The QC from Army is horrendous. You might get one that will work great and need very little work, or you might get one with a ton of problems. If you read the review at arnies, it appears most of them develope problems over time. If you want it as a project gun it isn't too bad, but for a reliable primary or backup, I would stear clear. For $460 (or whatever shootsoft's price is) it's not bad.. but it's not amazing either. I'm probably going to wait for the ICS one before I get another L85.
PM me if you want specifics on the issues I encountered with mine.
