I just ordered a Magpul UBR despite my aversion to spending that much for a stock. The main reason I did so is because of the excellent Customer Service I have received from Eric of Magpul in dealing with my PMag issues.
Based on my experience, I know that the price tag is well worth it because it is for a great product that is backed-up by excellent Customer Service.
FWIW, the thread I created to share this information here on M4Carbine.net was locked before we came to a conclusion. IMHO, the moderator who did so did Magpul a great dis-service. I had requested that it be unlocked so that I can add in an update but I never did receive a reply.
