    Any idea when you guys will be getting the MicroTUNE Gas Blocks back in stock?

    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?

    I tried one with my mws and wasn't able to install the firing pin in the carrier because the diameter was too small to fit the back end of the pin.

    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.
