thinking of purchasing a PCR-1 Ultramatch. would appeciate so feedback on this rifle. accuracy, quality, pros and cons.

I have a SUM barrel, 20", and it is probably the most accurate barrel I have.  The SUM's the probably the most accurate barrels you can get without going custom....

I have not scoped it... so I dont know exactly what it is capable of, but bench rested, with match ammo, and I was able to do 1.5 MOA with iron sights.  I have never been able to do that before.

I wouldn't part with mine for anything!

I've got a PCR4 ultramatch,H-Bar 1 in 10 twist SUM 20 inch, and 4 x 12 scope. Shoots fantastic.

I got the PCR rifle kit in the 20inch A2 and slapped it on a stripped RRA lower.  I am VERY impressed with the quality.  I have only fired it once, about 150 rounds, this past weekend.  Functions flawlessly and the accuracy was pretty darn good, and I'm sure it'll get better as I get better!
