Jerry wrote the rules for the EEM. (I'm usually wiped out by then, and often sleep thru the EEM match) and he specified the barrel mounted sight. He did not specify the stock type, though the full pistol grip stock is one of the defining marks of the A3 variant. As such I believe as the rule is presently written the Scant stock can be used on a 1903 with barrel mounted sights.
We do try to be inclusive on these things, and one of the purposes of the EEM is to enable as many folks as possible to be able to shoot this type of match with weapons many already have. It seems most anyone with a fondness for old American military arms has a 1903 and a 1911 in their collection. The barrel mounted sight makes for an easy definition and cut off.
Well, actually General Scout wrote most of it but with my/our input.
The regs for the EEM with regards to the 1903 Springfield simply say,
" Springfield Model 1903A rifle. Must have barrel mounted sights. WWII
style receiver sights are not allowed."We probably do need to revisit stock configurations.
I believe the sight protector was used in some forms fairly early so we're probably ok to use them, but I would like to do some research on that before I give final approval.
