I recently received my Larue Stealth upper. I got a 16 inch barrel with 11 inch rail. The fit and finish is excellent as to be expected. I currently put the upper on a POF lower which is a tight fit but I have a Larue lower coming.
I was a little surprised with the bolt carrier. After firing a hundred rounds I noticed some wear on the buffer. I was able to see a burr/rough finish on the back of the bolt carrier. It only took me about five minutes to fix it with a stone but this shouldnt have been needed. Another minor thing was that the flash hider wasnt perfectly indexed. It was only a cosmetic thing and most people wouldnt notice. I am going to put on a PWS comp anyway.
One thing that really impressed me about the upper was the alignment. I am using an aimpoint with magnifier behind it. I used Larue mounts for both. Because of the way I have it set up there is only about an 1/8 of an inch between the two optics. The tubes of the optics line up perfectly. I also liked that the adjustment for the optics and my backup irons was in the middle of their adjustment range after being zeroed. I know this isnt a big deal but it shows that the rail, barrel, mounts, and upper are all in alignment.
The upper functioned great. I had a problem with my reloads because I didnt size the brass down far enough. The rounds would chamber and fire but I couldnt extract them by hand without a lot of work. I adjusted my resizing die and the rounds work fine now.
I havent had a chance to really test the accuracy but I would say the upper is pretty comparable with one I built using a krieger barrel.
The only thing I dont really like about the upper is that the gas block isnt staked. I havent heard of anybody using a larue upper that had their gas block come off or loose. The problem is that I am guessing it would only 20-30 dollars to the cost of the upper if larue did it when they made it but if I want to have the gas block staked now I have to find someone that can do it and they will have to at least partially disassemble the upper and I will probably have to mail it off.
Overall all I am very happy with the upper. I plan on putting a few hundred rounds through it next week.
