Rifle Scopes One piece vs two piece scope mounts

Re: One piece vs two piece scope mounts

I big advantage to 2 piece in my opinion is if you're going to top load the rifle then the base isn't in the way of your fingers. If using a DM setup like AICS that can't be top loaded then I see no reason not to use 1 piece.
 
Re: One piece vs two piece scope mounts

I first went for 2 piece 20MOA bases but found that the bases were not perfectly aligned or that the slope did not give me all of the elevation I expected from a 20MOA base. These were Leupold Mark 4 steel bases and I tried 2 sets so it wasn't cheap stuff. May be just the Mark 4 stuff or maybe my receiver is way out of whack but when I switched to a 1 pc Mark 4 base I got better alignment with the barrel and 5 more MOA of elevation on my 700. As jasonk mentioned, I'd like to go back to a 2 pc at some point to give me more finger room so perhaps next time I'll give it another shot with a different manufacturer.

Yeah, I hear you on that part right there. I am NOT a fan of Leupold, but I can tell you without a shadow of a doubt that the fault does not lie in their court on this one.

I'm guessing it was a Rem 700. I'm not sure about the SS actions, but I know the blued ones are hand polished. Which means that they will all be different. After my last build, I've totally given up on Remington ever producing a STRAIGHT action right off the get go. Some may need minor work, most will need more.

I now bed every base I put on. I'd like a two piece on a Remington. It would be nice. But it just allows for too much tweaking on the scope tube. You end up with major scope rings unless you use something like the Burris Zee rings with the inserts to keep the scope from being mashed up.

There are even receivers that are so out of whack that the one piece bases flex and bend when installed without some sort of bedding. There is a thread that discusses this at length. ETA: Here is the thread

I love the Rem 700. I think it is a time, battle, experience proven platform. People still base their designs on it. But from the factory, they just aren't straight. A bedded one piece base is the way to go.

depends: a 2 piece Leupold will be better than 1 piece chinese...i think that a good facture 1 piece is the best for our rifle
 
Re: One piece vs two piece scope mounts

If you are mounting it on a custom action that is trued and you get really good quality 2 piece base then for the most part it is not a big deal. A 2 piece base will have TWO center-lines and a 1 piece base will have ONE center-line even if you put it on a rifle that is not trued. Also another advantage for a 1 piece base is if a screw comes loose you will have more contact points to hold it solid.

Re: One piece vs two piece scope mounts

A one-piece done right is the way to go IMO. I don't care too much for QD's though. I want the rail, rings, and optic to act as one solid block of metal.
