Guys, I got in a PSG-1 stock, but it has a heavy G3 2 stage buffer in it. Thought maybe someone swapped it out, so I went to replace it with a standard PSG-1 single stage buffer. When I removed the 2 stage heavy G3 I noticed the hole in the metal and stock is HUGE. The rear bolt is also a huge hex head with a massive washer. The PSG-1 buffer is the same length but it does not have any support on the walls of the tube when installed like the G3 2 stage heavy. The G3 2 stage heavy fits like a glove, nice tight fit in the tube, but the PSG-1 buffer has about a 1/8 space on both sides when centered. Anyone taken one of these apart. Is the hole that big in all of them? I have never had reason to check until now, and this is the only PSG-1 stock I have in stock at the moment. Did Hk ever make any special with 2 stage buffers or did someone just do an old swap-a-roo? Date code is "4IJ" on the stock.
Any info would be great. Thanks
