http://www.jamescalhoon.com/ Find them on the Price List page. HOWEVER, what they do, you can do yourself. Just re-contour the handle in the area where it is very thick. You can see the side-by-side photo on the page there. I've done this to a couple of my 452s, but haven't needed to do so on the 527s because I don't have any rings that are low enough, or scopes with big enough ocular bells to need the re-contouring.
Quick. About to buy a Cz 527 2.23 Rifle. Should I.

My experience with 4 527s (and about 25 CZ/BRNO rifles in total) has been that a lot of them need a bit of slicking up to remove burrs left over from machining of the raceway in the receivers where the bolt slides. Using some fine-grit sandpaper (I sometimes made a sort of "flapper wheel" out of sand paper or emery cloth, and run it in both directions with an electric drill), you can knock down any burrs from the raw machined edges. Afterwards, the bolts will just glide fore and aft when you tilt the gun about 30 degrees, and will not bind up when you push on the bolt knob to chamber a round.
With regard to the centerfire magazines in the 527 and 550s, I've had some that still had sharp edges remaining from when the feed lips were stamped, and would dig into the shell casings. For those, using some fine grit sandpaper to knock down the rough, sharp edge and round it off eliminated the snags, stopped the lips from cutting into the casings, and resulted in smooth feeding from the magazines.
I've never seen a problem from single-loading rounds, but I haven't done it much because I normally just feed from the magazine.

10 minutes with some 1000 grit paper will slick a 527 up very nice, same for the mags
Could be there are differences. Seeing as how I have one CZ in one caliber I'm by no means an expert on the species as a whole. But I did learn about not loading from the top the hard way with my new 7.62x39 model, which was made in January of this year.
Thankfully I didn't break anything, but I was wondering "What the heck is going on" when I couldn't close the bolt on rounds I tried to insert from the top into the chamber.
Upon close examination I discovered that the extractor is not spring loaded and doesn't move at all. After further experimentation, closely observing the mechanism while loading rounds from the mag I saw how the rim slides up into the extractor from the mag. Lesson learned and disaster averted. After some web searching I found stories from CZ owners who had broken their extractors before they caught on.
One thing for sure, I believe there are likely no two CZ 527s that are exactly the same. There's a lot of final fitting at the factory. When I looked into buying spare parts to have on hand, I learned there are at least 4 different magazine release buttons. A tech at CZ USA wasn't even sure which one I should buy, adding that the release buttons are factory fitted so I'd have to do some filing even if I did figure out which spare to start with.
But it makes me love the 527 that much more. I'm a DIY guy. I like making good things better, rather than getting something perfect from the factory... if there even is such a thing as perfect from factory from any maker of anything.
All the points you made are valid, but so far in my experience they all have a solution. Some things are just a matter of getting the rifle broken in from use. Other issues like sharp edges on the mag feed lips might take some fine grit sandpaper as Troy and I6turbo mentioned.
There's a fellow goes by ZRUS with a few CZ videos on youtube. Some are just fun to watch, some are very helpful. The one below is a must see for rough bolt operation issues. His solution worked like a charm on my 527. With either the factory bolt handle or the Glades it is slicker than slick. No binding at all now, but any binding I had on mine wasn't to the degree that I had to assist moving the bolt forward with my thumb. I suppose my 527 being not yet a year old it probably... hopefully has the latest design tweaks that fix the most significant problems of earlier models. He also talks about using Scotch-Brite to smooth the mag lips.

Not to pick nits, but directly from the owners manual: "Loading is also possible for single cartridges by directly inserting into chamber without use of magazine."
The extractor itself is a spring, and it can be adjusted by removing it an re-contouring it a little if it is too stiff to pop over the rim of a cartridge.
But yes, all rifles have thier set of idiosyncracies, most of which have simple solutions. I slicked my bolt up with some judicious use of a ultra fine diamond lapping compound, and it rides in and out like it is on bearings by just tipping the rifle forward or back.
I prefer to single load, so I use a bob-sled. It isn't because the magazines don't work. That said, even cleaned up, IME the magazines for .223 aren't the best. I don't have any experience with this rifle in 7.62x39 or 6.5G.

That venom has a 34mm tube. I have never seen 34mm rings for a CZ. That doesn't mean they don't exist but you might be stuck putting a DIP rail on it, and using picatinny rings.
The rings for a CZ will say they are for a 16mm dovetail.

You know that scopes gonna weigh more than your gun right
Something a with a 1" or 30mm tube will allow you to use more common rings, instead of a base and rings, or expensive not commonly available rings.
Id scope that gun as a carbine, which it is, with a lower powered lighter scope, and use it as such for now. Plinking at long range if you want.
Then at some point buy a long range specific rifle, for which that Venom, or something similar will be better suited.
If your dead set on going for a long range package with that rifle, and sticking with Vortex, then id suggest a DB tactical or Viper pst gen1, simply to get the 30mm tube.

Can't remember if it was in a thread or are pm's but me and loonwulf did quite a bit of looking for a near perfect scope to fit on the 527. Loon went with the Burris droptine I believe. I've been running a leupold 2-7x33-36 can't remember the objective size loonwulf kindly gifted me. on my carbine it's been great

I have a Leupold 1.5-4x with 1 in. tube on my CZ-457 using high rings for the CZ rail. I bought the rings at Scheel's - they're an in-stock item. The CZ-527 has the same sized rail, doesn't it (if my memory is working this morning)? You'll note this scope is a perfect match for my rifle as with those rings it just clears the rear sight, clears the ejection port, clears the bolt handle, and is far enough back for proper eye relief:

I built my own .223 precision rifle using a Howa 1500 HB action. That was about 5 years ago before everyone jumped into the bench rest precision rifle market.
If I were going there today I would just go buy one of these and call it good. The only thing to think about is the scope and bipod.

That's the same barrel and action I used and it's a winner.

Wow, that's an incredible price!! I built the same from a Howa 1500 .223 rifle into an Oryx chassis and spent a whole lot more than that!!
457s are 11mm and smooth, and the 527s are 16mm with a recoil stop notch.

Yes it is. I put a B&C stock on mine and it was way over 1K. Brownells used to have a good selection of Howa barreled actions but I think the Rona put an end to that. I went over there and didn't see any .223's or much of anything else.

I've 5 527s only had one that needed to return for factory repair had feeding problems due to improper fitting of the mag release. Mags can be tough to load but whatever you do don't do anything to the springs they're unobtainable if you break one. Also 7.62x39 and 6.5 Grendel use the same magazines
