Important to know
Marauder long screws for tube mounting not included!
Barrel Bushing with air transfer port already installed to use barrel blanks without air transfer port. You need to make pellet entrance (just make a little cone in barrel)
But if you will use regular Marauder barrel just put this Bushing away from the breech.
Also barrel hole in breech is 10.98mm but Standard Crosman barrels are 11mm and the diameter varies.
So you must machine your barrel approx. 72mm length to 10.96mm diameter.
It's done so to make sure barrel always tightly sits in breech.
For .25 Cal there is 12.7mm barrel hole in the breech.
For .30 Cal there is 15mm barrel hole in the breech.
Due to our laws, all breeches are marked as .177 but are actually whichever caliber you ordered.
.25 and .30 Caliber breeches can only support our magazines that are included.
