Re: AR-15 choice
We have tested nearly every manufacture of AR-15, or M-16 from A-1 to A-7 yes there are even more variants then that, from the USA, Korea, China, Israel, Brazil, Taiwan, Canada, and Belgium. Of all the manufactures of kits, parts and finished firearms Olympic Arms does about the best job.
After testing dozens of firearms from all the above, they tested higher then any of the others for reliability and accuracy and on our recomendation were selected by the British for use by their SAS, and Gurkha units, and the Malaysian government for their special forces units. They also have the best guaranty in the business.
It is one of the simplest firearms to build and you can do it with only a few tools, may I suggest a Williams set trigger and a free floating hand guard as well as the flat top upper receiver. My wife has the collapsible 3 position stock and a 16 inch heavy national match barrel with the afore mentioned parts and shoots ground squirrels out past 300yds with few misses.
