Just curious to anyone who could help out on this snippet of curiosity i need to know weither or not i need to purchase this item or not at all.

Does the Savage MK II TRR-SR .22LR have a separate breach part of the bolt assembly, or is that a part i don't have to worry about when building one of these rifles from scratch?

Help is appreciated,

Thanks In Advance
