suppressed gas tube length

[trophyhunter]

I had this posted in the suppressor section and no answers...lets try it again

I have a 20" 308 that I want to shorten down to 16" for weight and overall size. It has a full length gas tube right about 14.5". This rifle is shot 100% with a 762SD attached.

My question is will there be an issue with the gas tube being this long while shooting suppressed ?

I would suspect it may run better suppressed but you may have issues unsuppressed (under gassed).

Re: suppressed gas tube length

thats what I was thinking, it would be similar to slowing down the gas pressure. Is this what they call "dwell time" ? Time bullet spends in barrel after gas port
