Does anyone have preference and why?  M&A Parts advertises Wilson match grade barrels.  I'm pretty sure that J&T Distributing and Model 1 uses the Shaw barrels.  Is there any significant difference?  

Also, does anyone know which barrel RRA uses, is it of their own manufacture?  Thanks,

Rock River uses Wilson.

I still don't understand why you can't get a Chrome-lined Bore and Chamber from RRA....especially since they use Wilsons.  Everyone else that uses Wilsons provides Chrome Lining as an option....anybody know what Gives here??

Thanks,

Well I had a model1sales Shaw barrel SS heavy barreled gun and a RRA DCM upper with SS wilson barrel

(both uppers were the same except the RRA had the DCM tubed handguards.)

With a properly mounted 9power scope the Model 1 Sales shot 3/4MOA

With the irons the RRA shot .4MOA

[b]The quality of the RRA's bore seemed to convince me that it was a higher quality barrel.

The RRA cleaned easier meaning that it probably had a smoother interior finish.

The RRA barrel is bead blasted and the model1Sales barrel is provided mirror polished and easilly scratches. [/b]

The Shaw chrome moly barrels have shitty bores (lots of surface imperfections and circular marks running perpendicular with the bore.) I was not impressed with the quality of the 3 bores I had that were chrome moly so I sold them without ever firing any of them.

It's not scientific but I say go with RRA/Wilson

i believe the SS Wilson barrels come lapped, which decreases greatly break-in time and increses accuaracy out of the box.

Thanks for the imput.  It's an RRA upper for me.
