Not cycling
Recently built a 300, having trouble getting it to cycle rounds. Bolt opens far enough to eject but not enough to grab a new round. Played around with the gas block for a while and couldn’t ever find a sweet spot. Wondering if the easy fix is a new buffer spring kit? Can’t seem to find any info on what the lower came with for a spring.
PSA lower with an HBPDW brace, Superlative Arms gas block, Spike’s pistol length gas tube.
