A little while back there was a thread pertaining to scope rings on a CZ 550 and I remember it was mentioned that some of the CZ rings would get loose. Iv'e just installed a decent 3x9x40mm on my new CZ 550 in 30-06 and have not even had the time to shoot it as yet, but want to ask, could it be that the CZ rings that wouldn't stay tight were QD? The set I ordered are just the standard rings and look like they should work fine. I think I'll put some loctite on all the threads, tighten to the inch poundsreccomended by CZ and hope for the best. Any feedback from some of you other CZ owners? Suggestions? Thanks -----John H

From what I've heard, the aftermarket CZ rings are hit or miss; IME the factory rings are the way to go, they are hell for stout, never loosen up, and fit perfectly (my 550 is a .270 with a Zeiss Conquest mounted with the included rings, I love that rifle)

I guess I'm a little surprised that these CZ big bores use a dovetail mounting system as opposed to drilled and tapped, butas you noted the mounts from CZ seem very sturdy and with using a small amount of loctite, I'm going to be very surprised to see anything shoot loose. We went on a trip before Iv'e even had a chance to shoot it and just got back so I'll get out to the DNR range soon, if it ever stops raining.I'm thinking with the reduced recoil loads from Remington, it ought to be a great varminter here in the midwest. A few years ago, I hunted ground hogs with a 700 ADL in 06 using factory 125 grain ammo and was amazed at the ranges at which you could take them.Sort of the best of both worlds, a decent flat shooter for the varmints and enough power for some of the larger game in one rifle.........John H

The double square-bridge Mauser action with locking dovetail scope mounts is just about the most robust and reliable scope mount system (and rifle) ever devised, the only thing it lacks is flexibility; but if all you want is a securely mounted conventional scope, that you wont remove, there are few that are better. I've owned my 550 since 2001, and swithed in the Zeiss in 2004. I have not had to touch the scope since I mounted and zeroed in in '04. Justmakeup more new batch of the same old handloads, and send 3 downrange into a dead center POA cloverleaf before each deer season.

Use the factory rings with GOOD glass and you'll love that rifle.

I added a touch of loctite to each screw in the mounts and rings so I'm sure it'll be fine. Sure pleased to see these threads commenting on what a great choice this rifle is. Showed it to my neighbor and he ordered one. He also did something I'm not sure about. While checking out my gun, he held the trigger and then closed the bolt in such a way that released the pressure on the firing pin spring.I made the comment that billions of bolt action rifles sit in gun racks with the tension on the spring with no ill effects so I didn't see that as a good thing. Also, with CZ's set trigger system, it's probabely not even a good idea. The bolt was very hard to open after he'd done this and I'm hoping that his little trick didn't do any harm to the mechanism.Any comments on this?

That is the proper way to close an emptybolt action rifle for storage, even one with a single set trigger.The 'hard to open' you are noticing is the rifle cocking the striker. This is normal, and happens everytime you shoot the rifle whether you notice it or not. I release the strikers on all of my firearms for storage, doesent hurt and can only help.

Just a side note, I'm getting the idea you're new to this rifle, and dont quite know your way around it yet. See that button on the left hand sideof the bolt shroud? close the bolt on an empty chamber, leaving the rifle cocked. Press and hold that button while you lift the bolt handle. Now you can unscrew the shroud and striker. That is how you field strip the bolt for cleaning.

IF you proceed as you have outlined, you should have no trouble at all!

I use 3/8" rimfire dovetail scope mounts with perfect satisfaction on some heavy recoiling muzzleloaders. Scopes stay put.
