For AT44 series rifles, please be sure to verify whether or not the air cylinder's valve spring cover is threaded.  The original AT44 series rifles used a white plastic plug, and require HA90420.  Current production AT44 series and BullBoss rifles use a threaded spring cover and require HA90435.  If you need assistance determining which item number fits your application, please contact our Service Department.
