Sorry for posting this here but you guys are a lot friendlier than remingtonowners.com. I've been trying to find out what Weaver/Picatinny mount fits on my new Remington Model 750 and found that the prices vary tremendously. I've found 3. One from Weaver runs about $9 and has only a few slots - I think 2 in the forward end and 2 at the back. The 2 from EGW are $29 and $49. Both have a complete set of slots. All are 0 MOA so that not the difference. The cheaper EGW has a channel down the center whereas the other does not. What's the deal? They all look like they would start out from the same block of aluminum so it shouldn't be material. And the cheaper EGW looks like it should take more labor than the more expensive one. $9 to $49 for the same thing - CNC milling of an aluminum block?
