I bought a new CZ453 "varmint" model (heavy-barreled, no iron sights) .22 rimfire right after they came out and I was able to see and handle them down at the big NRA National Convention in Louisville, Ky. and did quite a bit of shooting with it using a new 4-12x40mm variable scope before replacing the 4-12x scope with a 6-24x50mm scope off my heavy-barreled .222 Sako.
The M453 is a M452 with a completely adjustable, factory-installed single set trigger. I've never shot the Marlin Model of which you wrote, so I can't tell you anything about it. However, I doubt that any Marlin will be as accurate as the CZ452/453 models. Hopefully, some of the other Members here in the Forum will have some experience with the Marlin model in which you're also interested.
My M453 is currently at my gunsmith's shop. He is fiber-glass bedding the action and pillar-bedding the action screws (and leaving the heavy barrel floating). He is also going to highly polish the trigger guard & then give the trigger guard a deep "hot" blue job. This should make the otherwise ugly, dull, cheap-looking trigger guard much more acceptable looking (to me, anyway).
I'm surprised CZ would put such a cheap-looking trigger guard on a .22 rimfire rifle that has a manufacturer's suggested retail price of almost $600 ($596.50), but generally sells for at least $100 less than that!!!
The "varmint" model has a heavy barrel (better for consistent, multiple-shot accuracy) in both the M452 & M453... and all CZ .22 rimfires have hammer-forged barrels which are suppose to be "
THE" most accurate way to "drill" a rifle barrel. The "varmint" model is also somewhat easier on which to mount a scope since there are no iron sights on the "varmint" model rifles.
The CZ 452/453 are very accurate rifles, but much of the accuracy is determined by the ammunition the shooter uses. Unfortunately, "match" ammo is expensive, but the fun is to set up the rifle so it is as accurate as possible. This means you usually have to do at least "trigger job" on a M452 on the already-fully-adjustable trigger found on both the M452 and M453.
While the regular trigger on my M453 is smooth and just "ok" (maybe 2.75 lbs.), the single set trigger is set at just a few ounces... and so, no "trigger job" was necessary.
Once I get my M453 back from the gunsmith, I'm going to search for a brand of inexpensive .22 rimfire ammo that shoots VERY accurately through my CZ453. This is gonna be a "fun summer"... lotsa CZ .22 rimfire shooting!!!
