ExcaliburS5 String Suppressor | Archery Hunting Durable Effective Versatile Vibration & Noise Reduction Crossbow Silencer

...it's too bad these weren't included with the crossbow...then again Excalibur charged me for wax, a string changing string, and the comb riser for the stock on my Ibex (yes, after all these years it's still kicking you know what and taking names). It's just how they do business. And in no way am I putting down their products, as far as I'm concerned they are the best on the market for my uses...I just don't like the hidden costs of add-ons.Quality wise I cannot complain and they do help. I can't say how many decibel attenuation you'll hear but you'll notice it is quieter.Beaver strips in the string are also helpful.

Best deal I found so far for these stops. If you own an Excalibur crossbow I recommend them if just for the shot shock and vibration. 50/50 on noise suppression but no doubt that they greatly reduce string oscillation and vibration dramatically.Bear in mind this also reduces the shock going to the limb tips especially if you shoot a Flemish string and a 350gr or minimum weight arrow.Lots of energy being absorbed by these things when the string hits them.Legit machined construction so they will last forever. The rubber stops seem very durable and I doubt they will need replacing very often.Do not set your bow up with these right against your string at rest. They will be torn up very quickly if you do. Excalibur website forum is a great place to learn about your best set up options.

The quality of construction is good which is why I gave two stars but there is no noticeable reduction in sound I can detect. Both my father and I have Excalibur Axiom and I recently purchased the S5 suppressors to try on mine. After a day of side-by-side comparison neither of us could notice any difference in the sound. There was perhaps (I might be reaching) a reduction in after shot vibration but not in sound that we could detect. We tried setting the string to different heights off the pads to touching the pads and never got a noticeable decrease in sound. To do over again I would not spend the money or add the weight. I have just finished removing them as there is no benefit I can discern so the added weight is just added weight.

They helped the bow a little, But nothing major. Looks better with them and glad I bought them. Don't expect huge difference in the reduction.

This product works as advertised. It is not as good at quieting string noise as I thought it would be. It does reduce the strkng noise which is an improvement over the stock crossbow without them inztalled. A bit expsensive for what you get but Excaliber has a captive audience once you have purchased their product and need accessories.

THIS IS NOT DESIGNED FOR THE MATRIX LINE!!!Although the box says something like "all Excalibur crossbows" it only works on the older models. Excalibur really needs to put stickers on the package stating this! Kinda sad when you have to find a forum to get the proper accessory.If you have a MATRIX you need the REDS string supression system

In my opinion, I don't think it justifies the price you pay. It doesn't really damper the noise at all and, as far as the vibration concerns, I haven't noted much of a reduction either. I have mine on an Ibex and I haven't noticed any difference. As a matter of fact, the other day I noticed that my arrows were all of the sudden hitting over three inches high so, after checking the distance, the scope setting and anything that could have been affecting the arrow trajectory, I decided to re-sight the weapon . Well, last night while replacing the factory string on the Ibex with a Flemish one, I discovered that the rubber pieces were cut in right to the metal supports ends due to string impacts. So, my theory is that these things were actually decreasing the speed of the arrow by restraining the complete free forward motion of the string. And that explains why, after the rubber pieces were destroyed, the arrows were hitting about 3 inches high as nothing was stoping the string for completing its normal forward-backward cycle during the shot.UPDATE: After replacing the string with the Flemish one I set the distance between rubber pieces and the string at 4.13 mm and took 12 shots with the suppressors on; the distance did NOT change. Then I removed the suppressors and took another 12 shots; there was NO DIFFERENCE in the point of impact so, IT DOESN'T affect the velocity as I initially thought. However, when I put the suppressors back, the string was pressing hard against the rubber pieces so, it DOES HELP keeping the string from stretching. Still, there was NO DIFFERENCE in noise suppression and very little in vibration. I hope that, by keeping the separation between the suppressor and the string at ONE time the thickness of the string (4.13 mm),will help keeping the rubber pieces from being severed by the string.All that been said, I would advertise this item as "string saver" rather than "noise suppressor"UPDATE: I just installed the Excalibur dissipator bars; now I really noted a decrease in noise and vibration so, if you want to quiet down your crossbow use the combination, it works!

$35 for about 1% noise reduction? Perhaps it helps protect the string and reduces vibration in your hands, but it does nothing for the sound in my opinion.(Edit)So I finally broke out my flemmish string and between the new string and the dampeners, it's definitely quieter. Perhaps the original string was set too far back/forward for the dampeners to do their job, or maybe the flemmish string is just that much queiter. Who knows?
