outlaw - personally, I do not. I have 2 of their uppers and they are extremely well made, and shoot like demons. You will find they (LMT) are generally considered "top" or a "tier 1" manufacturer along with Colt and Noveske. And they have more than earned that designation...with the right barrel steel, HP and MPI testing, proper carrier key staking, and a host of other qualities that I'm sure someone with much more experience than I will be along soon to expound upon...
I own their products, I use them regularly, and I paid "extra" for their name and have not regretted it.
