LMBR R2A Ballistic Shooting Chronograph for Airguns (with D-SUB9 Connection)
Level up your shooting game with the LMBR R2A, the gold standard in ballistic precision. Whether you’re a serious airgunner or a firearms enthusiast, the R2A offers professional grade accuracy in a rugged, all metal package that’s built to last. Unlike finicky radar units or light dependent sensors, the R2A’s open sided design makes it incredibly easy to shoot through and versatile enough for both indoor and outdoor ranges.
With the ability to calculate velocity, kinetic energy, and shot statistics in both metric and imperial units, you’ll have all the data you need to fine tune your consistency and stay within legal power limits. It’s portable, runs on standard AA batteries, and even features a 250 shot memory with PC connectivity. If you’re looking for a dependable, "buy it once" tool to perfect your setup, the LMBR R2A is the only chronograph you’ll ever need.
The LMBR range has quickly become a firm favorite here at Optics Warehouse. In fact, our only real challenge is keeping up with the overwhelming demand they fly off the shelves faster than we can restock them!
