andythechicken Posted April 18, 2010 Report Share Posted April 18, 2010 Fitted an Eric brookes trigger kit to my CZ yesterday and boy what a difference it makes, cut out the creep and lightened the trigger pull. After I put the stock back on thought I check to see if barel was free floating. Answer - NO. Anyone recommend a tool or correct way of taking small amounts off the synthetic stock so I get the barrel to float? Thanks Andy Quote Link to comment Share on other sites More sharing options...

You can either rub a touch out of the stock with some sand paper, or put a washer between the stock and the lug on the front mounting screw. The synthetic stock is easy to sand so that would probably be the best way. When youve taken a bit out you should be able to slide a fag paper or a receipt all the way up between the barrel and the stock.

welsh warrior Posted April 18, 2010 Report Share Posted April 18, 2010 whats the reason for it free floating barrel ? Quote Link to comment Share on other sites More sharing options...
humperdingle Posted April 18, 2010 Report Share Posted April 18, 2010 Check the bolts. Try loosening both bolts attached to the action, and tighten the rear-most bolt first, then the forward one. This can make all the difference. Quote Link to comment Share on other sites More sharing options...
SSS Posted April 18, 2010 Report Share Posted April 18, 2010 The barrel is free floating to allow it to resonate consistently after each time it is fired. It makes it more accurate. I had problems with my wood stock, so I sanded the barrel channel down with sandpaper, enough to allow a £20 slide up and down with ease. Hope that helps, SSS Quote Link to comment Share on other sites More sharing options...
Billy. Posted April 18, 2010 Report Share Posted April 18, 2010 If you have a synthetic stock it shouldn't be floated anyway. Floating is done to stop a wooden stock from expanding/contracting in damp weather and subsequently touching the barrel in different places, changing the harmonics of the barrel.

It never was free floating on the synthetic CZ 452 I seem to recall, if yours happens to be, or not, it shouldn't be an issue, and if you put a bipod on it the chances are it wont be anyway!! ATB!!

Maybe you should tell Sako they are doing it wrong then as the synthetic stocked 75's and 85's have free floating barrels. Actually my synthetic stocked vssf also had a free floating barrel come to think of it. As both you and SSS state the principal reason is for consistent barrel harmonics. I don't dispute that wood expansion is an issue, as is barrel expansion due to temperature. They all have an effect. However it is just as valid to have a floating barrel with a synthetic stocked rifle as a wooden stock. The benefits of free floating a rimfire barrel are probably prety marginal though.

andythechicken Posted April 19, 2010 Author Report Share Posted April 19, 2010 Thnks all for the assistance. I'm going to try and float the barrel. It can't see that it will do it any harm. Cheers Andy Quote Link to comment Share on other sites More sharing options...

Cheers Andy No issues as such with either of these responses but "generally" with synthetic stocks rigidity is a problem, bipod bounce is well known....we all know it can be done but bedding may be a better all round solution if you have an issue...and if not, don't bother anyway! Lots of mays and ifs and generalisations I accept in my response, every situation is different! Quote Link to comment Share on other sites More sharing options...
