Alright, so I got an EBR (Mod 1 for standard weight barrels) stock, and the install is going great, and I get everything together and in the instructions it says to install the 3 button head set screws on the op-rod guide block. Here's my issue: there is only one place on the guide block that was sent with mine for a set screw, and it's on the bottom. After browsing through the EBR picture thread, I see everyone has 2 other set screws on the 3 and 9 o'clock positions on their guide blocks. All I have at those positions is a hole for the pin. Also, the instructions say that the barrel should be free floating from the guide block onward....my guide block's barrel opening is MUCH larger in diameter than the barrel itself. So, did I misinterpret the instructions, or do I have a part that I shouldn't?
The rifle in question is a Polytech with a standard weight barrel. After looking at all the pictures of EBR's in the picture forum, I'm beginning to think that maybe this op-rod guide block is for a heavy barrel?
Here's some better pics of the block, I took it out of the stock and rifle.
