A nitrided 4140 steel clamp closes onto the rail, and the assembly weighs 57 g (2.0 oz).\u003c\/p\u003e\u003cp\u003eThe 509T is an enclosed-emitter dot, which is the reason a lot of British shooters pick it — the LED is sealed inside the housing, so rain and mud cannot bridge the gap and dim it. Putting it on a mount machined for its own footprint keeps the joint count down to one.
