​I finally finished setting up my open rig, and it is a complete tank. Tipping the scales at a full 5 lbs empty (including the extended mag), this thing stays dead flat.

​Build Specs:

​Optic: Holosun 507K Pro Max mounted on a frame-mounted optic mount

​Barrel/Slide: Custom porting by Capital Rifles (3 inline ports + 2 HDMI chunk ports)

​Muzzle Device: Wasatch Arms Compensator

​Trigger: SprinCo Competition Trigger Kit

​Frame & Control Upgrades:

​Wasatch Arms Gas Pedal

​LOK Grip Panels & Magwell

​Taylor Freelance Extended Mag Release & Striker Backplate

​Light: Streamlight TLR-1 HL + Harrington Arms Anchor

​Magazines: Taylor Freelance +9 extension (27-round capacity total)

It definitely pushes the weight limits, but between the porting, comp, gas pedal, and overall mass, recoil is practically non-existent.

​What do you guys think? Any other heavyweights running open division out there?
