In regards to crossbow warranty or for any other item, to obtain warranty, the
faulty parts are replaced with the same unless a company does an upgrade.
This is where the earlier Barnett crossbows failed. As examples: 1)Carbonite
riser did not like the cocking and shooting where it would start to crack from
the inside, working out and explode doing damage to other crossbow parts.
Plating and filling in the two large holes with JB Weld corrected this problem.
This was a personal modification. Many thousands of shots later there has been
no failures.
Newer model crossbows, this area had a gusset, plus the riser was narrowed
in width which made for a stronger riser.
2)poorly constructed cables where one part looped through the other to make
a cable. This made for a weak link that would stretch.
3)A Teflon strip placed where the cables fit in the "J" section of the rail-stock.
This was not a flat surface and not enough sticky on the Teflon strip. This allowed
the Teflon strip to wrinkle.
4)as with many crossbows, using cable slides. Cable slides are known for chewing
up the cables. Cable slides also cause additional friction when cocking and shooting
the crossbow. Eliminating this and serving the cables in that area with BCY .030
serving greatly increases cable life. One may gain a few feet per second with this
modification.
5)Barnett trigger box where one spring returns the latch to a partial up right position
after the shot. The second spring returns the latch to the upright position after the bow
string passes over when cocking the crossbow. These torsion springs were too brittle
and stiff which could fail at any time.
Going to a torsion spring with less resistance corrected this problem. This was another
personal modification.
Wishing you all the best.
Take care.
