Which Air Rifle to choose?

[ruckspring07]

I am new to the Air Rifle Competition Community; and entering the VA Adaptative Sports Program-Air Rifle to compete. Maybe joining other Veteran Air Rifle organizations later. I am looking to purchase one of the following:

1. Walther LG400 Aluminum Competition Air Rifle with Sport Sight
2. Walther LG400 BLACKTEC Air Rifle
3. (FWB) MOD 800 Aluminum Air Rifle
4. Feinwerkbau (FWB) MOD 800 Evolution Top Air Rifle

Which one would you recommend?

Thanks
