I have a 7.5" NEA in 7.62. I got recently just got it, so I haven't put too many rounds through it. So far it's been great. Love it. Glad I got it.
It did feel like a gamble buying it. I did a lot of online searching to see if it would be reliable etc., but there is basically nothing. I saw one video from a reputable guy (name's Ryan - from funker tactical videos) on You tube and that made me feel better. But besides that: nothing. He had the 14.5" and explained how they modified the bolt and feedramps for the larger round
Anyone out there with one, please review it and share.
I have a success story thread here on cgn.
More pioneering.
Even NEA should have videos showing the quality of their product. Results of testing.
I'm happy with mine since it's been running great so far. A 7.5" barrelled AR in 7.62x39 seemed like the best idea anyone ever, in the history of mankind, has ever come up with. - that's why I took the gamble.
