I love this crossbow! Balanced, lightweight and shoots incredibly well. Loud drawing the string but overall an impressive piece of hunting hardware. Thank you Killer Instinct!

Excellent hunting xbow. Shooting 445 grain high end full capture bolts into 1" @ 60 yds. Seed ring @412. At 70 yds, and beyond, I have to crank the ring to 430. The big bolts aren't slowing down. Ethical 45 yd shots on game go down so fast, they don't have time to move at the report of the shot. Great balance. Trigger stiff, but NO creep. Rope cocker stinks, but then, don't they all. Nice, Wide, steady pointing bow, without pinching the string serving to pieces. I can elaborate on that one. The 425 is solid with everything I need in a whompum hitting archery weapon. Hope you guys keep em coming long enough to get the masses involved. BTW, all pictures depict this thing being rather large...it's not. Shoot the heaviest bolt you can find, and have a good target. Excellent Value and performance . The accuracy I got was off a pair of Shooting sticks and my folding stool. Something I can duplicate on the edge of a bean field. Great piece KI, Thank you.

I made my order Speed 425 august 30, I receive my crossbow September the 8 and I live in Canada, St Hubert Québec. I have practiced twice and I take bolt 532 gr. Killer instinct do a error name that's not a speed 425 crossbow that's a formula 1 crossbow. Thank you KI for your speed service and your Formula 1 Crossbow.

The killer instinct 425 speed crossbow is by far the smoothest and best shooting crossbow Ive shot. It outshoots my tenpoint very easy. faster, smoother, stronger. It shoots lazers! great bow!!!!

425 speed
Written by Aaron dew on Aug 6th 2020

The 425 speed has some major power behind it. I first started at 20 yards and well first shot went through my 14 inch thick heavy duty target. luckily a 4x4 stoped it. I'm glad I bought extra bolts as I lost one at 50 yard that is still in the middle of my 30x36 in Styrofoam target. It had practice arrowheads on it. It has a lot of power great scope. But just my opinion if you are thinking of buying a cheaper crossbow and buying a better scope. Save some money and buy this crossbow you wont regret it.

Fast....Accurate ...well made....very happy with it! Scope is good,easy to sight in! Scope Caps are CHEAP both broke at hinge just by opening them normal within 1st hour. No ...I wasn't rough with them.....4 stars only for that reason!
