I googled the hell out of this and came up with nothing so I’m trying here.
Does anyone know the size Sabre drills their gas ports too on their mid-length 14.5’ barrels?
I’ve got the exact same question. I’ve got one and it seems a bit over gassed. I’ve switched to an H2 buffer and things are better but I’m starting to think maybe I should start using an H3.
Mine seemed a little over gassed in the beginning with a semi-auto carrier and a carbine buffer. The ejection was around 2 or 2:30. Now, with a full-auto carrier and a heavy buffer, the ejection is around 4 or 4:30. The gun has been 100% reliable and is very soft shooting so I doubt my gas port is oversized but I’m still just curious.
I’m going to get a new buffer spring from a known quality source. The one I have came with an M and A parts kit so who knows if it’s spec or not.
