I've had my Umarex Airsaber for over a year. In that time I have fired a lot of arrows though it to 120 yards at my home range. My best friend also bought a identical airsaber and identical UTG 130 BDX scope. Having set both up and shot both to 120 yards. Identical accuracy. The Umarex arrows suck....I only use Aluminum Easton 2219 xx75 22 inch crossbow arrows,,,,just remove knock... I have a external regulator and with the Airsaber I get best velocity all 3400 psi...474 grain Easton 2219 with 100 grain point at 405 fps...Umarex arrows fail and need sorting. Easton much better quality and cheaper too. I bought last ones on EBay for $.29.75 a half dozen if you buy 3.. Not bad... My Airsaber was $230.00 on clearance as midway. It has been very easy to shoot good groups to 120 yards consistently with Airsaber, Easton2219,,UTG 130BDX combo... If your state allows this is a stupid easy accurate safe setup...Airsaber will shoot with any crossbow made regardless of price. It has been a cheap easy process shooting the Airsaber and UTG combo accurately... Its cheaper and works way better than it should Airsaber and UTG Combo
