My CZ 512 Tactical in .22lr was made in June of 2016, you still have to have the safety OFF to pull the charge handle so no change was made there.
Below is my review at rimfirecentral;
I bought a new CZ 512 Tactical in .22lr and I must say I'm very satisfied with my choice of this rifle. It was made in June 2016. The trigger is very nice out of the box, it has zero trigger take-up, there is a bit of creep then breaks clean at 2lbs 11oz out of the box.
The upper receiver is aluminum, the lower receiver is polymer. The complete handguard, top picatinny rail and stock tube are aluminum as well. The stock has 6 position adjustability along with an adjustable cheek riser. Barrel length is 16.5", true barrel, no sleeve.
The rifle comes with 1 25 round magazine, the additional mag was 45.00. Mags are easy to load right up to the 25th round.
Disassembly is pretty easy IMO, the rifle is pretty modular actually. I disassembled it prior to use and lubed it up, there was no factory lube.
I put my AimPoint CompM2 on it along with an AR muzzle brake I had laying around. With the AimPoint red dot and the muzzle brake mounted my rifle weighs 7lbs 5oz's.
CCI SV 40gr ammo cycles quite well and is quite accurate, I did have some Win 555 bulk ammo and found my CZ doesn't care for lose tipped ammo. Edit, I tested 250rds of Federal Champion 40gr LRN, so far these are the most accurate out of my 512 and they cycle perfectly as well !
In the future I will work over the hammer and eliminate some of the creep, I am waiting on a fresh ceramic stone in the mail. I have re-arched the trigger spring and brought the pull down to 2lbs 6oz's...
CZ must have made some changes along the way specially in the trigger group and recoil system. My model only has one recoil spring, the manual shows 2, the actual trigger and hammer are a different shape/style compared to the ones in the parts break down in the manual as well.
The only con I have at this point about these rifles is the high price, they run $799.00-$899.00 CDN, never thought I would have that much tied up in a dam .22 lol.
