Good Lord! Does anyone think that Glockfan is bitter, or is it just me?? Again, sorry you had a bad experience with Oly, but that does not make all Oly products crappy, and all people who deal with Oly idiots. Try them again, perhaps you'll have better results.
I have been dealing Oly parts for 10 years or more. I have had bad experiences, yes. Oly has settled them all professionally. On the other hand, I have had bad experiences with Armalite, DPMS, RR, and even the expensive guys like Wilson and Les Baer.
Reference to this thread: Oly makes an EXCELLENT barrel, and in my humble opinion, the best, most accurate AR barrel out there, custom or otherwise.
Also: Ultramatch barrels (marked SUM) come standard in 1x10, but are also available in a 1x8, and 1x14 twist as well. All you have to do is specify the twist when you order. !x8 or 1x10 is the same price on the PCR-1. The 1x14 would cost additional money.
On the other hand, the PCR-8 is a button rifled (still excellently accurate, but NOT an SUM barrel) in 1x9. It is also available in 1x8.
Oly makes their own barrels in house from 416 SS bare stock and has more options that any other manufacturer out there.
