A new guy here but have two complete parts kits for an Aussie and Brit heavy barrel build minus gas blocks. If anyone has a hoard I have these last couple of builds to flesh out most of what I want in my FN/L1/L2 collection. Am not new to this but keep hitting dry holes on heavy barrel,gas blocks for past three years. Went through cancer in 2009 and sold a lot of rifles trying to simplify my estate and darned if I didn't live. Replacing some has been a chore that is still in progress.
