Killer Instinct is one of the companies that manufactures crossbows overseas and are well known for limb problems.
Several crossbows from over there have limb problems from splintering to actual breaking. My thought which I have
mentioned in a few posts:
1)the limbs are removed too soon from the mold and are not properly cured and or a poor quality material is used.
2)the newer crossbows with higher draw weight and narrower designs which are gaining popularity are putting a lot
of stress on the limbs, bowstring and cables regardless of what brand.
If either company selling these crossbows run out, it takes up to a month to import unless they are flown which costs
a lot more. The more crossbows these companies can import and are willing to take a chance on selling, the cheaper
they can purchase them for and there fore the cheaper they can be sold. It does not pay some of these importers to
stock parts for the price they can buy the whole crossbow for.
Here is an example: I have some of the rebranded Rocky Mountain 405 and 415 series crossbows that have limb
failures which I realize now is common. Some of these same crossbows can be purchased under a different name,
depending what business wishes to sell them. A few add on's to show the difference but many parts are interchangeable.
Pricing a complete riser for a 415 lists as approximately $120 U.S. To purchase 4 limbs for the same crossbow from
this same importer is $117 U.S. For me, I purchased the complete riser even though I only required the limbs. A cable
and bowstring set from another U.S. company for that riser is $109 U.S. Purchasing the complete riser, I am getting
the bowstring, cables, axles, spacers and cams for $3 more than the price of just the limbs.
For a few dollars more, if one is thinking on purchasing the Center Point Sniper crossbow, I would purchase the
XT390 as it is the newer version, a better trigger system that if it needed a modification, just requires a lighter coil
spring that is very easy to change out.
I have three of these crossbows. The first has absolutely no hard trigger pull or creep. Doing a trigger pull test after
reading reviews on some of the Center Point 370 Sniper series and posting them, several responses were my gage
had to be faulty. Before purchasing the Lyman digital gage I read feed back comparisons on the digital and the hand
pull spring loaded gage. First off, digital is more accurate and multiple readings can be taken and recorded on the gage.
Maybe I got lucky so I purchased a second XT390. This trigger was very hard to pull and had the trigger creep. I disassembled
the trigger system and swapped the coil spring. Back to an easy trigger pull with no trigger creep. Who ever assembled the
trigger box installed the wrong spring. The length of the spring, inside and out side diameter are the same. The difference is
in the diameter of the wire to make the coil. A smaller diameter wire is weaker, there by reducing the effort to compress the spring.
This crossbow came back on sale so I purchased another basically due to having a spare set of bowstring and cables. Again,
no hard pull and no trigger creep.
All three crossbows were purchased from the same company this year, just a few months apart.
Note: with the second crossbow before changing the spring, my finger told me it was a hard pull with the trigger creep.
I compared other brands and series of crossbows I have that had no hard pull or trigger creep and the readings were
very comparable to what the Sniper XT390 showed with no hard pull or trigger creep using the Lyman Digital trigger pull
tester.
In regards to the life time warranty on the Killer Instinct, what good is it if they keep replacing the parts with the same faulty
parts unless they make a correction in their manufacturing process.
Wishing you all the best.
Take care.
