The Rugged Suppressors R3 1/2 X 28 Flash Hider does not have a pin hole pre-drilled from the factory to allow for pinning and welding.
Yes, this should fit to the Ruger PC Charger.
The Rugged Suppressors R3 1/2 X 28 Flash Hider is 1.9" in length and weighs 2.9oz.
Yes, the Rugged Suppressors R3 1/2 X 28 Flash Hider is compatible with your Ruger LC Carbine in 5.7x28mm.
The Rugged Suppressors R3 1/2 X 28 Flash Hider is compatible with the Rugged Radiant762, Surge762, Razor762 and Micro30.
The Rugged Suppressors R3 1/2 X 28 Flash Hider is only listed as compatible with the Rugged Suppressors Radiant762, Surge762, Razor762 and Micro30. I would recommend the Yankee Hill Machine Mini Phantom, which is compatible with the Turbo K, and can be found by using the link below:

Yes, this muzzle device will work with the Radiant762 suppressor.
No, this will not as it is too short. The correct flash hider for pin and welding is FH013 which OpticsPlanet does not sell at the moment.
It will if your barrel is 1/2x28 threaded as this muzzle device is for 223/556.
