Matador Ar9 pistol on a Juggernaut tactical 80 with some Strike Industries and regular mil spec lower parts. Uses Glock mags. No muzzle device. It's been a fun one just moving on to another project. Ran it suppressed 90% of the time. Maybe around 2-300 rounds through it.
$650 with SB brace.
$600 without brace.
Also have a nice A3 compact pic rail angle grip that fits perfectly for $30.
