BRNO Rifles

[el Godfather]

Hello:
I have a general question regarding the quality of BRNO rifles. As I mentioned in an other thread that my .243 Win BRNO bolt is not as smooth as I would like it to be. It seems like there is some friction while moving back and forth. Friction like as if it is not oiled. I tried lubricating it but the problem is still there. Once COVID is subsided I will ask a gunsmith to look into it.

My brother has a 7x57 in BRNO and coincidentally its bolt also feels the same. Do we have lemons or they are what they are?

I will check again but I think both are made in Czechoslovakia i.e. old lot.

What are your experiences and thoughts?

Please post pics if any showing bolts if they have a similar problem or specific parts that can be tinkered with to fix this issue.


Thank you

They are made very well, there are a number of things that could be preventing the bolt from being as smooth as possible. So many things I could type all day and it still not be the problem without being there. One other thing are you used to a crf mauser style bolt, unless it's been highly polished and don't fight it still won't be as smooth as a push feed like a Remington.

Another thing I've seen is with some shooters not pushing the bolt properly, and making a nice smooth bolt catch and feel hard to work.

In a day light I will day some pictures of the bolt and post them here. I could see three things from a quick inspection. 1. A long line on the bolt showing its being rubbed consistently at the same point against something. 2. There are small lines inside towards the left of the bolt right where the magazine meets the frame. 3. Among other frictions the initial push is irritated against magazine plate.

This will be my project and would like to fix it myself without taking it to a gunsmith as its part of owning the rifle.

Thank you

Those last two points are excellent points. Mauser style bolts will feel different from push feed Remington's. Not saying this is the case for OP but you can have a smooth bolt and still have friction. I've met a lot of guys who think a bolt stroke should feel like pushing a finger through air.

I’ll triple the suggestion that CRF bolts feel rougher than push feeds. BRNO’s are excellent rifles.

If you have a scope mounted you may want to remove the bolt and poke around inside the top of the receiver for a potential long mounting screw. That can bind a bolt and scratch a line in it. Otherwise agreed with above.

Yep, I’ve had that happen once.

Here are some pictures for you all. May be there is something you could suggest.

There are a lot of machining marks in places I would have expected at least some factory polishing. If you can find a year of mfg. for this action, I'm betting it will have been in the Commie era.

It looks like you've a particularly long, shiny area on the extractor -- if you're familiar with removing and replacing Mauser-type extractors, you might try running the bolt without it and see if that removes most of the friction. If that's dragging against the right side raceway of the receiver bridge, it could make the bolt throw pretty sluggish.

Is the bolt numbered? If so, does it match the receiver? Same with the extractor -- I wonder whether it is off a stock Mauser 98? Possibly some replaced parts weren't closely fitted?

The underside of the extractor next to the bolt lug looks rough. A bit of polishing with a hard stone and oil should work wonders. Also take a look at the receiver where the extractor moves back and forth as the bolt is opened.

The bolt is numbered and it matches the rifle.

here is the midel number of the rifle.




I dropped the magazine open and the bolt moves much smoother then before. Still not to perfection as I would like.

seems like this is was one of the problems.

Any suggestions what to use for polishing it

The follower is just how they are, polishing my help, it needs the spring tension to feed properly.

I understand the tension requires to force the round up but while the bolt is moving on it should have smooth pressure not irking friction like there is lack of lubricant.

Try polishing the small spots were its touching, i

Shoot it....a bunch! .... It'll smooth up!

The follower won't rub when it is loaded . Yes polishing the race ways, a tedious chore, will smooth the gun up.

 

[troy fairweather]

The wood painter sticks work good for polishing the raceway

I'd like to buy a vowel....

I've always heard good things about them, surprised it looks so rough inside.
