Been looking at acquiring one of these with the intention of deheading and converting to headless - I already have the headless 5er system.
Found this video on YouTube...it's a bit disconcerting knowing that there are/ were issues that should have been resolved in Quality Control.
I recall seeing a couple for sale here and was wondering whether the issues were present on those owned by BCers.
