The 45 caliber rifle utilizes a 30" rifled barrel
 
*We recommend a 4,100 psi air tank pressure with NSA .452 caliber 196 grain lead slugs for best accuracy. This combination will allow for an average of over 800 fps for a 3 shot string before needing to refill your air tank.
 
* Most .45-.452 caliber lead bullets will work for the air rifle kit but performance and accuracy can be variable.
 
*Air rifle includes mounted Red Dot Sight
