  1. I did not have a problem with the lower, so maybe you will be fine.  However, I purchased one of their LAR-15 Operators and a LAR-8 Operator in 7.62 almost 5 years ago. I had my upper receiver crack (unknown reason) on the LAR-15 and sent it back to RRA. They would not honor the warranty. I proceeded to sell the LAR-8 and went with a Spikes Tactical build for my 5.56 and one of the new DPMS G2s in .308 Its not worth my time to mess around with a company that does not stand behind their product 100%

  2. Great job videoing this build.  Several great ideas for getting it put together without using any special tools.  Only one thing I wish you would have showed better was installing the rear takedown spring.  Reviewing the video helped visualize it but would have been a bit better to have seen it as you did it.  Right around the 12:30 to 13:00 minute range.  Great job though.

  3. what are those pliers called? and did you have all your parts C coated or buy them like that? i looked through the comments and didnt see a response. im building my third lower and want to try those pliers. looks way easier.
