I have a neighbor that wants to get his first AR15 in 556. He is willing to spend $2000+ on the AR. I am knowable on AR's, but I have older knowledge, not the information for newer AR's that are available on the market today. He is looking for a tier1 AR with a 16 inch barrel, with a threaded flash hider. I told him reliability and accuracy should be the main requirements with his purchase.
I told him to to get a 1/8 WYLDE barrel, also a 2 stage trigger, with a M16 bolt carrier, with a CHF, or nitrated barrel. I am not sure if he would wants a DI, or pistol gas system. What is available in the market today? He wants to eventually put an ACOG on this AR.
Please give me some recommendations on what features he should consider. Obviously the AR15 should be available to be bought online. I don't want to steer him wrong. Buy once, and buy right.
Thanks in advance(y)
