Clint,
Is there potential for port erosion and it open up or anything else associated with erosion.

There's always potential, but I don't believe it would be a practical issue.

TheMONK sent me the Gemtech carrier to let Mark and I run it. We ran it in several guns and we were impressed. My first choice would be to fix the port size, but this is a pretty cool fix. I don't know about the reliability of the carrier or how it will stand up, but it made a nasty ported gun like a dream to shoot.
Many thanks to the MONK. I am considering trying it in my LMT MWS 7.62. Anyone try theirs in a 7.62 gun? street cost?

Odd. They must have spec'd it off the the small spool firing pin. To Gemtech's credit... the carrier worked exactly like porting the gun correctly. I don't know what, if any, long term usage issues you might face, but it very clearly changed the bolt speed.
I do remember ESK saying something about favoring the gas correction at the barrel port instead of in the carrier/upper area. I forget exactly what his concern was.... gas turbulence or expansion chamber side affects maybe..???

I believe the earlier in the system you cut the gas, the better, it will reduce smoke at the carrier key / gas tube connection, and reduce noise compared to the SBC. I'll look again but I'm certain I recall that the SBC diverts and vents the excess gas out the end of the valve shaft, which = noise to the shooter. You don't have that when you simply stifle the gas further upstream.
Which is not to say I don't like the SBC, I found it very convenient.
