Nemo Arms M210

[Whitetail3]

Hey all, first time poster but long time reader. I have the chance at picking up a Nemo M210 which is a gun I have drooled over for years now, on a good deal. I’m looking for some real world feedback as to whether or not it’s worth the coin. I do know about the past quality issues but recently I haven’t seen any negatives about them. Any help and real world experience would be greatly appreciated!

Side note; I’ve also been looking hard at Noreen firearms newest 300 win mag AR platform. It’a priced a little better. But I also do not have any first hand experience with it, nor can I find too much modern information on it.

I put three rounds through one a couple of years back seated at a bench with the rifle on a bipod with no rear bag. It was cool, but there is a caveat.

It was set with the gas system for suppressed use, but without the suppressor, so it was manually cycled and certainly did not impart the same recoil on the shooter as it would have when gassed for full operation.

That out of the way, their buffer system is really cool and if I wanted a magnum semi auto I'd seriously look at one.

I know of someone that has some thoughts on the magnum ar rifles. Paging @lowlight...

Care to elaborate on your concern? Don’t own, and probably never will, a Nemo rifle in 300WM, but a really quick Google search didn’t bring back stories of blown up rifles. I certainly didn’t spend much time looking, but would appreciate any links or insight regarding failures.

My experience was a 30sec and 3rds fired exposure, and anything pointing towards a flawed system identified by those with more time and rounds under their belts would be good for me to know so I don’t inadvertently pass along undue praise.

It's a magnum gas gun, look up Noreen, DRD, just recently at SHOT one blew up...

There is no reason to have a magnum gas gun, and unless the system has a firing pin safety and spring system to prevent it from moving forward, you have a risk. The heavy carriers let the pin go forward and denotate out of battery, was standing 2ft from a 338 when it happened, and dodged the shot show blow up by refusing to shoot it. 30 rounds later it cratered sending the friend of mine to the hospital.

The Nemo could be the greatest example of a magnum gas gun on the planet, I still would not own or shoot one for any money. Have I shot one, absolutely I have, would I today, fuck no.

99% of the shooters out there cannot accurately drive an AR10, what makes you think you can do any better in a magnum when 1/2 the bolt gun people with them do nothing but flinch. Magnums are a tool in the toolbox to either extend your range or hit something harder. What do you have to hit harder that often where you need a magnum gas gun? and if you are shooting ELR the focus should be on slow accurate fire, not fast. It's a solution in search of a problem, that creates more problems than they attempt to solve.

it's your face, you shoot it, don't like my opinion, go out and form your own.

I’ve never heard of a 300 blowing up, just the Lapua’s. But I could be wrong. Which is why I posted this thread looking for insight from those with knowledge!

WHAT! They had to pay his med bills right??!!

Thank you for the reply. As I said, I'll likely never own one, primarily for the (im)practicality you mention.

Wonder if NEMO has enough units in the field to know if their design has it right or is simply a timebomb.

Variable ammunition heating from the fired gun has to be accounted for in the move from a bolt gun to a semi and especially as the cartridges grow in size. With a bolt or manual bolt drop the user can chamber the round and maintain a known dwell time. To compensate with a semi, that immediately loads the round, a lot has to done with thermal management.

I help teach a one day local class and talk about how different positions affect MV and starting from prone fire 5 rounds from different positions with the Magnetospeed attached to show MV real time. I finish back at prone with a hot chamber and show the MV difference between a cold and hot chamber.

Hi,

What is the maximum MV increase/decrease you guys have seen in regards to ammunition temperatures?

I am not a gas gun guy so curious as to what kind of numbers you all are seeing. In my bolt gun test I have never gotten over 100fps difference, even when trying to; but without going overboard in trying...

From reviewing some of the big magnum gas gun failures.....the increased pressure from the "heated" ammunition is not their failure point since most of the "bangs" happen before the carrier group is locked into place because the mass of the carrier group and firing pin floating is the problem.

Detonation is happening as the round is being pushed into chamber and the firing pin "taps" the right spot.....

There has to be a reason that Lloyd over at the former RND Edge rifles designed and built his big and big big magnums with a hybrid style firing pin system as to where it did not really "float" but was not "fixed" either. That guy was probably the first person to build a 338LM in a gas gun and definitely was the first to do so in Cheytac calibers. None of which have ever had out of battery detonation (That I have ever heard of or researched)....even when they were being tested by the Army on UAV Helo...

Sincerely,
Theis

The most I observed was a 25fps MV increase but that was only from a cold chamber (70deg ambient) firing 20 rounds of factory 6.5CM in a Shilen light target contour.

One puny data point

 

[Lowlight]

The two I was present for were out of battery detonations, the first had less than 10 rounds through it.

I know the Alexander Arms have a spring in there to try and keep the pin away from the bolt face on chambering. Sword also has a block in place to prevent firing pin issues. The others not so much, unless they have updated their designs.

Again, aside from the military using these in a place where running a bolt is not practical, as in the drone platform. What problem are we trying to solve with a magnum gas gun? The military I can see, punching thought something with rapid follow up shots, but on the civilian side, it's a connoisseur system, meaning you better be on your A-game to shoot accurately.

Magnum detonations in a semi-auto platform are not pretty, even when it funnels out the mag well, there is still a lot of damage which causes shrapnel to the shooter.

I was checking their 300WM offerings out not too long ago, Noreen as well. Everything LL has said pretty much rings true of the Nemo and Noreen offerings. FWIW, people say great things about the Falkor Petra 300WM in comparison but not much is said about them at all.

IMO, reliability should be the main focus on any semi magnum platform. You don't really need a laser, you just need it to punch hard as shit every single time. So no, the Nemo Arms 300WM is not especially worth the coin in my mind— I'm just not inclined to flirt with it given that the model roll out was fuckered. I could put half that money into a mag fed bolt gun and have the best of everything except rate of fire, it just doesn't equate to me personally. It'd still be cool as hell, you can never have enough gun, but recently and for a decent price I passed on the Nemo just because the platform originally had (and still may have) problems.

Hi, has NEMO addressed any of those problems mentioned?

I hope so because I just got a brand new one. 2023 Nemo Recon. I may just call them tomoorrow and ask, I called once last week and someone picked up immedatly and answered all my ammo questions.
