Always wanted to try this
I had a "little bit lighter than usual" Benchmark 30 cal barrel I traded into and an afternoon to kill before visiting the grandsons. The idea of applying tension to a barrel always intrigued me and using the muzzle-brake and about as much "stretch" as I could induce with a six inch Crescent ... I came up with this 5 shot group: I'm thinking to try it shortened considerably next |

Nice! It's like a Dan Wesson barrel...only longer!

Why mess it up potentially? Shoots good where it is at.

Nice group! Looks like it works.
Can you elaborate on how it is done? Hopefully I'm not looking over the obvious. Larry

The aluminium tube is as long as the barrel from the face of the receiver to just short of where the threads for the muzzle brake begins. A spacer that caps the tube provides a surface ( and the difference in length ) for the muzzle brake to "bear" against as it travels down the threads.... when you run out of room as you tighten the brake ( or the difference in length between the tube/cap and length of threading) the muzzle brake draws tension into the barrel.
Kind of the opposite of a turn-buckle when working with cable? Or similar to the way a garage door opener chain gets adjusted? Or the way an anchor bolt works to hold a sill plate to a foundation? Or the way a spindle nut directs tension against wheel bearings? Sorry it feels like I've come up short of vocabulary |

How much do you think you stretched the barrel with a 6" cresent wrench? Kenny

The whole experiment was supposed to culminate in a carbon fiber tube that also doubled as a fore arm ...... but dont let that get out, its a secret. Hawkeye, I made the mods to the tube in my shop after buying it as scrap from the recycler guy. Last edited by Spook; 11-03-2013 at 01:25 PM. |

Does not stretch the barrel, but provides tension to try to make the harmonics of the barrel consistent, shot to shot......helps to remove the variability.
