A high quality upgrade to the factory string for the Excalibur Matrix Series crossbow.
Custom-made for us by JBK Bow Strings, this direct replacement string has almost NO stretch, so you don’t have to waste time shooting-in your string and re-adjusting your brace height.
We gained 5fps on our test bed 355 Matrix over the stock string.
28 strands of BCY Mercury 2 string material pretensioned at very high poundage to help avoid creepand .036 Angel Majesty serving makes this one of the best endless loop strings you can buy!
