Best general port size for MK18 build
Getting ready to ship my LE6920 off in the next month or so to be cut down to 10.3" for a MK18 build.
With the exception of the lower, all parts will be the exact same as used on real MK18's.
My only deviation would be the port size. I know .70 is the correct size for a true clone, but would it be better to run something along the lines of .80-.83 to accept a wider range of ammo?
Also, as my first SBR, is it a general practice to cut the gas tube down to fit, or do they sell gas tubes for 10.3" barrels?
Thank you for your time,
Garrett

Well it just depends on what you're opening it up to...opening the port to .083 is just a waste of a "known quality" barrel.
