trueing upper receiver

[hugh]

What is the hordes opinion about getting a brownel trueing tool?
was thinking about pulling my LW barrel and resetting it...
shooting for group can make a guy nuts and flyers just make me insane when all of them go
to the same areas ...please tell me what you think.

I've seen flyers with LW barrels before, and it is quite frustrating. This reputation was related to me from guys who shoot a lot of long-range, and these types of issues seemed to be known about in BR circles with the 6mm and 6.5mm bores for some reason. I've seen one particular 6mm LW pipe that would shoot amazingly tight groups, then throw one way the heck out of the cluster.

I doubt it's your receiver. There's a thread on receiver-truing already, with the Brownell's tool and others referenced and discussed.

Flyers usually to the right...

Due to the floating boltface, In theory an AR shouldnt need and trueing unless it is way off.
