The 45 caliber rifle barrel conversion kit allows you to turn your Serpent Arms 28 gauge Air Shotgun into an Air Rifle. The conversion kit includes a 30" rifled barrel with handguard and valve stem collar.
 
*Simply unscrew the set screw hidden under front picatinny rail bolt, Unscrew air shotgun smooth bore barrel assembly, screw on rifle barrel assembly, tighten set screw, and reattach front picatinny bolt. To attach valve stem collar, take off air tank, screw together valve stem collar onto small stem of air tank valve, and put the air tank back onto the airgun.
 
*We recommend a 4,100 psi air tank pressure with Powerbelt 45 caliber ELR 285 grain muzzleloader bullets for best accuracy. This combination will allow for an average of 800 fps for a 3 shot string before needing to refill your air tank. We have averaged 1.5" groups at 50 yards with this combination.
 
* Most .45-.452 caliber lead bullets will work for the air rifle kit but performance and accuracy can be variable.
 
*PLEASE NOTE: Watch the video for full instructions on how to exchange barrels.
