SA National Match Type II

[Bob Seijas]

That's a very interesting subject... old shooters thought the poppet type could leak gas and cause uneven performance, so they wanted the old solid type. SA bowed to this desire and the SIP 200 said the solid type was "preferred" when available. It not specified as a requirement because they insisted that the valve type did not leak gas. However, when IHC had its function problems, one fault was traced to leaking gas cylinder locks!

Stock were generally not sanded by SA... I say "generally" because I have not seen one that was sanded but, under the heading of "never say never," I can't swear to it.
