Barrel identification

Got this barrel with an original spyder today. It has no markings whatsoever, but it reminds me of a Lapco.

Might be something I&I did... Lapco wouldn't have done the big slots.

Big slots on an old Spyder make me think CMI. However, that doesn't look like the CMI Thunderpig barrel I remember.

Looks like something that would have came from I&I we had tons of spyder barrels like that. Lapco style porting would have probably been something they would have tried to copy as well
