Not necessarily a fair comparison.
You're not playing the lottery with an M305. Inspect the bolt and receiver to make sure it's not MIM. Then fully expect it to have all the small foibles they have. You can fix and tweak all the issues with them for next to nothing. Indexing the barrel is the only tricky part and if you make a simple jig for the barrel, a solid vice and 1-5/8" wrench.....done.
The only part that's going to cost you money is a replacement M1A/USGI rear sight assy (90 to 100 bucks shipped max) Well it will also cost you a bit of time to do some simple research and do the work. You end up with a great rifle. There's guys dumping rifle that have already been tuned all over the EE for around $600 even.
The NEA102.....that's a lottery. And it costs a lot more to just play that lottery off the hop....and you can't fix the problems in your basement if you lose that lottery. So it's warranty, getting ####ed around by ####ty Canadian customer service etc....
You MAY get a good BCL102, you may not. For those that lose that dice toss, it never seems to go well.
I would go STAG 10 if I really wanted an NR AR10 but honestly I've heard mixed nonsense on these too.
Personally I won't be giving a dollar to any Canadian companies for any Canadian made firearms any time soon. Nothing but beta testing, half baked products, shady customer service and confusing warranty work. #### all of them. Sorry. The M305 isn't a dice toss. You already know you're going to get a rifle with minor flaws. But you can fix the flaws easily at home and get that thing firing lead quick time every time. It's an outdated platform. Not very modular (if that's your thing, it never was mine). It's "old" and it's not an AR type design so it's not popular anymore.
