God I wish the old board was still accessible if only for the archive of info. regarding every question anyone is ever going to ask (and my 3,800 some odd posts).
Ok I have a Carbon 15 Pistol. After about 300 rounds one of the staked screws that holds the gas tube on top of the bolt carrier broke.
I didn't have faith in any "customer service" (I should have) so I screwed around for 6 months before I sent the broken bolt carrier back to them on a Thursday.
On the following MONDAY I had a new bolt carrier in my hand. Professional Ordnance is in AZ and I'm in Texas, and shipping aside that's damn fast customer service. I also sent them the carbon fiber buffer tube that I had screwed up, and I told them I broke it and I didn't think it was covered by warranty since if I'd been watching what I was doing it wouldn't have broken. I gave them my credit card no. and told them to charge a new buffer tube to my account.
Hell they sent me a new buffer tube and didn't charge me for it, or the virtually next day shipping.
Say what you will about them, but they got a customer for life in me. I've never been treated so good by anyone.
And thier firearms aren't bad either. After I replace the bolt carrier and buffer tube - no more problems after another 500 or so rounds.
This thing KICKS @SS!!! No it's not the most accurate piece in the world, but I am getting better with it every time I shoot it and I don't even have an after market scope on it yet.
It is "mag picky", and the mags that work best in mine are the "Eagle" clear pre-ban high caps (made by the Beta Company of Beta C fame) if you can find them and no I'm not selling ay of mine. Good milsurps will work, but the "thermold" or whatever they ship it with is not the best mag for the pistol IMHO.
Anyway, I have a lot of guns, but next to my AUG's, my Carbon 15 pistol is my favorite to shoot and the most fun.
I guess you could say I recommend them.
