S1 stock... - UTG Pro AR15 Ops Ready S3 Mil-spec Stock Kit

Bought the S1 version with the buffer, spring and receiver extension and I must say all of it is excellent quality. The S1 stock has a very neat look and feel the way it snugs up to the castle nut on the extension. The stock has a very dense and high quality feel to it. The buffer tube and spring are also very high quality and seem to be on par with some of the higher end buffer tubes I've purchased in the past.
