Vortex Optics Impact 4000 Ballistic Rail-Mounted Laser Rangefinder

Absolutely amazing. Easy to set up. Pairs with geobalists. Makes adjusting to different ranges fast and easy!

Kind of a chore to set up and configure, but if youre willing to invest 30-60 minutes setting it up its a game changer. Provides me with very good firing solutions with custom velocities and bullet ballistics. Definitely worth it if you shoot long range

This item came in an open box and was advertised as new. The remote was not connecting properly and signal was being interpreted. Condition was not new but it was used if you see the mount, you will see. Please advertise products properly and request immediate refund.

This LRF is awesome. Lots of options but basic ranging is easy. Looks kinda ‘tacticool’ if you’re into that, and it looks large on the side of my 6CM AR-10s hanguard, but doesn’t interfere with my shooting rest. Haven’t had a chance to range more than 150 yds but is very repeatable at those distances. Overall a great item, just a bit pricey.

Easy to calibrate, mount, and zero. It's an all-in-one ballistic solver and range finder. Good data in will put out good data. Used it up to 1200 yards on a UKD range and was able to score hits on every target as long as i had a stable firing position. Use with Geo Ballistics app on your phone (it automatically unlocks premium version when you connect your Impact 4000 the first time) or use it standalone and get the same amount of features. Only complaint is that it's not QD since you have to recalibrate if you take it more than 30 miles from where it was calibrated last. If you want full use of the solver. If you're just using for range (Idk why you would), then you don't have to worry about it.

This thing straight up works! A little tricky to calibrate at times but worth it once you get it set.

Anytime you move more than a set number of miles, or change altitude, you have to remove it from your rifle and perform an absurd chicken dance to calibrate it. The calibration fails 9 times out of 10 and just when you are ready to smash it (but you remember what this POS cost you) it finally calibrates. But wait, it gets worse. When you remove it from your rifle, you have to rezero it. Re-zeroing requires having the laser zeroing target at 50-100 yards. Not at all convenient in the field for an actual tactical engagement.

The product matches the description. Good quality product. I recommend for purchase. The seller sent the goods quite quickly. The parcel track was tracked all the time. It's very convenient to shop through Amazon.com
