Well after nearly 4.5 months, my Eform 1 was approved today!
PTR 91 12" barrel. Added a HK heavy buffer, picatinny rail and foregrip, and vortex spitfire 1x prism scope with red/green illumination. Stock is surplus HK.
Also added upgraded trigger group which brought trigger pull down to 4.5 lbs from 12 and noticeably less creep/over travel.
