hi scottbefore it was an old type standard length 177 sporter, but fancied a karbine version... i didnt want to buy a new one so i sold my old barrell.....,stock,... and full length air cylinder, and bought a lothar walther karbine barrell, new custom thumbhole stock, and a lightweight air cylinder from MARKSMAN to make it lighter and better shot count, i get around 110 shots in 177, i also had a full service at REDBECK SHOOTING SUPPLIES
