Quick--need to order parts from Crosman today--need answers

[ray1377]

If I use a crosman steel breech that fits on a 1377 with my disco pistol build.
And I order the .22 disco barrel.
Do I have to order the disco breech and "barrel sleeve" for the disco 22 barrel to fit my 1377 steel breech?
I've been told the sleeve is just for the rear sight mount only.
I already have a steel breech and want to use a .22 disco barrel.
ALso when ordering from crosman and the part number for the vavle retention screws show you need 3, do you get three with that part number or have you got to tell them you need 3 of that part number?
Thanks Ray
