BAR not cycling?

[alpha6164]

I own a an FN FNAR which is a .308 semiautomatic made by FN. It is basically the BAR with a pistol grip and cold hammer forged barrel but the action is all BAR. I sent my rifle to a gun smith to have the barrel threaded for a muzzle brake installation, and after i have received my rifle back it will not cycle.

It has basically turned my rifle into a bolt action. I know Browning themselves that had the BOSS system as a muzzle brake. I dont think it is the muzzle brake that is the root cause. I believe that during the barrel removal and assembly something is not installed correctly and not allowing the gas system to operate correctly.

Anybody familiar with the workings of the BAR that can shed any light i would highly appreciate it. Thanks.

Here is a video of another member with an FNAR with the same muzzle brake without having any issues.

Here also is the FNAR manual which is pretty much identical to the BAR. The only difference i see is that the BAR has a gas cylinder screw cap that has to be removed and the FNAR does not.

I know next to nothing about the FNAR version of the BAR.

However, Browning has always recommended the bolt not be removed by anyone other then a qualified gunsmith or the factory repair center.

I have had BAR's down to the last spring & widget, and they could be right!

There is also a gas orifice adjustment screw in the gas cylinder you should never mess with.

If the barrel was not reinstalled perfectly the gas port may not be lined up with the gas tube orfice.

Have you contacted the "gunsmith" who did the work? While you're at it, you can ask him why he doesn't test-fire his work...
