I've done a lot of research looking for a 7.62x39 bolt gun looking at Howa, Ruger, and CZ. I decided on the CZ 527 suppressor ready. I was well aware of the issue of the barrels not being straight in the synthetic barrel channel with many touching or almost touching the right side of the stock. As these complaints are all over the internet since 2017 you would figure CZ would have this corrected by now, right?
Well with no one having this gun on the shelf, I had to order it and sure enough, the barrel is almost touching the R side of the stock. You can put 3 dimes in the space on the left near the fore end, and barely slip a dollar through on the right. It is so obviously off it makes you wonder how it got out the door at CZ. Total bullshit on a 600.00 rifle. I've read that CZ is happy to fix this, but you have to ship the rifle and it can take 6 weeks. Also bullshit.
So, it appears the stock is warped near the fore end. I put the barrel in a vice and pushed the fore end to the right, shimming the right side of the barrel channel with a stack of business cards. I heated the last 4 in. of the stock with a hair dryer while gently prying the R side open with a popsicle stick. I let it cool with the shims in place and viola, the channel is now near centered, at least acceptable.
With the warped stock, sticking bolt that needed worked several times to function consistently, and decently light trigger with some creep and tons of over travel, my first impression of this gun is not good. They gave me a computer generated test target that shows 3 shots in the same hole at 50 yd with S&B ammo, so I'll hold off on my opinion of this gun until I see if it shoots up to the hype.
