This is the part number for the spring from ATI below.....

" Receiver Group Parts list # 51 / Bolt stop spring # 402.20.52"

However, this is the actual size of the spring if you look elsewhere...
.012x.12x.440

You can find them either at Mcmaster Car or EBAY

Thanks for the clarification.It does get hard to remember all the acronyms and abbreviations.

Sounds like IDOXLR8 has a good answer.
