Sooooo, If there was a stock for sale that incorporated a built in barrel tensioner, would that be advantagous to greater accuracy? I dont know for sure, but I envision a device along the lines of a 22 match rifle like the Winchester 52D stock. It should allow the shooter to fine tune the vibration for max accuracy. Any opinions/thoughts? |

The barrel tension idea is to dampen barrel harmonics. With the research for building match rifles the US Army and USMC did with the M14, the 12 to 14 lb tension the unitized gas cylinder puts on a properly bedded conventional stock, those harmonics are dampened enough without doing a major reconfiguration of the M14. Putting on a barrel tension device would be a major reconfiguration. Personally, I like the look of that standard M14 platform to change it too much. |
Yes, there is a design that does that. Here it is. There is a tensioning screw under the forend that corresponds with a yoke. The results are in the pics. Take Care, Tony |
When dealing with the preload tension on the Garand barrel, it is upwards tension, and on the M-14, downward tension. The reason for the differences of the two is the way the stock interacts with the barrel middle ban/front hand guard clip. The other part of the equation is the fit of the receiver to the stock (cavity), and when glass bedding; both of these are set at the same time (barrel tension and receiver/barrel fit to the cavity and trueness in receiver/barrel down the forearm channel. So simply, just a tension device alone would do little in regards to group’s sizes if the receiver were not solid in the stock (read would have differences in barrel tensions as the receiver changes positions in the stock from shot to shot if the receiver is not solid in the stock). |
