Im looking into swapping out the 300 blackout barrel on my mk18 mod1 to an 11 inch 6 arc barrel. The couple sites im looking at allow you to choose the gas tube length for the barrel. Options are pistol, carbine and midlength.
my concern comes from way more experience with 556 than 6 arc. I know i need to account for dwell time. My goal is to keep my mk18 clone but upgrade to a better round. It will be suppressed with a sandman k.
can someone with way more arc experience school me on tube length for 6 arc barrels? Id love to go mid length, but i know mid on 556 requires tuning. I want to avoid adjustable gas blocks, lighter springs or buffers, etc.
current set up for consideration.
geissele braided H1 buffer and braided spring, SSA-E trigger, PSA grendal BCG, geissele CH, deadair brake, sandman k.
running either 108 ELD-Ms or 77 grain cutting edge bullets.
all advice is appreciated.
