Used but not abused, dpms/sr25 pattern 18" 308 barrel that is 1x11 twist w/ midlength gas system. Little over 500 rds through the barrel, for me she has been very accurate w/ 125gr projos and 4064
(.5" groups). I am including a syrac gen 1 clamp on GB w/ gas tube, I have had no issues w/ this gb system it has made this build real smooth.
$280 shipped
