Got the bipod shortened and the bipod feet rears chopped off and rewelded. Still need to blast and park the feet. Almost done...
As far as folding it back it works fine. The legs stay open wide when it rotates back and only come together when they are parallel to the barrel. There is no interference with the 30 round mag. There is also no interference inserting or removing the mag, although if I had made it the original planned length, there might have been a problem.
