Swarovski marks their optical devices with various acronyms which indicate the presence of a certain feature. Our customers often send us questions regarding their meaning, which is why I have decided to do a list where I explain the meaning of each existing acronym that Swarovski uses for their products.
W – the device provides a wide-angle view
B – the device features twist-up eyecups
GA – the device features rubber armouring
L – the riflescope is mounted on the rifle with rings
SR – the riflescope has an SR rail for mounting purposes
P – the riflescope has a parallax turret (side focus)
BT – the riflescope comes with Swarovski BTF ballistic turret
