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
