I recently purchased our first precision air rifle, a used Walther LG300 and it came with two filling adapters. The manual says that one adapter is for a 300 bar cylinder (which is what we have) and the other adapter is for a 200 bar cylinder. The only problem is that we don't know which adapter is which. The big question is how do we tell them apart and which one is for which cylinder?
The longer one is the 300 bar adapter, they will both fit on the Rifle cylinder, but there are two types provided, one is for a 300bar charging cylinder and the other is for a 200bar charging cylinder
