Easy Entry to Join the .300 Folks December 20, 2016
Reviewer: James Guidry from Butte, MT United States  
This is the absolute easiest way to get into one of the latest and most popular calibers to break on the shooting scene. Using the lower receiver from your existing AR, simply replace the current upper receiver with this well-built complete upper assembly.  Still easier is to drop in the BCG and charging handle. You are ready to go!

Having built a few ARs over the past few months has been made so much less of a hassle with the availability of pre-built complete upper receiver assemblies. The folks at pmarmory.com know their stuff.  I am well-pleased with my purchase and the entire experience was hassle-free.

Thanks again!
