Based on the fantastic models by AtThyRightHand (Armthyrighthand) -

-Added 1 degree extra cant to the magwell, tightened the sides and rear to require hand filing after print to eliminate mag wobble and feed better to my (homemade & likely out of spec) barrels

-slightly elongated the feed lip profile, adding extra reinforcing walls on both sides

-added a 2mm hole for a pin across the top of the magwell area so the mag doesn't beat on the plastic over time

-extended and reinforced the area around the bolt stop pin tower to eliminate shearing and further support the ejector

-added a hole, internal and external recess for an m3x5 screw and nut on the right side next to the hammer pin head to prevent the hammer pin from walking out

-Selector physical lockout at the safe position

Optional for NFA purposes or states that require a serial number:

-added recessed window for steel serial number plate
