[QUOTE="ARlife4me, post: 2865088, member: 105694"] I want only experienced Smiths about gas port size, location and cartridge specific to help out this/these question/s please. Other people with 1st hand knowledge can/could help also IF they know their port size! Some of my barrels I know port size on only due to manufacturer list it and depends on gas system length thereof. While I have many 6.5creeds in AR's, not all function well with standard carbine/rifle buffers and springs. This also translates to other 308 based cartridges of .473 bolts (anything with that bolt face, but not necessarily 308 based).

I also have "camgas" systems (+2) in 260rem and 6.5creed that DOESN'T function as well until other mods are done. Is there a good way to find out what the port size is without going to a Smith?
