I have a Leupold Mark 4 3.5-10x40mm on my Mcmillan 308. The scope currently has the bullet drop compensation (BDC) elevation turret that is set up for 168gr bullets. I was told the scope originally came with 4 turrets for different caliber bullets. My elevation turret has 1 MOA intervals however I see these scopes with 1/2 MOA BDC turrets being sold. My question is if I find a 1/2 MOA turret from someone that is not using the 308 caliber can I switch it out with my current turret and have 1/2 MOA intervals.

gunswanted,
NOPE, not that simple. Your internal turret cams are set to 1 MOA clicks, changing to a 1/2 MOA turret/dial will not change the internal cams. Your turret/dial is just an indicator with tick marks showing each 1 MOA click. You can put a 1/2 MOA turret/dial on it, but it is still adjusting internally @ 1 MOA per click.
BTW 1/2 MOA scopes from Leupold are called M2's. Your's with 1 MOA clicks is called an M3.
Depending on the age of your scope (post 2007), Leupold can convert your elevation cam from M3 to M2, for a fee.

NO the internals are different. The caps have nothing to do with it. The caps can be taken off by loosening/removing the three set screws and then you'll see how they attach on the inside. If you want a 1/2moa scope you'll need to trade scopes, buy a new one, or send it into Leupold custom shop if they will do it for you. If I were you I would wait till they start doing the Mil/Mil M5 knob conversions.

Thanks for the great info Bobin NC. I will call them tomorrow and run my serial # and see if I'm a candidate.
Thanks again.

The M5's are listed in the 2010 catalog I got from Leupold. The custom shop shouldn't be to far behind.
