I think my barrel will be fine and drop a factory 123 SST round after some more shooting.
Some of the group buy barrels are probably OK.
I polished the throat a lot and now all I see is a few small scratches on a 123 sst when seated to factory spec and they seem to be made by a little roughness in the throat on one side.
That is probably what is holding the round from dropping at factory length.
My barrel shoots good and I must have got lucky.
A little JB's or Iosso on a patched 6 mm brush and some elbow grease might make some of the barrels work out and others might not see a need to change their chamber.
45r,
I wish you good luck with your Liberty barrel.
I moments ago checked the MidwayUSA.com website: AR-Stoner Barrel and Bolt AR-15 6.5 Grendel Medium M4 Contour 1 in 8" Twist 16" Stainless Steel, Product #: 884877, "$256.19, Save $43.80 (14%)." http://www.midwayusa.com/product/884877/...less-steel
Compare today's price with their price on that same item reported in these Pages, on February 7, 2014, "$274.96, Save $25.03 (8%)."
I also checked the SaternMachining.com website to see if they've posted clarification re their short-throated barrels, as promised back on January 30, 2014: nothing yet http://saternmachining.com/
