This is an example of a great way to get away with a NYS legal ar15 that doesn’t look like a neutered gun. Honestly I am building a similar gun to add to my collection, and this weapon, build with Rock River Arms upper and lower, 2 stage trigger, Magpul PRS stock, stainless barrel, and free float handguards for around 1,000 bucks. Thats no BS. I’ve seen the stuff at BGC, and they are usually overpriced compared to what is normal for a M4 look alike. CMMG, a company that does ar’s will sell you a built from parts ar-15, m4 style that is test fired for $550.
