For Xmas my wife got me a century c308 before California gun laws changed. Iam in the process of swapping out the furniture to all wood and ran in to a problem and wanted to see if anyone here has experienced this. I picked up a surplus German complete wood stock from either hkparts or try, can't remember, problem is won't fit my receiver? The metal backer plate that the op rod goes into does not align with my slots on the receiver. I then swapped the back plate from the plastic stock that came with the rifle because I know it slides on smoothly. The wood stock for in the metal great, problem now is the hole for the buffer housing do not line up between the metal back plate and the wood stick-up , the hole in the wood stock is approx 1/8" proud at the bottom, in other words when you look down thru the metal buffer hole, you see 1/8" of wood so that you cannot install the buffer? Has anyone else had this problem when switching to a wood stock? Since the receivers are new made by PTR on original tooling, I would think that it should be a direct swap? Any input would be appreciated.
