quieting down that crossbow. The only issue I've had with it is that the limb dampeners tend to work their way apart and towards one end or the other of the limbs. Also, the small dampener that slides over the arrow retention spring can come off too easily when target shooting or removing an arrow by hand. Mine did this a few times until it was lost forever after not noticing it coming off the last time.
