    Noise and scraping

    Posted by Jim wheeler on Dec 28th 2022

    The bow squeaks when you draw and it's scraping the finish off the rail I'm afraid it will wear the cable out fairly fast. Other than that it does shoot nice

    Excellent crossbow

    Posted by Bryan Rummel on Dec 27th 2022

    The killer instinct crossbow is easy to assemble. Once assembled it is fairly easy to sight in. I used a bore sight laying in the rail to get the scope close, the fine tuned it from there. I harvested a nice 10 point

    great crossbow at a reasonable price

    Posted by Joseph McCollough on Dec 27th 2022

    I purchased my Fierce 405 a little over 3 years ago at Walmart and have harvested bucks and does every year with it. I do all my hunting from a blind with shoot through screens. I use 442g bolts with 100g fixed broadheads and get good pass throughs every time. Where I hunt is pretty brushy, so I don't take shots over about 30 yards. I di have a slight problem last year with the laminate starting to peel off the limbs. One call to tech support got them replaced and I had successful harvests again this year with the new limbs.
