Gunsmithing Barrel free floating.

[Jscb1b]

I've got a bone stock remington 700 ADL chambered in 6.5CM. It has the synthetic stock. The stock has two bumps on the inside of the forgrip to provide pressure on the barrel. When I free float the barrel, how far back should I go. All the way back to the base of the barrel or to the end of the chamber?

Good question and you will get a lot of different opinions. I still havent decided on mine, but another 3 weeks until the stock arrives. I am thinking some 20 mil tape starting at the end of the chamber to the end of where the barrel contacts the stock. Then bed from the lug forward. That would free float the barrel to the end of the chamber.

When you remove those two bumps, that cheap stock will curl up and touch the barrel anyway. Throw it away.

I tried removing the pressure points on an old Remington ADL stock once and found out that the action bed was so low it caused the barrel to contact the stock forend anyway. I ended up having to bed the action to straighten it out. It turned out good but it wasn't as simple as I thought it would be.

If you do it, as supercorndogs said, it is so flimsy any forward pressure (bipod, etc) will probably push the forend up and touch the bbl anyway.

As a poor man's fix, you can sometimes glass bed a piece of stiff rod (steel or aluminum) in the forend to stiffen it up and help.

I would bed to the end of the chamber in a flimsy stock. But hopefully you know you're putting lipstick on a pig.

Watch the EE, sometimes you can snag a used PSS or other fiberglass stock for under $200.

I'd be willing to bet that if you hog tied a Rem engineer and fed him large quantities of NyQuil, he'd eventually admit that those two pressure pads are more intended to prevent the stock from slapping the barrel and sounding like a steel machinist scale being smacked on a linoleum kitchen table, rather than deaden any of the big fancy words used to describe vibration.

Sand em off and ensure you have plenty of clearance when the gun is under a load. (to mean you proned out, slung in, bagged up, benched, whatever) so that the barrel not biased during the shot event.

Hope this helps.
