My friend has a build with a Noveske 12.5 barrel. This is the AB numbers I ran off his velocity of 2369 fps with eld-m’s.
Geissele GFR Maritime Reconnaissance 6mm arc write up and review
- Thread starter JohnDeereGuy1996
- Start date
For comparison to a 12.5in 6arc, here is my SR-15 14.5in with Black Hills 77gr OTM at 2607fps.
Great info! I should have said out to 500y (about as far as I want to shoot a 556). Certainly better long range performance with the ARC, but I don't love the 1 MIL of drop from 800 to 850.
I will say that the idea behind my 14.7" is to compromise somewhere between the 11.5" and 18" which I think it will do well (and the 14.7" is probably what I'll end up keeping if I can get the lighter bullets to a speed to help me hold coyote fur to 300y)

The plan is to put a ZCO 420 on the 20 inch stratomatch and ZCO 210 on 14.5, but that’ll take a bit to save up cause I decided to venture into the custom 2011 game 
. In the meantime I’ll vulture optics off my ar10s.

finally got the gfr scoped properly to a more fitting optic and got it zeroed. Rifle hadn’t been shot since doing this review. Added the hux 6k as well and shot two 5 shot groups back to back. These weren’t cherry picked and were the only two I shot. Used 108 grn eld match. Maybe it’s just me but for a chrome lined barrel that’s pretty damn good to me.
Impressive rifle. I will eventually try one of these out in 16 inch form if they continue to have good feedback. The main thing I am concerned about is the bolt life over the long run. @JohnDeereGuy1996 thanks for the info. How many rounds do you have on it now?
I’m only a little over 100 or so. Haven’t got to shoot much lately unfortunately.
Also these new rifles come with no magazine and the geissele mags are unobtanium now. So I have a 3k rifle with no magazine. Real nice geissele.
These work in the Geissele rifle just fine if you are okay with the looks.
If a maritime reconnaissance is successful no shots are fired, so no magazine = no big deal.

These (and 15rds) were briefly in stock yesterday at almost reasonable prices.

The barrel extension is longer, so proprietary upper and barrel. Unsure on the bolt. Geissele has mentioned the barrel extension previously as to the reason they won’t sell individual barrels in 6arc.
Pick my 18” up on Tuesday. Will give a report once I have it in hand, also went ahead and got the 6k can for it too. Will be mounting a ZCO 4-20 on it. Sure hope it comes with a damn mag!!!
I am not sure it makes much difference but rather than a 6mm, I just bought the 30 cal version.
Not one bit. I already had 6 .30cal cans, so I figured why not get a 6mm can to dedicate to it? I'm very happy with the can, but I wouldn't be opposed to the CAT Noah either.
