ExcaliburGuardian Archery Hunting Durable Lightweight Aluminum Versatile Crossbow Anti-Dry-Fire Scope Mount

Added to my Matrix 355. Easy to install and functions perfect.

This is a needed device if teaching young ones to handle crossbow. Cuts out the ooops and sorrys, had my son and youngest nephew on range and nephew got a big kick out of the sound from dry firing. Twice, plus launching a luminok over the target backstop.He’s done forever.Great upgrade, easy to install.

4 stars for two reason, the first one I got crapped out and was stuck. nothing I did would fix it.sent it back and the second is holding up fine.the second one while doing just fine has changed my point of aim with the factory bolts from 20 to 25 and that Is with it dialed down as far as I can get it to go. not a huge deal but im still spot on for 25 35 havnt shot it at 45 yet. but at those two ranges I am golden.so with those two minor issues I knocked off a star. still an awesome addition. but it should be standard on all their xbows if you ask me.

As advertised, this device was shipped in a timely fashion, arrived as indicated, had excellent installation instructions and works on my Excalibur Crossbow as advertised. It functioned perfectly when I inadvertently pulled the trigger without a bolt loaded.Very satisfied.

perfectly fit

This was a GREAT upgrade to my Excalibur Phoenix. it was super easy to install, and i like how it is much longer than the stock rail and arrow holder too. it not only gives dry fire protection, it also holds the arrow more securely to the rail.

Easy to install with no loss of accuracy. A must have if you are carrying your crossbow through the woods with it cocked. It doesn't actually prevent the trigger from being pulled, but catches the string 1" in front of the release. While hunting you need to check that the trigger hasn't been pulled. If it has, you must re cock the bow, but it is worth the extra effort to prevent a dry fire.

I have replaced a few of these spring design is weak ,unit lever you push in to uncock crossbow is sloppy side to side, I have 6 Excalibur crossbows the early Anti Dry fires were the best I have never had a problem with them ,and bows are shot daily , and there expensive and you have to take crossbow apart after you have it shooting perfectly and the reinstall new one and re sight your bow again big pain in the ass.
