OP, while I am not generally a fan of the AR furniture on the HK, I must say that stock looks almost like it belongs there.
How is the cheek weld and sight picture with the stock as compared to the OEM?Yea, its the same stock I use on all my AR's pretty much ... its an ACS L so it doesnt have battery compartments to weigh it down.... feels really solid and doesnt look too bad
How much shorter then factory is this when collapsed?Id say it feels about the same, but with the longer LOP on the factory, it has me craning my neck too much. I plan on putting a red dot on it and with the stock it has me having to move very little.
Most of my irons/red dot are set on a 1/3 co witness so thats pretty much how it feels
