Let's be honest, I will be surprised if the 102 even comes close accuracy wise to the kel tech RFB I had that would shoot 1moa with factory premium ammo. Going off how other nea products have performed in my hands, 3moa is my guess
Yeah, I would think there is some advantage? Less barrel whip maybe? But I'm with you there on the RFB, I considered selling mine and grabbing one of these, but it would have to be substantially better to make up for the longer OAL. Every time I think about selling the RFB I fall in love with it again. It's just so small and handy in 308.
Oh and I meant real bench rest, the sled mounted rigs with the massive bull barrels

I know all about that Lol, the proof barrel was the best upgrade I've ever done to a rifle, went from a front heavy pig to a... well balanced pig.
The reason behind large barrels is barrel harmonics, or the lack thereof.
Slim barrels flex and vibrate a lot when a round detonates and a bullet passes through them, the larger the barrel, the less flex it will have up until a point where there is no flex at all, that's why you see people basically shooting unprofiled barrel blanks (and even larger than blanks) on railguns at some bench rifle competitions. A shorter barrel will be more accurate than a longer barrel of the same profile, too.

Very cool, thanks
I was responding to Dilli specifically on that one because I know from reading many of his other posts that he trains with his NR rifles like most people train for 3-gun with an AR.
If it was just for hunting or casual recreational shooting I would agree with you.
Exactly, they also expand and contract with heat slower and more consistently but in a field rifle you trade off looking for the perfect balance between stiffness and weight. It's very hard to do with a barrel 18.6 inches or longer.
This is why I handload a lot of my ammunition, I can tune the round to match the barrel harmonic so the projectile always leaves the muzzle when it's in the same place as the round before it which increases accuracy.

Yeah I know but I didnt expect it to be that bad...lol
I have my ACR barrel at the machine shop right now to have it reprofiled to a pencil barrel and have my brake reworked as well
I got to see a cool APC adapter in the works
Cool that's my rifle he has there, I'm passing by tomorrow morning to check it out
Kinda a random question here but I had seen pictures either on NEA's facebook page or somewhere on the web where there were NEA102/25's without ejection port dust covers. I'm assuming they'll be on the rifle but if not,or if a guy wants a custom one does anybody know where to get some sweet laser engraved ones in AR10 size?
The pics I saw on NEA's FB show the receiver without them installed, but you can clearly see where the pin would go... I would be disappointed if they did not come with a dust cover yet the place for them to be was there...

I would be disappointed if they didn't come with a dust cover, more so if there was no provision to attach one. I really see no reason not to include one.
